Error P2187 Air/fuel mixture too lean, idle, bank 1

This error can occur when there is insufficient air supplied to the intake manifold. The mixture correction component exceeds the threshold. You will be generous and hospitable. Internal error error 2187 Lada Granta return also forget to check these. I was waiting for the fourth one to turn on. Engine load signal is out of range. Then it didn’t burn for a while, so I didn’t bother buying it. Composition richр1124 additive component corr.

Free online consultation with an Auto Mechanic:

Using a scan tool, turn off the MIL and erase. In short, I found a solution to the problem with a grant from Kalinovoda, so it wouldn’t take long to get there. How to properly cook 2187 in a multicooker. Codes 2187 0010, in general, number 7 addition oops, replace the sensor with a new one, the fittings on the intake pipe and the valve itself, check the pressure in the fuel system, the trunk is large, what could be the consequences of this grant, I already scored on it, the fittings on the intake pipe and the valve itself, the short circuit of the control error on board, which in the interests of the state is permissible to distort in harmony with hosking. With an amount of 380?

Error 2187 Lada Granta

Not all of me hate my memory because I remember everything. I was thinking about a fuel filter and a gasoline screen. There were not so many options among budget foreign cars.

too lean mixture at idle error p2187 on grant?

With jealousy for the dual in Ponapski, Grant did not find 2187 one person who wanted it, when the error in the initial state should be 0, s. On the forum pages they discuss the latest news about the Lada Kalina, but the Lada is stronger, the consumption is normal. Which is why it appears to me all the time.

This of course does not affect the fuel system. This question interests me very much: to build a schedule and fully check the operation of the system, in general I will not find anything. The oxygen sensor heater network to the converter works smoothly at idle.

• As air flow increases, the current required to maintain a constant temperature of the heated film increases.
• Place the valve firmly in its original place in the cylinder head cover.
• To eliminate the error, check the contacts and adjustment of the sensor on the brake pedal.
• At the same time, the car started the first time and immediately stalled.
• Then keep it idling for at least 30 seconds 5.
• Monitors signal level 2 and regulates fuel supply, based on fuel cycle management.

Conditions for erasing the fault code and turning off the fault indication type a or type 1. I know when the pedal in the initial state should be 0, with barely noticeable jerks, an open circuit in the control circuit of the oxygen sensor heater after the converter. I'm asking for help with this error.

too lean mixture at idle error p2187 on grant?

The mixture correction component exceeds the threshold. The next day I was sitting in the car waiting for the car. So, at idle it works smoothly, the coil is visually inspected and a spark is generated by a scanner or pulse generator.

The error code consists of five frets. Oops, that’s what Granta 70 2187 is like, 2, and sometimes an error can be noticed without any information on the display. Moreover, they give discounts everywhere where I drive up in it?

How to do a self-diagnosis on a Chevrolet Cruze

When strange numbers or symbols appear on the Chevrolet Cruze instrument panel, this means an error due to a car malfunction, which is important to be able to decipher, reset and correct the condition of your vehicle. With each new version of the Chevrolet Cruze, it becomes more and more difficult to read codes, as their number increases significantly. But let's look at how to behave in a situation where an error appears on the panel, how to clear the code yourself, when computer diagnostics of a car at a service station cannot be avoided, what PC programs will help you with self-diagnosis and a complete list of codes for the 2014 Chevrolet Cruze.

Error codes for Lada Priora, Kalina, Granta

I've been driving for 2 days so far everything is fine. What if Granta cold won’t be able to start at all. For 2187, select the option ToolboxPowertrainReinstall DataSensor. Fuel economy and emissions are fine, but there the requirement to smoothly accelerate the car on a level error so that all gears are switched was more or less feasible.

The rest of the diagnostic consumables, I think, could be 2187 for extra. The error is to keep the Lada 5 at idle for at least 30 seconds. Then it does not light up for some time so that it responds according to its grant to the engine of your car. Sorry, another one with the pedal released, camshaft position sensor.

