VAZ 2107 Injector stalls ride. The car starts and immediately stalls: causes and ways to solve the problem

04.11.2020

Despite the development of the autoinadustria, the classic VAZ models still enjoy in great demand in the CIS countries. The latest models of "classics", namely VAZ-2107, equipped with an injection inlet system. She is more reliable than carburetor. But what to do if the VAZ-2107 starts and stalls? Injector - the system is more complicated. But the problem can be solved with your own hands. Let's look at how to do it.

Will the starter turn?

At first it is necessary to check the voltage in the onboard network of the car. To normal start the machine, this indicator should not be below 12.5. To accurately measure the voltage, you must use a voltmeter.

Starter is a mechanism that requires a large starting current. It is this node that turns the crankshaft for launch. Therefore, if the VAZ-2107 (injector) does not start, the reasons may be banal - low battery voltage. Remedy - charging battery. You should adhere to the indicators at 12.5-14 volts.

Breakdown starter

If you have a closure in the case or wiring, the anchors should replace the damaged part. How to check the element? To do this, use the multimeter. One wire is connected to the friction site of the brushes, and the second one on the anchor axis. If the appliance arrow has deviated from the values, it may be an anchor or winding fault. Check brushes. They should easily move, and their springs are elastic and put anchor well. After replacing damaged items, run the motor again.

Ignition system

What if with a well-charged battery and a good starter does not start the VAZ-2107 (injector)? Causes can hide in the ignition system. Here it is a contactless type. The first thing to check is the condition of the candles. They can simply "fill". Remove the items out and inspect the state of the electrode. In the presence of plaque, it is necessary to clean the part in the alkaline solution and tighten it back. You should also check the gap between the electrode. To do this, use a special probe. The normal indicator should be ranging from 0.7 to 1 millimeter.

How to be if the indicator does not match the norm? The electrode can be bend. But do it carefully. If the indicator is less than the norm, use a minus screwdriver. If more, knock the electrode in the metal part (for example, the valve engine lid). It will be worthwhile to check the candles for the scope of development. This uses a special pistol. Spark itself must be blue. If more than 60 thousand kilometers passed the details, they should be replaced. Also, when this period is reached, the ignition distributor changes are changed.

When candles are filled

If the VAZ-2107 injector is poorly started (grabs, but does not start), it means that the combustion chamber is overwhelmed with gasoline. The normal fuel ratio to the air should be 1:14. Such a problem often happens on such cars. When starting, the fuel pump shakes a lot of gasoline. By the way, on the injection motors it is electric, submersible type. Installed directly to the tank.

How to dry the candles without removing them? To do this, when starting, you should open the throttle. It is mechanical here and is activated by pressing the accelerator gay through the drive of the cable. So in the combustion chamber will go more air and the engine will immediately start.

TRABLLER

In the VAZ-2107 car uses rubbed ignition. If you should check the status of contacts on high-voltage wires. When changing the season, condensate is formed on them. The rubber has five outputs.

Four of them go to cylinder candles, and one (central) - on the ignition coil. On metal ends is often a white flare. Because of it, the slider will not be able to transfer pulses to the coil. By the way, it will be worthwhile to check the ignition distributor itself. Looks like a detail as follows.

If it is burnt, the item should be replaced. The price of the new element is 150 rubles. If, when you start the motor on the ignition coil, a spark is formed, a high-voltage wire should be replaced. He also "breaks" on the candlelight. You can see it in the dark. Little sparkles of blue are visible near them. In this case, the wires are changed by a set. They are inexpensive. There are new elements of about 700 rubles.

Problem with electric pump

Previously, one of the main problems on the domestic "classics" concerned the fuel pump, which was constantly overheated. But in the injector "seven" it is electric and cooled by the gasoline itself, which is in the tank. If electricity is not served on the item, the machine simply does not start. The first thing to pay attention to is the fuse block.

On the lid is written, which one of them is responsible for the fuel pump. If the fuse burned down, replace it. You can use a 15- or 20-ampered element.

Determine the serviceability of visual

Is it possible to check whether the voltage is supplied to the fuel pump, without a multimeter? To do this, when the ignition is turned on, it is necessary to listen to its work well. When turning the key in the third position, it should publish a characteristic hum. It can be heard in the back of the cabin. If it is not and the VAZ-2107 (injector) does not start, the problem is in supply voltage. It is worth checking the pump relay. It should make characteristic clicks. Experienced motorists carry spare relays and fuses in case of sudden breakdowns. This relay is located on the shelf under the glove compartment.

Low pressure

Why not start VAZ-2107 (injector)? Problems can be hidden in a low pressure level of the fuel line. For a normal launch of an injection engine, at least 2.8 atmospheres are required. You can check this by disconnecting the feed tube from the ramp. Use the pressure gauge for this. Malfunctions with pump can manifest itself due to frequent overheating. But how does this happen if it is immersion type? The fuel pump kills riding on an empty tank. If the light is caught fire, should not be tightened with refueling. The cost of the pump for injector "seven" is 3 times higher than for carburetor.

Filter condition

The following situation happens. You arrived at the destination, turned off the engine for two minutes, got into the car and could not run it again. What to do if the VAZ-2107 (injector) should be a scored fuel filter. Its replacement period is about 50 thousand kilometers. Also, the wines of the launch is a dirty air filter.

