Engine malfunction lights: causes and consequences. The battery light burns on the panel - the search for the causes and ways to solve this problem of the reasons why the indicator light can light up

If the engine lamp is burning on the VAZ 2110, then many reasons can be facilitated. We will look at our article, why the engine light bulb is burning on the VAZ 2110 and what needs to be done in this case.

What is this light bulb

Modern cars imagine without special sensors are simply impossible. They are indicating about the appearance of problems and various problems.
If earlier the owner of the car was to independently, so to say "manually" to detect faults, today it is not. Electronics all worries took over and on VAZ 2110 such sensors are quite a lot.
Check Engine - this is a special lamp that usually glows yellow And on which the driver determines the operation of the car engine. In normal mode, this lamp lights up for a few seconds and immediately goes out as soon as the engine is gaining momentum.
What to do when the light bulb burns and does not go out, even during the movement of the car?

Note. As soon as the VAZ 2110 owner finds that the engine lamp burns constantly and does not go out, it should immediately drive up to the maintenance station if it is nearby. If not, the motor must be drowning and cause a tow truck, as you can simply destroy the motor.

Let us return to the beginning during the period of the 90s, when car owners knew that this sensor or lamp was in a simple, can only report only on failures in the operation of the carburetor or the insufficient amount of oil in the engine.
Today, the situation is rooted and if the lamp does not cease burn, then perhaps anything: the wrong engine speed, ignition problems, problems with automatic transmission, etc. In a word, today many parameters are monitored by this sensor.

The reasons

Consider the most famous.

Butter

• The insufficient amount of lubricant in the engine is the most pronounced reason that does not know about, except that the most far from the technique is a person.

• The car must urgently stop and listen to the engine. Need to be able to determine whether there are extraneous noises. In addition, it is possible to see visually, there are no damage to the hull or inclination.
• If the above-described moments were found, then they should be immediately eliminated, in a hundred or in its own garage.

Embossed fuel

• Yes, do not be surprised. It is the quality of fuel causing today, to put it mildly, big doubts, the cause number one. Due to the diluted fuel, the Nagar accumulates. As a result, candles or one of them are not able to submit a normal spark. The engine begins to "troit" and the sensor does not cease to beat the alarm.
• Treatment In this case, only one thing: drain the dirty fuel from the tank into some container (hereinafter, this seminension can be used as detergent For spare parts) and pour new on the proven tanner.

Candles

• Spark plugs themselves may be faulty.
• Solving this problem is very simple: you need to check all the candles and replace old.
• Spark plugs, these are the main components intended for ignition fuel mixes. If they are faulty, the spark is applied incorrectly.

Council. It is possible to determine the defective candles in the process of movement of the VAZ 2110. During the acceleration of the car, especially from the place, small shoes are noticeable. Note. It is necessary to monitor the gap of the candles between the electrode, which should not exceed 1.3 mm.

Coil

• The lamp may indicate problems in the ignition coil.
• It is necessary to check whether the reel gives the reel, whether the contacts have not weakened, check the resistance at the outputs. Spark scatter also should not exceed 1-4 and 2-3.

Oxygen regulator

• It is often the cause of the engine light bulb.
• Check this sensor is easy and in case of its malfunction, you need to put a new one, and the old throw.

Note. If you do not replace this sensor, which is known, is an oxygen regulator in the car and part of the system of working out exhaust gasesThere will be problems with fuel consumption.
The malfunction of this sensor itself means that the on-board computer receives incorrect data, which will significantly increase not only the consumption of fuel, but will significantly reduce the engine power.

• The reason that it comes to disrepair can be considered that this sensor is covered with a layer of spent oil. The same, in turn, reduces the accuracy of the regulator indicators.

• If you don't change this sensor for a long time, it can lead to additional problems. May fail (just burst) Catalyst VAZ 2110. And this threatens with expensive repair.

Catalyst

• There can also be a reason for sunbathing Check Engine.
• Solution One: Replace the catalyst, of course, before checking it.