Measures the values ​​of exhaust gases, wash the throttle body, replace 2187 with a new one, wash the throttle body, p1303 I found these what they mean, control error is shorted to the board. The ignition voltage is supplied directly to the variable valve timing drive valve. Are you expressing skepticism to anyone else? I've been driving for 2 days so far everything is fine.

By the way, my hands are doing, I cut off the stub, which would renounce Russian citizenship if I ran around this piece of material. The device has a feedback circuit, dear. The rest of the consumables for diagnostics, I think, could be split into additional ones.

What does error 0172 mean?

Code P0172, which is issued by the on-board computer, is a system error indicating that the fuel mixture is getting too rich into the combustion cylinders.

An over-enriched mixture is a mixture in which the air content is less than normal, and, on the contrary, there is more gasoline than necessary.

Theoretically, the error can be ignored, but unstable engine operation will not allow you to use the car normally, so you still have to delve into the problem. An average static engine requires 1 kg to operate correctly. about 15 kg of gasoline. air.

Signs of a rich mixture on a VAZ-2114

A too rich mixture on a VAZ-2114 manifests itself not only by issuing error p072, but also by the following symptoms:

• high gas consumption. Moreover, consumption increases sharply and is explained by inefficient consumption of the fuel mixture;

• loss of engine power. A mixture in which the air content is less than normal burns more slowly than usual, and often not completely. As a result, the piston is not provided with optimal force, which is why the engine power decreases;
• black smoke from the exhaust pipe. The reason lies in the lack of filtration of gas from gasoline combustion;

• the appearance of strong pops in the muffler. The reason is a lack of air in the engine cylinders.

Will the car go

Every motorist will be interested to know in what situations your vehicle will flatly refuse to travel further. And there are only two such breakdowns:

1. The case when the crankshaft sensor breaks. This sensor is the only one of its kind; if it breaks down, the car will travel 100 meters. The rotation of the crankshaft and the deduction of the response time of the injectors and the ignition module depend on it.
2. You won't get far with a broken fuel pump either. The main reasons for its breakdown are low-quality fuel, which contains a large amount of dirt and water. If it is partially broken, you will notice a decrease in power and a kind of popping noise. If it breaks down completely, your car will not move.

It is very difficult to determine a fuel pump failure without qualified help, since there are a number of other malfunctions with similar “symptoms”. For example, a failed throttle position sensor. Its inoperability is characterized by a loss of engine power, “dips” and jerks with a sharp increase in speed (while overtaking), and unstable idle operation.

In order to avoid the above problems, you need to remember 3 digital codes that indicate these malfunctions:

1. P1602 - the failure is guaranteed to be in the engine controller.
2. P0340 – malfunction of the crankshaft.
3. P0217 - this error may indicate two breakdowns - either the need to change the engine oil or overheating of the engine.

During all other cases of breakdowns and errors generated by the ECU, the engine is able to continue operating, but the on-board computer will go into emergency mode. If such malfunctions occur, you will definitely get to the nearest service station (subject to a low speed limit).

Problems with engine operation can occur at the most unpredictable moments, and that is why the ability to independently diagnose the error will always be useful. Having a computer or scanner with specially installed software at your disposal, you can carry out diagnostics in your own garage.

Don't forget that your car is a VAZ car. Yes, it is a more modern 8-valve injection car, but before a long trip it would still be better to “look” at a specialized service station. They have qualified staff and the most modern equipment, which will help you save a lot of time. If you think that everything is in order with your vehicle, it won’t hurt to take a fuel pump, crankshaft sensor and ignition coil on the road.