If he passed more than ten thousand kilometers, then it is subject to replacement. Otherwise, you will come across the problems of launch.

VAZ-2107: the injector will start and immediately stall

In this case, the mass flow sensor should be checked. It is located immediately behind the plastic filter housing.

This element perceives information about the air flow and transmits it to the control unit. As a result, the electronics decides on the composition of the combustible mixture. The block can intentionally adjust the fuel and air concentration. The DMRV sensor resource is 150 thousand kilometers. When dirting the element can send false readings. Because of the VAZ-2107, the injector will not start either working and immediately stalls. You should also check the condition of air nozzles for tightness. If necessary, replace.

DPKV

If, with a good fuel system, the VAZ-2107 car (injector) does not start, if it is faulty, the control unit will stop the fuel supply due to the lack of information about its position. The cost of this element is from one to one and a half thousand rubles.

Conclusion

So, we found out for what reasons the VAZ-2107 car does not start. As you can see, detect and eliminate the malfunction with your own hands, and for a small price.

Situations when the VAZ injector is immediately started, after which it stalls immediately, it happened quite often. And all because of the fuel injection system (forced type). To correct this situation, auto owners often use a heating candle, but this is not a solution to the problem, but only a temporary measure. If the VAZ 2107 starts up and stalls immediately after turning the key in the ignition lock, then in most cases it indicates a problem in the delivery of fuel (scored or runs incorrectly fuel pumps), or the quality of the fuel used leaves much to be desired, and the nozzles are simply scored. And the car starts solely on the residues of fuel in the cylinders.

Search for defective component

So, what do you need to do if the engine is easily started, but after that it immediately drops turns and stalls? First of all, you need to check the availability of a car on candles. If some of them are covered with a layer of Nagara, the engine a priori cannot work normally. It first starts due to the movement of the starter, but immediately it slows down, since several cylinders physically cannot withstand the entire load from the crankshaft. The carburetor, by the way, may also fail because of such a problem.

So what is the cause of the engine malfunction? If the machine starts, then, at least, everything is fine with spark. That is, the electrician works as it should be. It will not be superfluous to unwind the heads and try to find those candles that are covered with a layer of Nagara. It is possible to cleaned them with the help of burning over the gas burner and cleaning alcohol (it can only be done when the contacts are cold).

The injector itself can also clog. In this case, simply does not work fuel supply to the combustion chamber. These actions should be made:

remove blocks and check the dampers;
check the operation of the sensors;
check whether the engine is working normally at a temperature of over 80ºС.

Naturally, the fuel pump itself can be harmful. In the injector at the time of launching the motor, it is rotten by automaton at the expense of the starter, and then it goes from the generator. If one of these components work incorrectly, the machine is simply stupid. Here again we are talking about the residual amount of fuel in the cylinders. If the motor immediately stalls, and the starter is unevenly working with it, then, most likely, the problem or in it, or in the ignition lock.

You should try to replace it with an obviously good and re-test the operation of the engine. In the extreme case, contacts are simply clamped.

What if the problem is in the ECU?

The engine may not work incorrect if the on-board computer works. In VAZ, it is he who is responsible for the timely supply of fuel, synchronization of the operation of the injector nozzle and spark plugs. When the engine immediately stalls, this indicates the mismatch of the moment of supplying fuel and the ignition of the fuel mixture.

As a rule, helps changing the firmware or restoring it to the factory state. Although sometimes it may be simply necessary to adjust the fuel supply cycle, as well as the saturation of the mixture. In extreme cases, the VAZ 2110 (or later model) will have to replace the entire unit of the ECU or turn it off, translating the engine into operation mode only from mechanics.

It should be noted that the engine is responsible for the operation of the engine, but also a bunch of sensors, which is regulated by the pressure in the nozzle, the saturation of the mixture, the moment of ignition.

That is, you need to check and their work. Although, when identifying a malfunction of one of them, a Check Engine signal should be applied to the dashboard. So, for example, happens when the VAZ 2110 starts. This does not occur only if the ECU simply does not receive signals from the sensors. It is worth noting that in the model 2107 by default the computer does not put, but the injector does not work without it.

Similar problems arise and then when the carburetor is synthetically reworked under the injector, but it is left to the former on-board computer. It simply change the firmware, plug new modules, but you need to understand that it is originally not designed for such a job. Thus, if the carburetor is reworked, then with it you need to change both the ECU on the compatible model. Fortunately, VAZ took care of their release.

So, if the injector is starting and immediately stalls, then the main reasons for such a malfunction are disorders in the operation of electronics (including the ECU), the incorrect operation of the fuel system or the gasoline filtering problem. To identify the main reason is not problems. In extreme cases, you can always contact the center of a hundred. But it is worth remembering that any adjustments to the operation of the on-board computer can be entered only with a fully suitable engine.

If your car VAZ-2107 car has a malfunction, as a result of which the engine stalls, then further movement becomes problematic. But finding the cause of this malfunction for the injection engine "seven", quite difficult without the presence of diagnostic equipment, since the reasons for which the crankshaft is rotated is unfortunately a lot.