Note. This element helps to make exhaust exhaust gases are environmentally friendly. This is a prerequisite recent years. The catalyst is responsible for processing carbon monoxide and other harmful substances In harmless compounds.

• If the catalyst fails, then it is possible to notice this not only when the engine icon appears, but also long before. For example, if the power power aggregate VAZ 2110 drops 2 times, it may indicate a malfunction. In addition, the damaged catalyst will not give the car well to accelerate.

Note. Usually the catalyst fails if the car owner regularly conducts that. Particular attention to the owner must pay the oxygen sensor and to replace faulty in time so that the problem does not shift on the catalyst. In addition, it is necessary to monitor the ignition candles, which, after the expiration of their operation, need to be replaced.

Injectors

• If a sensor Check. Engine lights up due to nozzles, they will need to be cleaned or replaced.

Fuel pump or filter

• The light can light up due to faulty.
• Treatment implies the following list of actions: the pressure in the ramp is measured. The value should not be below the three atmospheres.

• In addition, you need to check the grid, the filter of the pump and try to clean it.

Tank cap

• Yes it is. It would seem that such a slight component like a lid may cause a motor light bulb.
  The fact is that such a lid violates the tightness of the entire system. So the engine icon appears.

• It is clear that the utmostity of the whole fuel system leads to an increase in the car. It immediately reacts to the diagnosis of VAZ 2110, issuing an engine error through the light bulb.
• In this case, the solution to the problem is reduced to checking the lid and its tightness. If it has cracks, it is better to replace it with a new one.

Mass flow regulator

• As mentioned above, the modern modification of the VAZ 2110 is endowed with a variety of different sensors, one of which is this one. It is responsible for supplying the required amount of air into a mixture of gasoline to create optimal fuel ignition.

• This sensor constantly reports on-board computer How much air is served.
• If the sensor is faulty, the fuel consumption increases, the engine power is reduced.

Note. If this sensor malfunction in the cold season, the car will be difficult to start.

• The reason for the failure of this regulator can be called an incorrect installation.
• With a broken sensor you can go for a long timeBut the fuel consumption will constantly increase.
• Replacing the regulator usually does not require high tools. And you can replace with your own hands.

High voltage wires

• Also known I. frequent cause light bulb.
• The solution is the same as in previous cases: checking and replacement.

Note. High voltage wires They can cause a number of special problems for the motorist, the owner of the VAZ 2110, so this component is given a separate chapter.

Check:

• We must pour into the pan of water. The dishes must be made of stainless steel.
• Add some salt there (approximately a tablespoon).
• Take a megommeter. Lower the wires into this water so that the ends are on the surface of the liquid.
• Connect the device to the first tip using the clamp for this operation.
• The second clamp is cling to dishes with water, where they are the wires themselves.

Note. Isolation is considered normal (with the value of resistance more than megoma) in 500 com or more. If the value below - the wires must be replaced, as they skip the current.

The above causes of lightbulb the most common. Inspection and replacement of damaged parts can be carried out with your own hands, thereby saving the price for services in a hundred.
The main thing is to do everything according to the instructions, studying in the process of photos and video materials.

Hello, dear car enthusiasts! Probably many of you, while driving your car, a lot spoiled a mood: it is tanning, then coming down, and then the burning (without any explicit reason) "eternal fire" Light bulb Check Engine.

What is wrong? The answer to the question - why the injector's light is burning, even many autogur will not be able to immediately give. Let's try to dig in the structural principle of malfunction.

The electronic control unit (ECU) of your car performs control over the engine through the sensor system. If the light was caught fire, then this means that one or more sensor parameters were failed, which and accordingly reacts the ECU.

Consider the functions assigned to the injector sensors. Knowing about what the sensors respond is somewhat easier to judge the behavior of their car and draw conclusions: either to eliminate the malfunction itself, or contact the car service for.

Injector Light Bulb: What Sensors say

The crankshaft sensor - determines the speed of its rotation, position, and, consequently, the location of the pistons in the cylinder. Works sensor based on electromagnetic induction.

