Reliable Japanese engines

04.04.2008

The most common and today is the most widely repaired from Japanese engines is the Toyota Engine Series 4, 5, 7 A - Fe. Even a novice mechanic, the diagnostics know about possible problems engines in this series.

I will try to highlight (assemble in a single integer) the problems of these engines. They are a bit, but they deliver a lot of trouble to their owners.

Date from the scanner:

On the scanner you can see a short, but a capacitive date consisting of 16 parameters for which you can really appreciate the operation of the main engine sensors.
Sensors:

Oxygen sensor - lambda probe

Many owners are drawn to the diagnosis due to increased fuel consumption. One of the reasons is a banal intro heater in the oxygen sensor. Error is fixed by the code control unit number 21.

The inspection of the heater can be carried out by a conventional tester on the sensor contacts (R-14 Ohm)

Fuel consumption increases due to lack of correction when warming up. You will not be able to restore the heater - only replacement will help. The cost of the new sensor is large, and the b \\ y does not make sense (the resource of their developments is great, so this is a lottery). In such a situation, as an alternative, less reliable universal NTK sensors can be installed.

The term of their work is small, and the quality leaves much to be desired, therefore such a replacement of the temporary measure, and it should be made with caution.

With a decrease in the sensitivity of the sensor, an increase in fuel consumption (by 1-3l). The performance of the sensor is checked by an oscilloscope on the block diagnostic connectoror directly on the sensor's chip (switching number).

temperature sensor

If the owner's sensor is incorrect operation, there is a lot of problems. When the sensor measuring element is cut, the control unit replaces the sensor readings and fixes its value of 80 degrees and fixes the error 22. The engine, with such a malfunction, will work in normal mode, but only until the engine is heated. As soon as the engine cools, run it is problematic without doping, due to the small opening of the injectors.

There are cases when the resistance of the sensor is chaotically changed when the engine is running on H.H. - The turnovers will swim.

This defect is easy to fix on the scanner, watching the temperature indication. On the heated engine, it should be stable and not changed chaotic values \u200b\u200bfrom 20 to 100 degrees.

With this sensor defect, "black exhaust" is possible, unstable work on H.H. and as a consequence, increased flow, as well as the impossibility of running "to hot". Only after 10 minutes of sludge. If there is no complete confidence in the proper operation of the sensor, its readings can be replaced by turning on its chain with a variable resistor 1c, or permanent 300, for further verification. By changing the sensor readings, the change in revolutions is easily controlled at different temperatures.

Position sensor throttle valve

Many cars undergoing a disassembly assembly procedure. These are the so-called "designers". When removing the engine in the field and the subsequent assembly, sensors suffer to which the engine often lean. When the TPS sensor faults, the engine stops normally throttling. The engine when the rotation set is chopped up. The machine switches incorrectly. An error 41 is fixed by the control unit. When replacing a new sensor, you must configure that the control unit correctly seen a sign of H.H., with a fully released gas pedal (closed throttle). In the absence of a sign idle move No adequate regulation of H.H. And there will be no mode of forced idling when braking the engine, which will again entail an increased fuel consumption. On the 4A engines, the 7a sensor does not require adjustment, it is installed without the possibility of rotation.
Throttle Position ...... 0%

Absolute Pressure Sensor MAP

This sensor is the most reliable, from all installed on japanese cars. The reliability is simply striking. But and his share has a lot of problems, mainly due to improper assembly.

He is either broken down by the "nipple", and then seal with glue any passage of air, or the tightness of the supply tube is disturbed.

With this break, the fuel consumption increases, the level of CO in exhaust up to 3% increases. Very easy to observe the operation of the sensor on the scanner. The INTAKE Manifold line shows the discharge in the intake manifold, which is measured by the Mar sensor. When the entry wiring, the ECU registers the error 31. At the same time, the opening time of the injectors up to 3.5-5ms is sharply incremented And engine stop.

Knock sensor

The sensor is set to register detonation stuffs (explosions) and indirectly serves as a "corrector" of the ignition advance angle. The registering element of the sensor is Punoplastin. If the sensor malfunction, or the wiring break, on the passages over 3.5-4 tons. ECU turns fixes the error 52. It becomes intimidating when acceleration.