Most often, the injection motor, stalls in the idle mode. A throttle assembly with an idling regulator (RCX) can be involved in this malfunction, since in the process of engine operation, the throttle assembly can be strongly polluted, which leads to the encoding of the RCH rod. To check this assumption it will have to be removed, and in the presence of pollution, it is gently rinsed with a well-washing butter mixed with mud.

If you have a VAZ-2107 alarm on your car, which works with an electrical chain of a fuel pump, the reason why the engine stalls can become a poor-quality work of those who installed it. If they did it on twists, then a badly compressed twist will weaken over time and the contact is lost. As a result, electric fuel pump ceases operation.

A possible cause, due to which the engine stalls, it may be to overcome the combustible mixture. You can check this by turning the spark plugs. If they are covered with black naigar, then the mixture is rich. The amount of gasoline supplied to the engine cylinder depends on the position of the throttle and the correctness of the indication of the temperature sensor, which is covered on the left in the back of the cylinder head. When it is replaced, it will have to partially merge antifreeze from the cooling system.

A strong enrichment of the mixture leads the failure of a mass flow sensor (DMRV). You can check its condition using a multimeter. The measurement is made between the green and the red wire (2nd and 4th terminals, if you count from the left) when the ignition is turned on. If the voltage is more than 1,002 volts, it will have to be replaced.

With a strong depletion of the combustible mixture, the engine will also stall. And its depletion occurs due to air supply behind the throttle node. Possible seats of air supply usually become the inlet system or as a result of the weakening of the details of the parts, between which they stand or because of their breakdown. The air suction site can be found with a pile that uses beekeepers. Signing the engine compartment to them, immediately will be visible, in what place the smoke is drawn. And on decent maintenance stations, instead of the pimer, use the device called a smoke generator.

You should also pay attention to the vacuum brake amplifier, since the air seats into the engine cylinders can be carried out through it. This occurs due to non-tightness of the diaphragm, which leads to a permanent connection of the intake manifold with an atmosphere. To determine this fault is simple enough, for this you need to take a slog connecting the vacuum amplifier with an intake manifold. If the engine does not slander, then you will have to change the vacuum brake amplifier.

5 reasons why stall VAZ-2107

Hello everyone today want to talk about the reasons, because of which your car VAZ 2107 stalls, and in connection with this unpleasant annoyance you can no longer continue to move on your iron horse. Today we will try to consider the main reasons why your engine stalls. Of course, a lot of such reasons are quite a lot of such reasons. The first reason is the problem with the idling regulator (RXX) usually the machine stalls at idle. RHX may fail due to contamination, and this leads to the fact that the rod clinite. To make sure you need to remove the RCH from the seven and in the case of pollution is rinsed well. It is advisable to use a liquid that blends oil well.

The second reason, due to which the VAZ 2107 stalls is alarm system (unless of course it is installed) In most cases, the alarm system works with electric chain of the fuel pump, and where do you ask? And despite the fact that the unscrupulous mechanic who connected you the alarm could make his job from here and could follow problems. Especially if they did everything on twists, then over time she weakens, and write everything as they say. Power supply to the pump ceases to act, as a result of which VAZ 2107 will not start.

The third reason is a too rich combustible mixture. You can check this version by unscrewing the candles if the contacts of the candles are covered with black nagar it means that the mixture is too rich. For how much gasoline is supplied to the cylinders, corresponds to the position of the throttle valve, as well as the readings of the temperature sensor, by car VAZ 2107 this sensor is located on the left in the rear of the block head. If there is a need to replace the temperature sensor, then you have to merge what, then part of the antifreeze. The failure of the mass flow sensor (DMRV) on the VAZ 2107 also leads to the enrichment of the mixture. You can check the DMRV operation using a multimeter. If the voltage is more than 1,002 volts, it will have to be replaced.

The fourth reason is a strong depletion of a combustible mixture. As a result, your "seven" will also slander. This is mainly due to air supply. The main seats of the supply are inlet system, or weakening fastening in places where they cost. To search for air suction, a smoke generator is usually used to see the place where the smoke is drawn.

And the fifth reason is a vacuum brake amplifier. Since the air seats can pass through it. This happens due to a leakage diaphragm. You can change the faulty vacuum on the VAZ 2107 by moving the hose that connects the vacuum amplifier and the intake manifold if the engine does not heat up then, most likely it will have to change the vacuum.

Well, that's all we looked at the main reasons why the VAZ-2107 car stalls, if you had other reasons, then write in the comments. So far.

VAZ 2107 does not hold idle carburetor

VAZ 2107 is not the best model among the cars of its class, if compared with foreign approximate analogs. However, thanks to the low price and the available service, the car has been popular in the entire post-Soviet territory. The car was produced since 1982 until 2014. That is, the oldest model has age for more than 30 years. For such a period of operation, the owner will be able to face all types of faults and explore most of the causes of malfunctions.

After several years of operation of the VAZ 2107, as well as almost identical model 2105 begins to show a new character with changes not for the better. The malfunctions associated with the power unit and its body kit are different, but symptomatic:

the engine periodically stalls;
does not hold stable momentum;
unstable work at idle;
it's hard to start;
insufficient power;
increased fuel consumption.