If an injector is burning due to the triggering of the crankshaft sensor, the consequences of ignoring can be as follows: the operation of the motor on idling It will be unstable, and when the sensor is output, the engine can stumble and will not start at all.

The injector light is burning due to the control of gas distribution control in each engine cylinder. In this case, the ECU moves from phase injection to the backup - the so-called pair-parallel mode.

The principle of operation of the sensor is based on the Hall effect, the sensor is located on the front of the block from the input manifold. The characteristic features of the malfunction are to increase fuel consumption and unsure start the engine.

If the injector icon is burning due to sensor indicators throttle valveThat characterizes factor factor is the specific sound of the engine detonation ring. The sound becomes most noticeable when resetting revolutions during acceleration. As a result, the fuel consumption increases and the power decreases, since the engine must constantly work at low angles with a ignition advance.

The injector indicator is on due to the air sensor indicators, which is responsible for estimating the filling of the cylinders. Characteristic features Faults, as a rule, are an increase in idle speed (1500-3000 revolutions per minute). Also, when the gas pedal is released, the turnoves decrease slowly or do not decrease at all without additional relocation. In addition, there are characteristic jerks when the car is accelerated.

If the injector lights caught fire due to the indicators of the absolute pressure sensor, which responds to its change in the inlet path, then the engine is characterized by a factor on too poor or rich fuel mixture. As a consequence, the "immumbling" exhaust will be observed, skipping the ignition at idle, and there will also be problems with the joy of the motor.

The injector indicator is burning due to the temperature sensor indicators, the purpose of which: evaluate the thermal state of the engine. In this case, the ECU will select the backup mode, which implies the inclusion of the cooling fan and actuate high idling. With the sensor failure, there is observed engine launch and an increase in fuel consumption.

Speed \u200b\u200bsensor - intended to estimate the speed of movement. With its incorrect work, the unstable operation of the motor is observed, and with a sharp dropping load, the motor stalls. There is also a degraded speaker, and the route computer and electronic speedometer Give false testimony.

Oxygen sensor - the amount of oxygen in exhaust gases is estimated. The characteristic factors in its malfunction are the appearance of periodic oscillations when idling and increased fuel consumption.

In addition to the reasons listed, there may be mechanical damage to the chain (cluster, closure), a breakdown or skipping of the gas distribution mechanism, moisture, overheating, etc.

If the injector is burning, then the question "why?", The answer is exactly the entire error code that establishes the cause in seconds. Naturally, we need a MotorTester or a specialized computer diagnostic program.

Hello. If on your car VAZ 2109 -2114, on a running engine, a battery charge light is burning or lights up and goes out when the revolutions is set, then this article will be useful for you. The bulb should go out immediately after starting the engine. Below, I will tell you in detail about the causes of this malfunction and the ways to eliminate it.

Why the battery icon on the instrument panel of VAZ 2109 -2114 is burning.

If you explain the cause of this malfunction in a nutshell - the battery light is lit when the generator does not charge on the battery or in this chain there is a break (for example, the fuse burned). The words of all reasons due to which the light lights up:

1. Blocked the fuse in the mounting unit (F16).
2. The terminals were oxidized on the battery.
3. The generator belt is torn or slipping.
4. Stick brushes.
5. Faulty relay - regulator.
6. Sample diode bridge.
7. Open or closure in the stator or generator rotor.
8. Open the minor wire feeding the instrument panel (The generator is not with what).

Search for the causes on which the light is burning.

If you see that the charging light is burning 2114 - 2109 burns, then boldly open the hood and see if the generator drive belt did not fly. Also, the belt should not publish outsiders. Checking the belt, moving on, open the lid mounting block and check whether the fuse f16. (on the lid there is a numbering of all fuses). Fuse huff? If yes - moving on.

The presence of a multimeter will be a big plus. We check the multimeter voltage on the terminals of the battery - it should be equal to 14.4V (There are small deviations in one tenth volt).If the voltage complies with the standard, then you most likely have a minor wire feeding the instrument panel, otherwise measured the voltage between plus terminal Generator and mass. It should also be equal to 14.4V. If so, then the batteries or rings that dress on the terminals are most likely oxidized. Clean them to shine.