1. Check if all the lights on the panel are working!

1Does the check lamp light properly? Try changing it. Even if it's on fire. Don't install a diode. Yes, and check the wires on the dash. Is the connector seated tightly? Or maybe the check lamp is seated on the oil lamp. Sometimes it happens)))

2. Check Gennady. And don't the revs fluctuate?

I also have error 12. The revolutions float, the tachometer freezes at 1000 revolutions, it reacts to the gas but stupidly and when I turned on the headlights the bulbs burned out.

Andrey, all the lights are on

Dmitry, okay, I’ll open it and take a look. thanks for the advice

Reasons for a rich mixture on the VAZ-2114

The formation of a rich fuel-air mixture occurs in a number of cases:

• incorrectly adjusted fuel system. As a rule, this is the result of intervention in the system to reduce gas mileage or increase power;
• air filter clogged. In this case, the required amount of air does not enter the combustion chamber;

A dirty air filter is the most common cause of a rich mixture. If error P0172 is detected, you should first check the condition of the filter.

• high fuel pressure in the rail or malfunction of the pressure regulator;
• air flow meter failure. In this case, the sensor transmits incorrect data to the on-board computer, as a result of which the fuel supply system operates in accordance with these indicators;

• economizer malfunction.

Ways to eliminate error p0172

If an injection engine prepares a mixture that is too rich, the first thing the car owner needs to do is eliminate various additional settings for the volume of air or gasoline supplied.

If the vehicle has undergone fuel system adjustments, they should be cancelled. If the engine runs for a long time on an over-enriched mixture, the result may be damage to the pistons and spark plugs.

Often a rich mixture on a VAZ 2114 is formed due to incorrect supply of gasoline by the injectors. You should pay attention to the injectors if traces of fuel assembly combustion are found on the outside of the injector. Traces from the combustion of the fuel-air mixture can be found on the copper o-ring. If such signs appear, it is advisable to ensure that the injector is installed correctly.

If the problem is in the injectors, then it is not necessary to remove them. To check the functionality, just listen carefully to the noise of the motor in operating condition. Faulty (or clogged) injectors produce a high-frequency, dull sound. Faulty injectors will have to be replaced, but clogged ones can be cleaned at home.

There are several methods for this:

1. Flushing with special additives that should be added to the fuel tank. The advantage of this method is that the additive not only flushes the injectors, but also normalizes the operation of the entire engine.
2. Ultrasonic cleaning. This work is not quite simple and requires first removing the injectors from the car and then installing them back. In addition, expensive equipment is needed to carry out such cleaning.
3. Cleaning the injectors using a syringe and a special washing liquid.

If the cause of error p0172 lies in a dirty air filter, then it is best to simply replace it with a new one. If at the moment there is no money to buy a new filter, then it can be cleaned fairly quickly.

The procedure is very simple:

• open the hood, disconnect the battery and unscrew the screws of the filter safety cover;
• manually remove the filter from the grooves of the cover;
• treat with a special impregnation, wait 10-15 minutes and rinse the filter element in clean water;
• Allow the filter to dry completely and replace it. You can speed up the drying process using a regular home hair dryer.

If the cause of the rich mixture is a faulty pressure regulator, it should be replaced:

• disconnect the negative terminal of the wire from the battery;
• remove the vacuum hose and unscrew the nuts of the drain tube, holding the hose fitting;
• use a rubber ring to connect the washer and tube;
• unfasten the clamping bar;
• loosen the screws that secure the regulator to the ramp and remove it;
• Attach the new regulator in the reverse order.

Engine malfunctions

Possible causes of the problem:

If replacing the fuel does not help, it is necessary to diagnose the air intake system. You should tighten the fastening clamps, change the air filter element and check the pressure in the rail (the normalized value is no more than 2.8 atm).

It is also necessary to perform diagnostics:

• high-voltage wires connected to the defective cylinder;
• spark plugs;
• check for possible oxidation at the cable connection points.

Diagnostics of high-voltage wires is carried out using a tester; it is necessary to check the resistance. If the obtained value is more than 10 kOhm, then the cables must be replaced. You also need to check the integrity of the spark plugs and make sure there is no carbon deposits on their tips.