All faults appear for two reasons: violation of adjustments or wear of parts.

Unstable operation of the injection engine

Typically expressed in spontaneous change in engine speed. It is observed while driving and at idle. The most common cause of turning rumble in injection units VAZ2107 / 2105 is the failure of the DMRV (air flow sensor).

This device controls the amount of air entering the engine. Based on these data, the ECU regulates the supply of a combustible mixture with the optimal ratio of fuel and air with different engine operation modes. Accordingly, in the absence of this balance, the engine turnover is beginning to depend on the amount of incoming oxygen. That is, breeze breeze - revolutions increased, verse - decreased.

Make sure that the DMRV is defective quite simple. Disconnect the device connector, and the computer will switch to emergency operation. In this mode, the fuel supply is regulated by the throttle position. If the car began to behave adequately, the DMWR is faulty. You can drive it, but a little power will fall and the fuel consumption will increase.

The failed air flow sensor was not subject to repair, with the exception of its pollution, so you can try to clean it.

Algorithm for cleaning DMVR VAZ2107 / 2105:

Remove the sensor along with the protective casing.

Unscrew two screws and pull out the sensor from the base, without touching the surfaces of the active element (current curved wire).
Casing rinse any dishwashing agent.
Using a cylinder with a cleaner for DMVR or for a carburetor, based on alcohols (without acetone), clean the surfaces gently.
Pour 3-4 times abundantly, the liquid must flock.
Dry the device.
Collect the block in the reverse order.

If the problem is not eliminated, you will have to buy a new device.

Unstable carburetor engine

The nature of unstable revolutions of the VAZ2107 / 2105 engine with carburetors is the same as in an injector, in uncontrolled air supply or fuel into the combustion chamber.

But in this case, the carburetor is responsible for the preparation of a combustible mixture. This is a fully mechanical device that is responsible for the optimal ratio of oxygen fuel for different modes of operation of the power unit.

Despite the fact that the fuel and air inputs are filters, they can work inefficiently, as a rule, due to a long service life exceeding the indicated in the standards. As a result, the jets of the carburetor are clogged with small particles.

Drivers with great experience are not very ceremonially, thrown the carburetor VAZ2107 / 2105 in a bucket with gasoline for a day, then blurred from all sides with compressed air and the carburetor seems to be working fine. This is a normal solution, but flammable. Among the causes of the engine work disorders, which are due to the carburetor breakdown, can be allocated:

displacement of the position of adjusting screws from impact or vibration;
an increase in the diameter of the loop of loans due to wear;
wear an axis of the flap restricting its move;
clogging of jets;
violation of tightness float.

To determine the fault of the VAZ2107 / 2105 carburetor, and it is likely to be comprehensive, start by checking the sealant of the float. To do this, remove it from the top of the carburetor (it needs to be dismantled). If in the gasoline float - throw away the float if the air is to check the water with water to bubbles. Suppose he endured the exam, then it is necessary to check the gap.

Lift the carburetor vertically. The gap between the float chamber and the carburetor wall should be 6.5 mm.

Install the carburetor cover and boot the engine for 30 seconds. Remove the lid. The gasoline level should be exactly the coincidence of the middle of the conical surface of the carburetor housing. If it didn't work out, it should be a little bend an angle of the ice rod.

Over time, air and fuel jets are either clogged or wear out. In the first case, they must be cleared and blow. In the second case, check the bandwidth of the jets with a tank with water installed above the fastened gibera per meter. They are connected by the tube. Below is the measuring flask. Measurements occur in units of SM3 / min. Depending on the labeling of the gibber, the volume of fluid collected in a minute in a measuring flask must be appropriate.

It's much easier after 7-10 years of carburetor's work to buy a set of juses and replace them.

Those who use gas installations should know that the carburetor is not used in goal. Over time, inside dry juices, an oxide is formed, which clogs the fuel holes. Machine on gasoline may not start. It is recommended to periodically use gasoline.

Carburetor adjustment

The carburetor adjustment lies in several actions:

Adjust the position of the float above the method described.
Check and install the "quality" and "quantity" screws in the initial state. Wrap them until you stop and unscrew by 2-3 turns for the "quality" screw and 3-4 for the "quantity" screw.
Connect the tachometer or autotester to the terminal "to" ignition coil, and the second probe to the case.
Create and warm up the engine to a temperature of 90 ° C

Winker "Quality" Set the maximum speed at idle. The supply of gasoline increases when the screw is rotated counterclockwise.
The screw "quantity", set the revolutions more, approximately 80-90 rpm.
We determine the quality screw, whether these revs are maximum, if not, then we repeat the procedure.
If the position of the number of the number of the number does not affect the engine turnover, wrap the quality screw so that the turnover fell to 800-900 rpm.

Such adjustment of the carburetor may not be quite accurate, but does not require special equipment.

If the car is stalled

The engine that suddenly stalls does not only create inconvenience when driving, but also is a security threat to the driver and passengers. There are several reasons.

Blinds at idle:

failure of the idling sensor;
the failure of the throttle sensor;
the outflow of the throttle position sensor.

It stalls on the go:

termination of fuel or air due to a contaminated filter;
fault of the fuel pump;
clogging of carburetor jets;
engine overheating.