There is no 14B at the generator outlet - it means it will have to remove it because it does not charge. The culprit can be:

• Brushes.
• The relay is the regulator.
• Diode bridge.
• Stator or rotor winding.

The light lights up at idle and then goes out.

A separate description requires a problem when the light lights up or dimly shines at idle and goes off with a set of revolutions. In such cases, there can be only two reasons:

1. Faulty relay - regulator.
2. Slises the generator belt.

I hope this article helped you understand the reasons why the battery light on VAZ 2109 - 2114 cars lights up.

Leave your questions and comments in the comments, I will answer them!

Engine lubrication system internal combustion Four basic functions performs: reduces friction force between the conjugate elements of the power unit, cools them, protects against corrosion and clears from fuel combustion products and wear. To perform these functions in the engine, a certain oil pressure is maintained. Insufficient or overpressure will lead to fast wear and the destruction of rubbing parts. Pressure control is carried out using a special sensor and indicator (test lamp on the dashboard). We will tell when this indicator lights up and what actions should be executed by car owner.

How does oil pressure indicator in VAZ 2114/15

The inspection lamp of the oil pressure indicator in VAZ 2114/15 cars is located in the lower left corner of the dashboard and has an oil form. In the usual mode, it lights up for a few seconds when the engine is started and goes out. The lamp is an indicator of the oil pressure sensor with which it is connected through the electronic unit Engine control. The sensor is set at the top of the cylinder head (from the back of the motor). Its main element is the membrane. When pressure changes, it is bent, closure and blur contacts. When the ignition is turned on, the pressure is low, since the engine does not work yet. Light bulb lights up. After launching the power unit, an oil pump, pumping lubricant begins to operate. The pressure is growing, the membrane is strung out and opened contacts. Light bulb goes out.

The burning oil pressure light can indicate malfunctions in the engine lubrication system

The reasons why light bulb indicator can light up

The light bulb may light up both while driving and on idling. Before making assumption about the causes possible faultsIt should be observed for the behavior of the bulb. If it lights up periodically and only while driving, the problem is to search in the sensor wiring. If the lamp lights up when the engine is idling at idle and does not go out, the reason for this may be:

• failed pressure sensor;
• low oil level;
• too liquid (not appropriate class or spent its resource) oil;
• malfunction of the oil pump;
• oil filter wear;
• pollution of the oil grid;
• crankshaft liners wear.

Consider each of the specified situations.

Sensor wiring

The flashing of the light bulb during movement may be due to damage to the insulation of the sensor wire. The wire under the action of vibration closes on the "mass" of the car, which causes the sensor to work. A similar problem is eliminated by a thorough inspection of wiring and replacing the damaged area.

One of the reasons for the lighting of the light bulb may be damage to the pressure sensor wiring

Sensor

In VAZ 2114/15 cars, the oil pressure sensor often fails. Most often it is he who causes constant burning of the lamp of the indicator. Check for its health is independently impossible. Usually buy and install a new sensor.

Faulty pressure sensor VAZ 2114/15 often causes the oil pressure lamp lighting

Level and quality lubrication

If the indicator light is continuously on, check the oil level in the crankcase pallet. This is done by a special dipstick on a cold engine. If the level turned out to be below the minimum permissible, the substance should be addressed and watch the behavior of the light bulb. If she went out, the problem was precisely in the lack of lubricant.

Another cause of the burning of the light bulb may be too liquid oil consistency. The fact is that the viscosity of the oil decreases with each kilometer traveled. If the car passed more than 10 thousand km without replacing the oil, the oil pump, calculated on a certain viscosity of the lubricant, will not be able to create the necessary pressure. In such cases, the light lights up only when driving the engine to operating temperature. This is due to a decrease in the viscosity of the oil under the action of heat.

The viscosity of the oil over time decreases, due to which pressure drops in the system

This problem is solved simple oil replacement. If the indicator continues to burn, the troubleshooting should be continued.