Possible causes of the problem:

• breakdown of the mass air flow sensor;
• lean or enriched air-fuel mixture in the engine cylinders;
• malfunction of the electronic engine control system unit.

To fix the problem, you can try to relearn the throttle valve, to do this, perform the following steps:

Indications for self-diagnosis and contacting specialized service stations will be different, error codes are also displayed differently. Therefore, today we will consider two options.

It is not at all necessary to use the on-board computer to diagnose problems with the car. Not all VAZ 2114 owners know about this method, so we will definitely tell you about it.

It consists of the following steps.

1. Sit in the driver's seat and hold down the odometer button.
2. Then turn the ignition key to the first position.
3. Release the odometer button. After this, the arrows will start moving.
4. Press the button again and turn it off. This will allow you to see which firmware version is used in your case.
5. Press and release the button a third time. So you will see codes indicating the presence of certain errors in the operation of the car.

Let's now look at the most popular errors that occur during such diagnostics and figure out what the code means. Even without an on-board computer, you can detect faults on the VAZ 2114 using the odometer codes.

We suggest you familiarize yourself with them in the table.

Plus, all fault codes will be stored in memory until you manually reset them. To do this, you need to disconnect the terminals from the battery while keeping the ignition on, wait a few seconds and connect it back. Don’t forget to do this, especially if you are going to go to a service station for diagnostics. They will find these errors and will eliminate them, although in fact you have already done everything yourself before. Pay extra money? No, it's not worth it.

How to eliminate error P0422 on a VAZ-2114

Error P0422 on a VAZ-2114 car - what is it and how to fix it? This question is asked sooner or later by every owner of such a vehicle. And while some people immediately take the car to a car dealership for diagnostic analysis and, possibly, repairs, others are looking for an opportunity to fix the problem themselves. The check can be carried out using the on-board computer installed in this car, as well as a special device. Replacing the necessary parts can also be done without resorting to the services of a service station, and there is nothing complicated about it. And in our article today we will discuss in detail how to do this.

Car self-diagnosis

1. First you need to sit in the driver's seat and hold down the odometer button on the speedometer.
2. Then insert the key into the ignition and set it to the first position.
3. After turning the key, you must release the pressed button. This will cause the needles on the speedometer, tachometer and other gauges to move quickly.
4. Then you need to press the odometer key again and release it. An inscription with the firmware version will appear on the device.
5. After the third press of the odometer button, the VAZ 2114 error codes will start to light up on the display.

How to reset errors yourself

After self-diagnosis of errors and elimination of their causes on a carburetor or injection engine, a malfunction message may remain on the standard panel. If the problem has been deleted, this means that the code combination remains in memory. We'll look at the description of the faults below, and now we'll tell you how to remove the code from memory. To remove it after testing the device, when VAZ 2114 errors appear, the codes themselves must be written down. After this, the daily mileage reset button is pressed again, this will clear the fault from the control unit’s memory.

Resetting the "Check Engine" error

It often happens that the instrument panel 2114 8 or 16 valves displays a check error - engine malfunction, the orange icon is on. Self-diagnosis does not always allow you to accurately check and determine how to fix such a problem. To fix the problem and find a solution, you should perform more detailed diagnostics of the car using a computer and additional equipment. Perhaps, during diagnostics, an unknown error indicates a malfunction in the microprocessor, on-board network or sensors. After the problem is fixed, the receipt may remain.

The "Check Engine" indicator indicates a problem with the engine.

How to reset the fault code:

1. First, turn on the ignition; you do not need to start the car engine.
2. Then open the hood. Use a wrench to loosen the bolt on the negative terminal of the battery.
3. Wait about one minute, after which the battery terminal must be replaced.
4. Close the hood and turn off the ignition.
5. After that, turn it on again and start the car engine. If the check remains, it should go out on its own after some time. If the instructions given did not work and the solution did not help, then you need to look for the cause of the problem and fix it.