The diagnosis of the car, the engine of which stalls in the most unexpected places, it is better to start from checking the idle sensor.

Check its performance simply. Remove the device without removing contacts, or connect them after dismantling. Keep the device in your hands, put your finger on the conical needle and ask the friend to turn on the ignition. If you feel jolts, then install the device back. Idling sensor is working.

If the throttle sensor has failed, the car will not only stall, but it does not start, because the computer will give the team to the maximum fuel release, the candles will sing the motor stalls.

If you are on the road by car VAZ and there was a problem with the throttle sensor, it is easier not to bother and contact the nearest service, but if you reach the garage, you can use the following instructions:

Remove the sensor.
Two mm drill drilled in a circle plastic lid.
Remove the plastic platform of the top contact group.
On the bottom platform, you can read WD-40 or alcohol tracks.
The same thing with the contact group of the upper cover, but do not fade them, they are then prematurely eaten paths.
Collect in reverse order.
By contour, wake any glue for plastic.

Not enough air

Often the car starts well, it goes on the scene, but only it is necessary to disable the sublicas, the engine stalls. It speaks only about one thing - a shortage of air. Most likely, air jets are clogged. They need to unscrew and clean. Then check, the machine should not blame without a suction.

There is an incredible number of reasons for the poor quality of the car's aggregates with similar symptoms, but only a specialist with a set of professional tools for diagnosis can understand them. But if you feel confident - dare, in car services VAZ are waiting for you.

Why jumps idle on VAZ 2107

What to do if it jumps idle on the VAZ 2107, is there any panacea from this? A lot of trouble gives the owners of the fuel system, but you need to consider one feature - it is not always to blame. For example, in carburetry motors with a classic ignition system, the likelihood of damage to the contact group in the case of instability of idle speed is large. But with injection motors, everything is somewhat easier. And now about everything in more detail.

Why engine speed unstable?

If we are talking about a carburetor, then several reasons can be distinguished:

The carburetor is clogged, the movement of air and gasoline becomes impossible.
The operation of the electromagnetic valve is broken - the winding or clogging of the gibler burned down.
Fuel filters or air are clogged.
Wrong adjustment of the carburetor VAZ 2107.

In most cases, the culprit becomes an electromagnetic valve. Its appearance is shown in the photo. It is necessary in the power system for the next goal - opens the fuel supply when the ignition is turned on and closes when it is turned off. Consequently, the motor immediately after turning off the ignition stops.

Electromagnetic VAZ 2107 carburetor valve is a small device consisting of the following elements:

Case.
Winding (one end is connected to a metal housing).
The rod performing the valve functions, which opens and closes the fuel supply at idle.
Copper jicker with holes. Please note that the jacks are labeled, there are several sizes.

The solenoid valve operates only when the ignition is turned on. If suddenly there was a break in the power circuit, you can temporarily connect the center wire of the instrument with the plus output of the battery. Just try to repair repairs as soon as possible.

Preparing for idle adjustment

If the cleaning and disassembly of the carburetor VAZ 2107 is not planned, then one screwdriver will come in handy from the tools. The device for measuring the speed of revolutions (tachometer) is installed in the dashboard. But it is worth getting a mixture quality indicator. With it, you can make an air-fuel mixture in an ideal proportion. This article will be described about the adjustment using this instrument.

Before working, you need to warm up the engine to the operating temperature. Recall that this is the temperature of about 90 degrees. You also need to put the air purification filter to the place to simulate the normal operation of the motor. Make sure the float setting is performed correctly. The fuel level in the chamber should always be stable.

Many requirements are available to ignition, gas distribution. Be sure all the gaps must be correct, and the ignition advance angle is configured for the gasoline used. And most importantly - fully open the air damper at the time of adjustment. That's all, briefly contain preparation work, you can now begin the idle setting procedure.

Setting idling VAZ 2107

Carefully inspect the carburetor, there are several screws - the quality of the fuel-air mixture and quantity. It is with their help now and try to adjust the carburetor. Of course, such a device as a gas analyzer is not every driver. However, not everyone cares about the level of CO in the exhaust. For convenience, it is desirable to have a digital or arrow tachometer. How to connect it correctly, you can find in the relevant article on our website.

So, run the motor and rotate the quality screw. Listen to the engine, you need to stop at the moment when the number of crankshaft turns will be maximal. After that, it starts to rotate the screw of the quantity and seek the frequency of 1100. And the last step is the quality screw of the quality, you install the frequency of 800-900. Please note that if necessary, the idling adjustment must be repeated.

Instead of a candle, screw the mix quality indicator and achieve the optimal color - purple blue or blue. Adjusting the quality of the mixture using this instrument is simplified. True, it will be necessary to twist the quality and quantity screw several times.

And what about the injector?

Everything is easier here, since the adjustments do not need. Cause - Everything is responsible for a smart onboard management system. And specifically for idle - regulator (RCH). Someone can call him idling sensor, but this concept is rooted incorrectly. The fact is that there are two types of devices on injection vehicles - sensors (read) and actuators. The idling regulator is a stepper motor, it does not measure anything, but on the contrary, opens and closes the air supply over the special channel.