You can check the performance by an oscilloscope, or, measuring, resistance between the sensor output and the housing (if there is resistance, the sensor requires replacement).

Crankshaft sensor

On the 7a series engines set the crankshaft sensor. An ordinary inductive sensor is similar to the ABC sensor, and practically sureless in operation. But confusions happen. With interstitious closure inside the winding, a disruption of the generation of pulses on certain revolutions occurs. This is manifested as a limit of engine speed in the range of 3.5-4 tons. Revolutions. A kind of cut-off, only on low revolutions. Detect the intersensile closure is quite difficult. The oscilloscope does not show a decrease in the amplitude of the pulses or the frequency change (during acceleration), and the tester notice the changes in the shares of Ohm is quite difficult. If the symptoms occur the revolutions limit on 3-4 thousand, simply replace the sensor on knowingly serviceable. In addition, a lot of trouble gives damage to the target crown, which damage the negligent mechanics, producing work on replacing front kettle crankshaft or timing belt. To break the trunk of the crown, and restoring them with welding, it seems only the visible absence of damage.

The crankshaft position sensor ceases to adequately read the information, the ignition advance angle begins to change chaotically, which leads to loss of power, unstable work Engine and increase fuel consumption

Injectors (nozzles)

With many years of operation, the nozzles and needles of the injectors are coated with resins and gasoline dust. All this naturally disrupts the correct spray and reduces the performance of the nozzle. With severe contamination, there is a tangible engine shaking, fuel consumption increases. Determine the accuracy really, by conducting gas analyzes, according to the testimony of oxygen in the exhaust, one can judge the correctness of the pouring. The testimony over one percent will indicate the need for washing injectors (when proper installation Timing and normal fuel pressure).

Either by installing the injectors to the stand, and checking the performance in tests. The nozzles are easy to wash the laurel, Vince, both on installations for non-bleaching, and in ultrasound.

Idling valve, IACV.

The valve is responsible for engine speed in all modes (heating, idling, load). During operation of the valve petal, the stem is contaminated and occurs. Turns hang on warming up either on H.H. (due to the wedge). Tests for changing revolutions in scanners during the diagnosis of this motor is not provided. You can estimate the performance of the valve by changing the temperature sensor readings. Enter the engine to "Cold" mode. Or, removing the winding from the valve, to twist over the valve magnet. Singing and wedge will be tangible immediately. If it is impossible to dismantle the valve winding (for example, on the GE series), it is possible to check its performance by connecting to one of the control outputs and measuring the diversity of the pulses at the same time controlling the turns of H.Kh. and changing the load on the engine. On a fully heated engine, the unit is approximately 40%, changing the load (including electrical consumers), you can estimate an adequate increase in revolutions in response to a change in duty. With a mechanical valve jamming, a smooth extension of the duty is occurring, not entailing the change in the revolutions of H.H.

You can restore the work. Cleaning the Nagar and the dirt of the carburetor cleaner when the winding is removed.

Further adjustment of the valve is to install H.Kh. On a fully heated engine, rotating winding on the mounting bolts, achieve table revs for this type car (on the tag on the hood). After setting the E1-TE1 jumper into the diagnostic shoe. On more "young" engines 4a, 7a valve has been changed. Instead of the familiar two windings in the body of the valve winding, installed a chip. Changed the nutrition of the valve and the color of the winding plastic (black). It is noiencies to measure the resistance of windings on the conclusions.

The valve is supplied and the control signal of the rectangular shape of the variable duty.

For the impossibility of removing the winding, a non-standard fastener was installed. But the problem of the wedge remained. Now, if you clean the usual cleaner, the lubricant is washed out of the bearings (the further result is predictable, the same wedge, but already due to the bearing). It is necessary to completely dismantle the valve from the throttle block and then wash the rod with petal carefully.

Ignition system. Candles.

A very large percentage of cars comes to service with problems in the ignition system. When operating on low-quality gasoline, the ignition candles suffer primarily. They are covered with a red raid (ferry). There will be no qualitative sparking with such candles. The engine will work with interruptions, with skipping, increases fuel consumption, the level of CO in the exhaust increases. Sandblasts are unable to clean such candles. Only chemistry will help (a couple of hours) or replacement. Another problem increases the gap (simple wear).