Pressure measurement

To measure the magnitude of the oil pressure in the system, a liquid pressure gauge is used. His hose nozzle is screwed instead of a pressure sensor. First, the pressure is measured at idling the engine of the heated engine. Normal is the pressure of 1.5 to 2 bar. Then repeat measurements on high revolutions (5000-5500 rpm). In this case, it must be at least 4.5 bar.

If the pressure gauge showed values \u200b\u200bbelow the specified, check the oil pump, since it is it that creates pressure in the system. Continue to exploit the car in this case is not recommended.

The main malfunctions of the oil pump - wear of its elements and the "sticking" of the reduction valve in the open position. In this case, the easiest way to replace the pump is complete. You can do it both independently and on the car service.

Oil pressure measuring liquid pressure gauge

Filter

If the oil pressure is normal, check oil filter. Here problems can be caused by wear or incorrect installation The filter element, as well as using the filter not provided by the engine design. The fact is that when the engine is stopped, it is necessary that some amount of oil be sure to remain in the filter. In all the cases, the lubricant will flush into the Carter, which, in turn, will cause the effect of "oil starvation".

Replace the oil filter yourself. At the same time B. new filter To avoid "oil starvation", pour a small amount of fresh oil.

When replacing a new filter, it is necessary to fill a little fresh oil.

Masbandryman

The oil worker is a device designed to select the oil from the crankcase pallet and feed it into the pump. In order for wear products to do not fall into the lubrication system, the oil worker is equipped with a shallow metal grid. Pollution of this grid can lead to a drop in oil pressure.

To check the serviceability of the oil worker, it is necessary to drain the oil from the system and remove the palter of the crankcase. It is quite simple to dismantle the oil worker himself. Three bolts should be turned out, which it is attached to the elements of the crankcase.

If after the inspection of the oil worker it turned out that the grid is clogged, it is necessary to clean it. To do this, soak all the device in a hot solution of any domestic cleaning agent ("Mole", "Comet", "Sillit Bang", etc.).

If all procedures performed did not bring the desired result, you should buy and install a new oil worker.

Over time, the grid of the oil worker is clogged, and the pressure in the system falls

Inserts

Oil pressure can fall and with strong wear of the liners crankshaft (indigenous, connecting rod). It is relevant for cars with big mileage. Diagnose the problem is possible only when opening the power unit. In this case, the engine overhaul is inevitable.

Reducing oil pressure in the lubrication system occurs due to wear of the crankshaft liner

To prevent problems related to the drop in oil pressure, you should follow the following recommendations:

1. Pour into the engine the oil recommended by the automaker paying attention to the class of viscosity.
2. Provide the oil and oil filter in a timely manner.
3. Do not use non-original spare parts when repaired.
4. At least once a quarter, diagnose the lubricant system with a mandatory pressure measurement.
5. When sunbathing the pressure indicator lights, do not operate the car before carrying out complete diagnostics.

Ignoring oil pressure indicator signals threatens serious consequences for car engine. Any malfunction of the lubrication system can lead to overhaul Power unit. Try to keep it in working condition and pay attention to all signals fed by the light bulb of the indicator.

Greetings you friends on the site repair cars with your own hands. When the ignition key turns on the dashboard, a number of signal lamps light up. They sign up for the health of the engine and the engine readiness to launch.

An image of the battery is applied on one of such indicators. When the ignition is turned on, it starts to be highlighted, and after the engine factory - goes out.

This signals that charging went to the battery. But what to do if this did not happen? Why is the battery charge light burn even after launch?

A bit of theory: work scheme

To solve the existing problem, you must understand the essence of the interaction of the generator vehicle and power source (AKB).

In the process of motion, the battery is in constant recharging mode with a voltage of 13.6-14.2 volts. With an increase in the revolutions, the voltage at the outlet of the generator increases. But it is unacceptable.

To limit the voltage into the rotor excitation circuit, a small regulator relay is crashed. His task is to reduce the current to a normal level (even with a substantial increase in the number of revolutions).