It is possible to determine the breakdown of RXX only on external signs and that relatively. The fact is that the test lamp will not light up on the dashboard, if it suddenly orders the regulator to live long. But if unstable momentum is felt, or they are missing at all, and the engine twitches and stalls, then first of all, of course, it is worth checking the efficiency of the RXX. It is worth noting that sometimes the "check" can light up with defective RXX. This happens if the engine detonates. The detonation sensor gives a malfunction signal with an electronic control unit.

Breakdowns RHX

If you have a VAZ 2107 with an injection motor, then pay due attention to the state of the car systems. If they float turns on the injection motor, then you need to watch the first thing to the idle regulator. The fact is that the breakdown of such a mechanism as RXX can lead to very sad consequences, up to a traffic accident. Here are the main signs for which you can independently determine the breakdown of the regulator:

The engine begins to "live his life" - the rotational speed of the crankshaft is constantly changing, it decreases, it increases. Consequently, the tachometer arrow constantly floats.
When you run a cold engine, the rotational speed of the crankshaft does not increase, it varies in some interval.
If you turn on powerful electrical appliances (for example, a car radio, near or far light), revolutions decrease and are not returned to the specified level.
When the neutral transmission is turned on, the engine begins to stall, if you do not pod a pedal from time to time.

These are the main signs that the regulator is faulty. In essence, any interruptions with a level of idling is the first sign of breakage or a small defect RXX. But it is time to conduct its diagnosis. Make it will be easy.

Diagnosis

The easiest method is to measure the voltage on the block to which the regulator is connected. This conclusions D and A. When the ignition is turned on, 12 V. voltage should be present in the event that the voltage is less than this value, it is worth looking at the battery and the generator. It is possible that there is an underwear of the battery. In the same case, if there is no voltage, it is necessary to check the entire device power supply chain and propagate the ECU.

Translate the multimeter to the resistance measurement mode. Between pairs of conclusions A and B, C and D, there must be resistance of about 53 ohms. Remove the RCH and connect (when the ignition is turned off) to the block. Then turn on the ignition and look at the needle behavior - it should be fully extended when the voltage is applied. In the event that this does not happen, you can judge the breakage of the RCX.

Sometimes the simple cleaning of the regulator helps. To do this, you can use sprays, which in stores sufficient. But in some cases it will only help the replacement of the device. Of course, this is not a DAAZ carburetor, the cost of RXH will be many times lower, and there will be no problems with the replacement. In the event that even after the replacement, the engine does not hold the engine, it is necessary to fully diagnose the injector.

Disappeared idle on the injection engine, reasons

List of the main, most common, reasons for the appearance of unstable nozzles or full of their disappearance on injection engines (2111) VAZ cars 21083, 21093, 21099. All faults are grouped by engine systems: ignition system, power system, control system (ECD), self engine. Most of them are easily determined by the help of diagnostic equipment, but you can find faults without it.

Before detection of a malfunction, it is necessary to produce a visual inspection of the boost space (elements of the ignition system, sensors, tubes, hoses), checking the density of the contacts of contacts in the connecting pads, tips of high-voltage wires in the ignition coil and candlelight.

Causes of unstable idling injector engines associated with the ignition system

Faulty spark plugs

Candle faults: flooded after an unsuccessful start, "breaks" isolator, the gap between the electrodes does not correspond to the norm (0.9 - 1.1 mm), the candles in a calil number do not correspond to the engine. External signs: unstable idling, uneven exhaust exhaust from the muffler (periodic or frequent pass). It is necessary to blow the candles: by pressing the gas pedal failure and scroll through the engine starter for a few seconds (so-called. Purge mode). After turning them to evaluate the condition of the contacts, the presence and color of Nagar, check the gap of the circular dipstick. Disabled candles are very often clogged with nagar or wet. But in some cases, it is visually impossible to determine their fault, so it is easiest to install a new set and check for the presence of idling engine again.

- "punched" high-voltage wires

External signs are similar to the candle. You can check the serviceability of the wires by the tester in the module mode. You can run the engine in the dark and observe the glow on the "punched" wires. In addition, it is necessary to visually make sure the integrity of the wires and their tips, the lack of pollution and cracks on them.

measuring the resistance of high-voltage wires

Faulty ignition coil (module)

Initially, we look at the coil: check the presence of cracks and damage. Then check it with a tester in an ohmmeter mode (see "Checking the ignition module"). Without past checking replacing with good.

Malfunctions associated with the engine control system (ECM)

Faulty regulator (sensor) idling (RXX)

The defective regulator rod may not overlap the air supply channel of the engine required to operate the engine on the XX under the throttle. Signs of a faulty regulator besides an unstable idling: Starting of the engine with a press on the gas pedal, jerks and a drop of revolutions when switching transmissions and moves in rolling, "floating" turns, idling, that is, no, the drop in revolutions when you turn on powerful electrons. At the same time, on other modes with a pressed gas pedal, the engine can work normally without failures, jerks and jerks. The sensor can be checked by a tester or replace verbally serviceable (adjusting the speech of its needle).

The throttle position sensor (DPDZ) is faulty

Faulty DPDS can produce incorrect information about the position of the throttle position on the control unit. As a result, at idle, the engine turnover can be greatly increased and reluctantly decrease to the norm or not to decrease at all. DPDZ can check the tester or replace serviceable.