Drying rubber tips high voltage wires, Water that fell when washing the motor, which all this provoke the formation of a conductive track on rubber tips.

Because of them, sparking will not be inside the cylinder, and outside it.
When smooth throttling, the engine works stably, and with a sharp - "crusher".

With this position it is necessary to replace both the candles and wires. But sometimes (in field conditions) If the replacement is impossible, you can solve the problem with a conventional knife and a piece of sandy stone (shallow fraction). I cut a knife with a conductive path in the wire, and with a stone remove the strip from the candle ceramics.

It should be noted that it is impossible to remove the rubber band from the wire, this will lead to the complete inoperability of the cylinder.

Another problem is related to the wrong procedure for replacing candles. Wires with power are pulling out of the wells, pulling the metal tip of the occasion.

With such a wire, ignition skips and floating turns are observed. When diagnosing the ignition system, you should always check the ignition coil on the high-voltage discharge. The simplest check - on the engine running engine, see the spark on the discharge.

If the spark disappears or becomes a filamental - this indicates an intersless closure in the coil or on the problem in high-voltage wires. Cutting the wires check the test tester. Small wire 2-3k, further to an increase long 10-12.

The resistance of the closed coil can also be checked by the tester. The resistance of the secondary winding of the coil bit will be less than 12.
Next generation coils are not suffering such a few (4a.7a), their refusal is minimal. Proper cooling and wire thickness excluded this problem.
Another problem is the current seal in the distributor. Oil, falling on the sensors, corrosive insulation. And when exposed to high voltage, the slider is oxidized (covered with a green bloom). Corner zaks. All this leads to the breakdown of spar formation.

In motion there are chaotic strips (in the intake manifold, in the muffler) and crushing.

" Thin " Fault engine Toyota

On the modern engines Toyota 4a, 7a Japanese changed the firmware of the control unit (apparently for more quick warm warming engine). The change lies in the fact that the engine reaches the turns of H.X.This at a temperature of 85 degrees. Also changed the design of the engine cooling system. Now the small circle of cooling intensively passes through the block of the block (not through the nozzle behind the engine, as before). Of course, the cooling of the head became more effective, the engine in general became more efficient. But in winter, with this cooling, when moving, the temperature of the engine reaches a temperature of 75-80 degrees. And as a result, permanent warming turns (1100-1300), increased fuel consumption and nerve owners. You can fight this problem, or the engine is stronger than the engine, or by changing the resistance of the temperature sensor (deceiving the ECU).

Butter

Owners pour oil into the engine without special disclaimwithout thinking about the consequences. Few people understand that various types of oils are not compatible and for mixing form an insoluble porridge (coke), which leads to the complete destruction of the engine.

All of this plasticine cannot be washed into chemistry, it is cleaned only by mechanical way. It should be understood if the old oil is unknown, it should be used before changing. And another advice to the owners. Pay attention to the color of the oily probe handle. It yellow color. If the color of the oil in your engine darker color handles - it's time to replace, and not wait for the virtual mileage recommended by the manufacturer motor oil.

Air filter

The most inexpensive and easily accessible element - air filter. Owners very often forget about his replacement, without thinking about the likely increase in fuel consumption. Often because clogged filter The combustion chamber is very polluted with oil burnt sediments, valve, candles are strongly polluted.

Diagnosis can be mistakenly assumed that all wines siloslets Kolpacchkov, But the root cause is a scored air filter, which increases with dirt discharge in the intake manifold. Of course, in this case, the caps will also have to change.

Some owners do not even notice about living in the corpus of the air filter garage rodents. What speaks of their complete emptying to the car.

Fuel filteralso deserves attention. If it does not replace it in time (15-20 thousand run) the pump begins to work with overload, pressure drops, and as a result, the need to replace the pump.

Plastic impeller pump parts and check valve are prematurely wearing.