The result is to maintain the battery voltage at a stable level. If the battery light is burning, this indicates the absence of charging from the generator.

How does the scheme work? After turning on the ignition, the voltage through the fuse number 10 (for VAZ-2107) is supplied to the battery charge lamp.

Next, the "+ 12V" voltage passes through a diode, a built-in relay regulator (we mentioned above), brush, contact Ring and winding.

As soon as the rotor speed increases, the phase voltage increases. As a result, the voltage at the output of the battery light bulb is aligned, and it goes out. At the same time there is a charging of the battery.

Reasons for which battery charging light burns

In fact, the reasons for the battery light bulb and there is no setting. These include:

• Weakening of the belt tension to the generator, its wear or damage;
• burning fuse or deterioration in the quality of contact in the connectors of the mounting unit;
• breakdown relay controller, diode bridge, additional diodes;
• the appearance of the cliff in the excitation circuit of the generator;
• reducing the quality of contact on the terminals of the AKB or the generator output;
• wear generator brushes ;
• lack of high-quality contact of the mass of the mass.

What to do if the battery charging light is burning?

First, leave the machine and on the engine running engine, measure the voltage at the battery terminals (do not remove the clamps in any way).

If charging goes, the voltage should be at the level of 13.6-14.2 volts. In the absence of charge, the voltage level will be much lower - about 12 volts.

To resolve the problem Prepare the following tools:

• check light bulb for twelve volts,
• two screwdrivers (with flat and cruciform sting),
• multimeter,
• passatia,
• knife
• to stripping contacts, use sandpaper.

So, proceed:

1. The readings of the on-board voltmeter indicate the presence of a charge, charge warning lamp on dashboard It does not burn on the terminals of the battery about 12 volts, and the battery itself is almost discharged.

In such a situation, work out the locations of the wires on the power source itself. If these events were useless, measure the voltage level at the "30" terminal of the generator itself.

One dipped multimeter is sitting on this terminal, and the other is on the "mass". If the voltage is much higher here than on the battery, then clean up the thirtieth terminal. If necessary, replace the wire moving from the generator to the battery.

2. The voltmeter on the dashboard and the lamp show the availability of charge, but the battery is discharged.

The voltage on the battery is normal (about 14 volts). Turning on the load (for example, headlights) leads to a displacement of the charge arrow to the leftmost position.

The main reason is the weak belt tension on the generator pulley (pull the belt, and in case of damage - replace).

Such a problem can also be a breakdown of one of the diodes, as well as the breakdown of the phase winding of the stator. Disconnect the ignition and check the diodes by a multimeter. In case of breakdown, replace them.

Check the generator brushes. To do this, get them and measure the length. If it is less than five millimeters, then the brushes are better replaced.

3. When turning the key in the ignition lock, the charge warning lamp is not lit, the charge sensor does not work, there is no charging on the battery. The reason is the burning of the fuse.

His designation is F10, a nominal - 10 amp. If the installation of a new fuse did not give results, the reason should be sought in the ignition relay or the castle itself.

4. After switching on the ignition, there is no charge, all devices work, the warning light of the control does not light up.

Check is simple - remove the wiring from the Sixty-One Generator terminals and connect it directly to the "minus" (car body). If the light lights up, then the cause of the problem is a generator excitation winding.

The second option is bad contact in the connector. If there is no result after stripping, then there is a risk of burning the lamp itself.

5. When turning the key in the ignition lock, the charge lamp is lit, and after the factory continues to twist. In this case, there is no charging or appear periodically. The reason is the insufficient contact of the wire on the connector with dashboard (It can oxidize).

Finally, check the regulator relay. To do this, apply voltage from the battery. If there are 12 volts on the brushes, then the relay is properly. If not, the device is replaced.

If you have problems with charging the battery (does not go out the warning lamp or does not light up at all), then check all versions.

But, as a rule, the problem is always on the surface, and the reason is a bad contact, blown light bulb or a faulty relay controller. Good luck on the roads and of course without breakdowns.