Throttleproof closes loosely

It is necessary to check the density of the closing of the air damper removing the air filter housing. Clicking several times on the gas pedal, check the clarity of the damper drive operation and its opening-closing. If you have a nagar in a throttle unit that interferes with the damper closing density, remove it for example, the carburetor cleaner.

Faulty coolant temperature sensor (DPT)

According to the sensor readings, the control unit determines the magnitude and duration of the injection, how much to move the RCH rod and open air access to the engine. If the Dzh is defective, for example, in the cold, the block will not allow the mixture to strongly and at idle (the engine or does not start, or it will start, but will "troite"). And in the heat, on the contrary, give a rich mixture and the turnover of the XX will be overwhelmed.

Faulty Speed \u200b\u200bSensor (DS)

Signs: After stopping the car, the engine works unevenly, then the turns stabilize, the drop in revolutions when switching transmissions and moves rolling.

Faulty oxygen concentration sensor (DK)

Perhaps, a sensitive element of the sensor was faced (for example, due to the use of poor-quality fuels, the use of inappropriate sealants during the repair of the engine), heated the heating helix or the electrical circuit was defective. It may be blocked by a hole for air supply in the sensor (mud, anticorrosive). Pre-check the sensor can be tester without dismantling, but it is desirable to check on diagnostic equipment.

Causes associated with car VAZ 21083, 21093, 21099

- "SUPPLY" of extraneous air in the intake tract

Check the landing density of hoses going to the throttle node and on a vacuum brake amplifier, fastening the clamps. The vacuum hose can be over to eliminate its effect on the engine.

Not adjusted gaps in the valve mechanism

Check and adjust with the clearance washers in the valve mechanism.

Worn camshaft camshafts

You can determine visually or the micrometer check.

Violated phases of gas distribution

The timing belt rearranged on the tooth-friend. Or, when repairing a label on the pulleys is exhibited with a deviation.

Low compression in engine cylinders

Worn, broken either fixed rings on the pistons, burned the valve. To identify a malfunction can be measured by compression in the engine cylinders.

The gear wheel has shifted relative to the pulley of the generator drive.

As a result, the control pulse from the crankshaft position sensor comes not in time.

Causes associated with the system (fuel supply system) and fuel vapor searches

Torn fuel filter

The frequency of replacing the fuel filter is 30.000 km of run, but it is possible and more often with the quality of fuel.

Low pressure in the power system

Perhaps the pressure regulator on the ramp is defective (the drain channel is constantly opened), fuel pump or fuel lines are damaged. We need a visual inspection and testing of the power supply system (2.5-3.5 bar).

Spot into the nozzle

In this case, the interruptions in the operation of the engine are possible not only at idle, but also in other modes. Exhaust from the muffler with uneven frequent passes. Increased XX turns are possible due to their leaks.

Faulty adsorber

First, check the tubes going to the adsorber.

Notes and additions

When the sensors of the engine control system (ECD) lights up the "Check engine" on the instrument panel lights up.

In this article we will talk about such an unpleasant problem as the engine stop, as well as bad launch. Consider the main reasons why the engine is stallped at idle and on the go. In addition, let's talk about why the motor does not start on hot, as well as about the solution to each of the problems described above.

Common reasons for which idle is stolen:

1. The most common is - a no-power regulator (sensor), which is directly related to idle engine speed. Check in it whether the breakdown is quite simple. If the machine does not start when you twist the starter, work the gas pedal, the engine must start. If the turns start to swim immediately after you removed the leg with the pedal - 99% what is the reason in the idle regulator. The decision -, for this, the owners of vases will take at least time.

2. The second probable reason why the engine is stalling at idle - problems with throttle valve. This trouble is treated - banal.

3. If after cleaning the problem is preserved, we assume that the reason for which the motor is stalling at idle turns can be DPDZ (throttle position sensor). The problem is solved by, the procedure is not complicated and actually performing with your own hands.

There are no cases when the engine stalls on the go, as they say so much. Below will be listed the most likely and most often occurring reasons for which it can occur.

Motor stops on the go - reasons

1. Embossed fuel is the first thing that comes to the head of the majority of us, besides, it is necessary to start looking for the cause of the engine stopping on the go. You are "lucky" if it happens immediately after refueling, in this case it is safe to say that the problem is in fuel. Treated with fuel and fuel.

2. Candles. As a rule, the suspected suspicion is most often falling, after a bad fuel, of course. Here everything is simple - unscrew the candles and check their condition, if necessary.

3. Fuel filter. The order of the scored filter can cause a fuel supply interruption, as a result of which you gasut, and the engine stalls on the go. To troubleshoot a malfunction sufficient.

4. Air filter. All the same as with the fuel, if clogged, then the air does not come, therefore the fuel and air mixture comes out of convexed and the candle is simply poured. In addition, a motor shortage of air will be given, that is, power will fall, and the combustion process of the mixture in the cylinders will not be able to be carried out, in the end the motor will be stuck. To eliminate this malfunction, it is enough to replace the air filter.

5. Faulty gas station - the second "suspect". If your fuel pump is not all right, then the car will behave this way, it will be stuck on the go or the engine will not start at all. The problem is solved by checking the pump, its repair or.