Pressure drops

It should be noted that the operation of the motor is possible at a pressure of up to 1.5 kg (with a standard 2.4-2.7 kg). Upon reduced pressure, there are permanent strips in the intake manifold Running problem (in terms of). The thrust is noticeably reduced. The pressure test is properly produced. (Access to the filter is not difficult). In the field, you can use the "pouring test from the return". If during the operation of the engine in 30 seconds from the gasoline, the gasoline is less than one liter flows, one can judge reduced pressure. It is possible for indirect determination of the pump performance to use an ammeter. If the current consumed by the pump is less than 4amper, then the pressure is seized.

You can measure the current on the diagnostic shoe.

When using the modern tool, the filter replacement process takes no more than half an hour. Previously, it took a lot of time. Mechanics always hoped in case they were lucky and the lower nozzle did not fit. But often it happened.

I had to break my head with a long way to hook a rolling nut of the lower fitting. And sometimes the filter replacement process turned into a "film" with the removal of the tube applying to the filter.

Today, no one is afraid of this replacement.

Control block

Until 1998 release, Control blocks did not have enough serious problems when operating.

Repairing blocks only due to" tough cakes" . It is important to note that all conclusions of the control unit are signed. Easy to find the required sensor output on the board to check, either wire transversals. Details are reliable and stable at low temperatures.
In conclusion, I would like to stop a little on gas distribution. Many owners "with hands" procedure for replacing the belt are performed independently (although it is not correct, they cannot properly tighten the crankshaft pulley). Mechanics produce a high-quality substitution for two hours (maximum) when the valve belt breaks are not found with the piston and the fatal destruction of the engine does not occur. Everything is designed to smallest things.

We tried to tell about the most frequent problems on Toyota Engine engines. The engine is very simple and reliable and subject to very tight operation on "water-iron gasolines" and dusty roads to our great and mighty homeland and the "Avosny" mentality of the owners. All mockery, he still continues to delight his reliable and stable workBy won the status of the best Japanese engine.

All the speedy identification of problems and light repair of the Toyota 4, 5, 7 A - Fe!

Motor faults and repair 5A-F / FE / FE

The Toyota 5A engine is an analogue of the motor 4a, in which the diameter of the cylinders from 81 mm to 78.7 mm is reduced, thus obtained the volume of 1,500 cc. Otherwise, we have the same 4A-F / FE / FE, with all its pros and cons. The usual civil engine, GE / GZE sports versions on the basis of 5a was not developed.

Toyota 5A engine modifications

1. 5A-F is a carburetor version, analogue 4A-F with a reduced volume. Compression ratio 9.8, Power 85 hp The engine was in production from 1987 to 1990.
2 . 5A-FE - an analogue 4a-Fe, represents a 5a-F with electronic fuel injection, compression ratio 9.6, power 105 hp The engine production was started in 1987, finished in 2006, after which production was transferred to FAW and now they are equipped with Chinese cars.
3. 5A-FHE - version with modified GBC, other camshafts, a bit changed inlet, another exhaust manifold, power increased to 120 hp. In production was from 19891 to 1999 and put on cars for the inner Japanese market.

Malfunctions and their causes

One-to-one motor design repeats the 4a motor, all those faults are currently relevant for 4a, belong to 5a: Problems with a rubber, with a lambda probe, with a motor temperature sensor, after which the engine does not start, float due to dirty damper, idling sensor Stroke and so on. There are no hydraulic components for 5a, therefore, once in 100 thousand, we carry out the procedure for adjusting the valves, after the same mileage we change the timing belt. In general, everything is standard for the series A, a complete list of engine diseases look.

Toyota 5A-F / FE / FE engine tuning

Chip tuning. Atmo. Turbo

Exactly as with in atmospheric version of the motor will not show anything supernatural. The only thing that makes sense is to settle the cylinders to a diameter of 81 mm, under the piston 4a-Fe, thereby we get a working volume of 1.6 liters and actually the 4a-Fe engine, but there is a risk to run into casting defects. You can put a straight-flow exhaust with spider 4-2-1, but this will not give anything serious.

5a-Fe turbine

Initially, this motor was developed for the most relaxed movement, no sport was envisaged, so any serious tuning would entail the replacement of the entire regular junk, it applies to the tuning and turbine as the way. The most sensible option from possible, it is to order a whale on a 4a-Fe on a small turbine and put on a standard piston, pre-putting the nozzle 360ss, the pump Valbro 255 and the forwarding release on the 51st pipe, set up on the abita. It will give it up to 140-150 hp, the resource will be much reduced. Want a resource, change the crankshaft, SPGs, saw CHC ... or Saw 4a-GE)).