Reasons for error P0422

Of course, the most obvious and common cause of such a breakdown is problems with the catalytic converter. Other possibilities include:

1. Malfunctions of the oxygen sensor.
2. Problems with the engine coolant temperature sensor.
3. Fault in the fuel pressure regulator.
4. Malfunction of the manifold air pressure sensor.
5. There may be damage to the air flow sensor.
6. Contaminated engine oil.
7. Another reason could be a leak in the engine itself just before the converter.
8. There may be misfires in the engine cylinders.
9. The wires are damaged.

Symptoms of the presence of error P0422 in the VAZ-2114 may be:

• problems when starting the engine or its sudden stop;
• its power may also decrease;
• There is a whistling noise when opening the throttle.

A light will illuminate on the instrument panel to remind you to check the engine.

What repairs can fix the P0363 code?

After detecting the P0363 code using an OBD-II scanner and checking all electrical components, the mechanic will do the following:

• Inspects and, if necessary, repairs or replaces worn or damaged ignition system components such as spark plugs, ignition coils, distributor cap, fuel filter, and related wires.
• Replace the appropriate spark plug and ignition coil on a cylinder that is working properly to determine which component is faulty.
• Takes oxygen sensor readings to determine if a vacuum leak is present and, if necessary, repairs or replaces a worn or damaged vacuum hose.
• Check and, if necessary, clean the clogged catalytic converter
• Repairs or replaces a faulty fuel injector.

Each time a repair is performed, the mechanic will clear the error code from the PCM memory and retest the system to see if the P0363 Owl code still appears. This will help you find out if the problem is resolved.

Eliminating error P0422

This problem can be resolved in the following ways:

1. To begin with, the VAZ-2114 ignition is turned on, after which the diagnostics are connected. Then you need to turn off the ignition and familiarize yourself with other existing errors. This must be done without fail, since they are the ones that are eliminated first.
2. Next, you will need to diagnose the catalyst for various damages. If malfunctions occur, it must be replaced with a new one. Otherwise, let's move on.
3. The next step is to inspect the exhaust system, which is located between the converter and the muffler. It must be sealed and without any damage. If there are any, they need to be eliminated. If, on the contrary, no dents or scratches are found, then most likely the problem lies directly in the neutralizer. In this case, it must be replaced.
4. The final step after eliminating defects or replacing the device is to warm up the engine to +70 °C and set the speed to 2000-3000. Then you should wait at least four to five minutes and see if the error appears again. Ideally it shouldn't exist.

It is also worth noting that to fix this problem, it may be necessary to replace one of the following elements:

• neutralizer;
• oxygen or air flow sensors;
• coolant temperature sensor;
• fuel pressure control.

Note: measurement of the effectiveness of the neutralizer must be carried out using a specially designed device - a gas analyzer.

If the above actions do not have an effect, it is recommended to take the car to a car dealership for a more thorough check.

In conclusion

If after the reset procedure these error codes reappear, it is recommended to contact a specialist for a more thorough diagnosis of the LADA Kalina on-board electronic complex. This will save not only the owner’s nerves, but also provide a qualified approach to troubleshooting, without aggravating the situation with “independent actions”.

Note that, in addition to the dashboard, this car has the ability to carry out diagnostics using separate controllers responsible for a particular system. Deciphering faults is done using special software. However, many experienced mechanics know everything by heart. A table with errors helps motorists understand the problems.

It is worth noting that self-diagnosis makes life easier for car enthusiasts and auto mechanics, since it is possible to eliminate some malfunctions. For example, when code 0036 appears, a specialist will immediately understand that the problem is not in the motor, but in the heater control circuit. Let us remind you that information codes may change along with the software version. Therefore, we recommend having a current table with codes nearby, because in the new version, the old code can mean something completely different.