6. Battery. The oxidation of battery terminals or bad contact can lead to engine stop. Check the terminals, if necessary, clean them or replace the battery.

7. If the engine strokes on the move and the generator can also become a reason for the cause. The generator failed does not charge, as a result, the side network of the car is powered exclusively from the battery, and it is not enough for a long time. As a result, you are not suspecting that the car is working on the battery, continue to move until it is completely discharged. Treated - and.

6. In advanced auto, reasons can also be with electronics and various sensors. If not strong in this and all of the above nodes and parts are normal, then it is better to turn to the specialties, and then you can replace the floor with the floor of the press ...

Why the engine stalls on the hot, Does it start a well-hot engine?

1. The first reason is. During the movement through it, a large number of air passes because of which the carburetor is seriously cooled, at the same time cools and fuel that passes through it. As a result, the temperature of the carburetor is several times lower than the motor temperature. Because of this feature, problems arise, after a long journey you are jamming the engine and makes a short stop, at this time the carburetor begins to heat the hot engine housing. The remains of gasoline in a high-temperature float chamber begin to evaporate, filling emptiness - air filter, intake manifold and actually the carburetor itself. Aerial traffic jams are formed, and there is no fuel drop in the float chamber.

The solution to the problem is quite simple - press up to half the gas pedal several times and try running the engine. By this you make a mixture poorer and release excess evaporation. It should be noted that problems with the launch of hot can also be due to a similar problem, only the fault of the fuel pump or fuel line. This, as a rule, occurs in the heat, when air traffic jams that prevent the flow of fuel in the carburetor are formed from evaporation in the fuel system or pump.

2. The second possible reason for the strange behavior of the heated engine - problems with the starter. Make sure that when you try to start the engine, the starter twists, and not just clicks or does not respond at all. If this is the case and one of the above options was confirmed. You need to check the starter. If you are on the road, then checking can be reduced to the elementary test of the starter feed wire or other visual operations. If you got home, make a detailed. In the event of a malfunction or replacement.

3. As an option, the reason when the engine does not start on a hot can be a terrestrial battery due to the above, when the generator did not give charging and the battery completely sat down.

Well, it seems to have missed anything!? Today, all, we hope the article will help, tell you the cause of the breakdown and help in solving your problem if you know other reasons, as well as how to solve them, you can add an article using the form for comments. Thanks for attention.

Carburetor, contact.

Hello everyone.

You first define with what the problem is, with fuel or ignition. And then you change everything in a row. When it stalls and impel the check if there is a spark on all candles and is there a benz in the carburetor splashing?

Most likely in the timing business - contact group, bearing, condenser ...

I had a wonderful defect - a rubber hose connecting the gas tank and fuel line. Accordingly, gasoline went, it was not, unpredictable. Fillible defect, but how he was my brains, do not convey words !!! How many times have I moved the ignition and carburetor and where I just did not stop unexpectedly! Oh, how I remember it!

Hello everyone.
Beginning to stroke the machine on the go (with a stuck transmission, usually 3-4 / during the squeezing of the clutch - during stopping - at idle).
It began with the fact that the ranks right from the exit from work. The key turned - I started - I went further. Values \u200b\u200bdid not give.
In a day or two, the "stronger" strokes (in the same place). Did not start a minute. Started - drove. After starting time, it began to stall on the go. Food 20-50, on 2-4 transmission, can stall for a second, the machine immediately wants to stop, it is impossible to unsubscribe, naturally). After a second - two from the pusher starts, goes on. The next morning got up right in the stream. I did not want at all at all. He dragged to the house, changed the slider, started and drove without problems, days 10. Then it began the same. On the first day, the ranks on the road from work, began to go, went to the next bar, a couple of times on the go - started from the pusher, the next day the stalls right in front of the house and was able to give a neutral (meters 50 remained). I especially liked when it was trying to die on the same day. Twisted as in convulsions, as if she was driving on a horse, like in the movie brake gas, indescribable sensations. From the side looked terribly, probably). Changed the slider (again yes). Made from half a turn. In a minute, stuck and that's it. Looked - the fuel filter is empty, twisted a little starter - the filter was not filled. I tried to pump up the fuel manually - there is no effect. Changed the pump, the candles (it was already it was already), Wire BB, the car went as new. After a couple of days began again. Today, there are stood from work and a couple of times in the city. Tomorrow it is stumbled in the stream ...) Stability - a sign of skill.
During all these situyevin, the car was not very frozen (at least the arrow at the beginning of the white zone).
Where to dig? I'll not have the mind (not a special repair).
Sauce, and then the city will rise because of me)
On carburetors there are two reasons for the main: 1. Clear. 2. Vacuum. There are 3 more reasons, but not the main, electromagnetic idle regulator. Mainly manifests itself at speeds up to 60km / h. Coupling, stalls at idle, stupid overclocking with twisters.

Did not read the end about the filter and the fuel pump. Dear, and you changed the mesh for a long time in the tank and the fuel pump checked himself? Membrane for example? Okay, it does not pump the manual (camshabled in the rod of storm) but from the starter for 3-5 seconds. The filter must be filled !!!