Family A enters the second wave (1980 - 2000) of the Japanese Motor Building Toyota. Execution 5A has a smaller piston diameter than the previous version 4a - 78.7 mm instead of 81 mm. The engine volume decreased to 1.5 liters, power up to 105 liters. s., torque up to 143 nm. Unlike the previous series, the 5a FE engine does not have sports versions of GE, turbocharged modifications and generations with constructive changes.

Specifications 5a Fe 1.5 l / 105 liters. from.

Initially, the Toyota series of the series A is laid for reliability, high maintainability and a huge supply of spare parts. Looks like engine scheme as follows:

• R4 is a row four, cylinders are flowing inside the cast-iron case, the lubricant / cooling channels are made during casting;
• the belt is driven and the timing, and hinged equipment;
• motors are designed for C / D Class cars, Caldina / Carina / Corona 170 - 210 and Corolla / Sprinter 90 - 110 families.

Produced in Japan for domestic market And in China for all Southeast Asia. An important feature is the lack of the impact of the piston / valve when the belt drive is broken. In other words, the 5a FE motor does not oppress the valve.

In order to increase the power, electronic EFI injection is used in the design. Valves are located relative to each other at an angle of 22.3 degrees. The ignition system is first traver, then without a charge peder, two-way DIS-2.

The user manual contains a description of the parameters of the power drive, the regulations are the drawings of the main actions that make it necessary to carry out the maintenance of the motor and its overhaul.

Design features

The official manual on the atmospheric row engine 5a Fe contains a design description:

• the cast iron unit, the cylinders are crushed in the body without a sleeve, which dramatically increases maintainability and reduces the cost;
• cylinder head dual with DOHC 16V gas distribution;
• initially, the ignition system consisted of a common coil, a traver, a beam of high-voltage wires, later added the second coil according to the DIS-2 scheme;
• there are no hydrocompensators, no VVTI couplings, therefore, the requirements for the quality of oil are quite low;
• forcing is most often made by analogy with the AvtoVAZ engines in the cylinder boring;
• the overhaul is easily performed in the garages on its own;
• a feature of the design is the belt drive of one camshaft, the second gets rotation to the gear wheel from it.

The design is very simple, reliable, maintainable, highly massive.

The list of modifications of the DVS

In the 5a series, there are only three versions of engines, one of which is 5a-Fe. Two others are its modifications, respectively:

• 5a-F carburetor version was produced in the period 1987-1990, the engine had an 85 liter power. from. and the compression ratio of 9.8 units;
• in the version 5A-FHE modernization intake manifold, inside the GBC, camshafts with increased phases and lifting height of cams were installed, Motor was produced in 1991-1999, had a power of 120 liters. p. applied exclusively in the domestic market.

Accordingly, the original attachment equipment was used, not interchangeable with the basic version of 5a-Fe.

Pros and cons

An inline atmospheric device of the DVS provides a number of advantages to the owner:

• saving the operational budget - AI-92, the presence of spare parts, independent service and repair on the knee;
• resource from 350000 miles of run, even on domestic gasoline;
• the possibility of forcing to increase torque.

Disadvantages are also present, but in toyota motors They are not so much:

• adjusting thermal gaps of valves every 30000 km;
• non-discharge of piston fingers - fixed, and not floating landing;
• intensive depreciation of camshafts inside the GBC;
• ignition problems.

The main advantage is the absence of the collision of the valve and the piston in the sudden cutting of the timing drive.

List of car models in which installed

The 5a FE motor was designed, not only for specific classes C and D, but also under the families toyota cars:

• Carina - 1990 - 1992 in the Bodger AT170, 1992 - 1996 in the body AT192 and 1996 - 2001 in the body AT212;
• Corolla - 1989 - 1992 in the body AE91, 1991 - 2001 in the body AE100, 1995 - 2000 in the body AE110, Ceres 1992 - 1998 in the Bodger AE100;
• Corona - 1989 - 1992 in the Body AT170;
• Soluna - 1996 - 2003 in the Body Al50 for Southeast Asia;
• Sprinter - 1989 - 1992 in the body AE91, 1991 - 1995 in the body AE100, 1995 - 2000 in the body AE110, Marino 1992 - 1998 in the Bodger AE100;
• VIOS - 2002 - 2006 in the Body AXP42 for China;
• Tercel - 1990 - 1994 In the body of a sedan for Chile and a coupe for Canada, USA.

The manufacturer appreciated both the characteristics of the engine, and the successful design of the 5a Fe execution, so even after the Toyota ceased to install these motors, the Chinese FAW company continued their release for the FAW XIALI Weizhi's own cars.

Rules of maintenance 5a FE 1.5 l / 105 liters. from.

During operation, the 5a FE engine requires periodic care within a specific time limit:

• change the timing belt and mounted after 50,000 km;
• the developers recommended to regulate the thermal gaps of valves after 30,000 runs;
• cleaning for ventilation Carter Manufacturer is provided every 20 thousand km;
• the manufacturer recommends the replacement of engine oil and oil filter 7500 km;
• the fuel filter is enough for an average of 40,000 runs;
• on the manufacturer's recommendation, the air filter is set new each year;
• according to the date of the production of antifreeze from the plant, it is enough for two years or 40,000 km;
• in the ignition candles for the engines of the resource 20,000 mileage;
• the exhaust manifold will progrit after 60000 km.

After the forcing, the resource of the friction pairs is reduced by 20 - 30%, so consumables will have to be changed more often.

Overview of faults and ways to repair

With increasing mileage, the 5A FE motor can reveal the following problems:

Knock	1) Nagar on the valves 2) Wear piston fingers 3) wear of camshafts and their beds	1) cutting and adjusting thermal valve gaps 2) replacement of fingers 3) Replacing camshafts or CHC
Increase lubrication consumption more than 1 l / 1000 mileage	1) Outputing of the oil-grip rings 2) wear of oilmaging caps	1) Rings Replacement 2) Caps Replacement

Motor will not start	temperature sensor breakage	replacing the sensor

These faults are characteristic of the Toyota Motors.

Motor tuning options

Initially, the 5a FE engine is deformed relatively previous versionsTherefore, inexpensive mechanical tuning is possible here:

• boring cylinders up to 81 mm;
• using pistons from 4a-Fe.

In fact, the user receives the previous version of the motor with a combustion chamber of 1.6 liters. Further tuning is performed according to the classic scheme:

• grinding the channels of the intake manifold and the GBC;
• "Evil" camshafts, at least 5a FHE or with large phases;
• "Spider" on the exhaust, "cheating" instead of the second sensor CO;

Motor is household, therefore optimal option Is SWAP to the sports version of 4a GE. A little cheaper will be turbo tuning:

• ordering whale on a low-power turbine;
• installation of high-performance, type 360ss nozzles;
• straight-flowing with a cross section of 51 mm exhaust;
• using fuel pump Walbro GSS342 with a capacity of 255 l / h;
• the transition to the ABIT M11.3 software.

Upon receipt of 150 liters. from. The resource of the friction pairs and engine will noticeably decrease. To restore it, you will have to modify the head, SPG and replace the crankshaft.

Thus, the 5A-FE motor was created for two families of Toyota cars - Corolla / Sprinter and Karina / Calin C and D classes. Power drive is very reliable, economical intended for calm driving in the city cycle. The design is poorly forced, but absolutely maintainable.

Air temperature sensor on the inlet Toyota in conjunction with other controllers is used to ensure normal operation power aggregate. If a malfunction occurs in one of the regulators, it may affect the operation of the engine as a whole. The list of main sensors of Toyota cars, as well as recommendations for their replace, are given in this article.

Characteristics and features of the replacement of controllers

Consider the location, diagnostics and procedure for replacing sensors below.

Inlet air temperature

This controller is located on the inlet pipe. The diagnostic procedure of the device consists in measuring the resistance and reconciliation of these values \u200b\u200bwith the nominal, installed manufacturer. These readings can be found in the service book.

Crankshaft

DPKV is installed in front of the BC. If the device for some reason fails, the operation of the motor will be impossible, while dashboard A corresponding indicator should appear.

To diagnose and replace DPKV, follow these steps:

1. Turn off the battery and dismantle the motor mudguards.
2. Next, you will need to turn off the PCP power plug.
3. With the help of appropriate wrench keys (their dimensions can be different depending on the car), unscrew the screw, locking the device, then dismantle it.
4. To diagnose the device, you need to measure the resistance parameter between the outputs on its plug. Ommeter is used for diagnostics. At air temperature of about 10-50 degrees of heat, the resistance level should be about 985-1600 ohms.
5. If values \u200b\u200bare different, this indicates the need to replace DPKV. Install the new device instead of the failed regulator, the process of further assembly is carried out in the reverse order.

Idle move

Idling sensor in Toyota Corolla 5A, Fe and models with other modifications of engines is used to stabilize idling. This controller allows for the supply of the required amount of air, which allows you to stabilize the work of the idling.

To check the idle sensor, follow these steps:

1. When the driver turns off the ignition, the RHX should publish a characteristic click.
2. Disconnect the connector of the regulator, after which the voltage to contact B1 and B2 will be supplied with the jumper. Then it is necessary to connect with the mass of contacts S1 and S2, and then - S3 and S4. At this point, the PCH plunger must be advanced. In the event that the regulator does not turn on, this indicates its malfunction.

To replace the idle sensor, follow these steps:

1. In the event that access to bolts that fix the knob is hampered, it will be necessary to remove the flap housing.
2. Remove the bolts that lock the device to the body of the damper itself, after which dismantle the RCX.
3. By installing a new device, do not forget to put a new seal (the author of the video is Alexander Dmitriev).

Detonation

The detonation sensor is mounted on a special screw, screwed into the wall of the motor cylinders, from above. If the device breaks, the error is written to the control unit, resulting in on-board computer Activates a motorcycle motor control program.

To check and replace the detonation sensor, you will need to do the following:

1. First, dismantling the decorative lining of the motor.
2. Next, you need to turn off the negative cable from the battery.
3. Remove the inlet motor motor. At this stage, problems may occur, especially if you have never encountered such a task.
4. Next, you will need to compress the mount and disconnect the plug from the regulator with the suspended wires.
5. Now you can unscrew the screw that fixes the detonation sensor, and dismantle the device.
6. To make it diagnostics, it will be necessary to measure the resistance parameter between its outputs. On average, at a temperature of about 20 degrees of heat, resistance should be about 120-180 com. If the values \u200b\u200bdiffer, the device is replaced, this procedure is carried out in the reverse order.

Oil pressure

This device is designed to detect low or high pressure motor fluid In the engine. As a rule, reduced pressure indicates a lack of consumables In the motor. Therefore, when the corresponding indicator appears on the instrument panel, check the level of the engine fluid, and if it is normal to replace. The device is located in the wall cover of the timing chain.

How to change it:

1. To prevent closures in electrocups, disconnect the battery.
2. Then find the DDM itself, then disconnect the connected connector from it.
3. Using a wrench on 24, you will need to unscrew the controller from the cylinder block.
4. After dismantling DDM, set the new controller on its place, the installation procedure is carried out in the reverse order (author of the video - Avto MAN channel).

Tire pressure

Tire pressure controller is used to warn the driver about the possible sloping of the wheels. On the dashboard there is an appropriate indicator that lights up if the pressure in the wheels does not correspond to the nominal value. Before replacing the controller, you need to make sure that the problem lies in it. To do this, measure the pressure in the tires and if it matches the normal value, then you can proceed.

The sensor is equipped with each wheel:

1. First you need to weaken the bolts that fasten the wheel, while completely unscrewing them.
2. Then put the corresponding part of the car on the jack (if the front controller changes, it is subdominated by the front, if the rear is the rear).
3. Fully unscrew the bolts that fasten the wheel, then pull it a little on yourself.
4. Remove the wheel and dismantle the rubber from it. If you have never come across such a necessity before, it is better to seek help for tireage. After disassembling rubber, you can see the pressure sensor with the nipple, through which the wheel is pumped. Remove the device and change it to the new one, while performing all actions in the reverse order.
