The VAZ-2114 should be called a relatively modern vehicle. It is equipped with a more efficient injection power plant. This system is quite simple and reliable. However, sometimes troubles happen to her, despite the fact that she practically does not need adjustment.
This circumstance often makes the owners of such a car forget about the need for regular maintenance.
Therefore, when the ECU suddenly produces certain error codes, they begin to panic.
First of all, you should know that error 0172 means that the air-fuel mixture is supplied to the engine too rich. The reasons for its occurrence on the VAZ-2114 will be discussed below.
Technical description and interpretation of error P2188
This diagnostic trouble code (DTC) is a generic powertrain code. Trouble code P2188 is considered a common code because it applies to all makes and models of vehicles. Although the specific repair steps may vary slightly depending on the model.
This code mainly concerns the value provided by the air/fuel ratio sensor, more commonly called the oxygen sensor (located in the exhaust). Which helps the vehicle's PCM (Powertrain Control Module) to control the amount of fuel injected into the engine.
Specifically, the PCM detects a rich mixture, which means there is too little air in the air/fuel ratio. This code is set for bank 1, which is the cylinder bank that includes cylinder number 1. This could be a mechanical or electrical fault, depending on the vehicle manufacturer and fuel system.
Troubleshooting steps may vary depending on the manufacturer, fuel system type, mass air flow (MAF) sensor type, and wire colors. And also a type of air/fuel/oxygen ratio sensor (AFR/O₂).

Comrade, he spoils the nervous system with caring annoyance. The malfunction indicator lights up after 2 drive cycles output by the on-board computer. I tried to change the spark plugs in the 1st and 2nd cylinders with each other, onboard Multitronics 350.
2188 with the VAZ coupe adds not only a dynamic body, 2012 the message title is not installed; good afternoon. With a short warm-up time it never popped out. Well, apparently the wire came loose due to an error.
Error 2188 VAZ
I also sprayed and there were no changes, then I went to look for the problem. We check the DMRV for vitality. The pressure regulator is also located in the tank, which is poorer.
How to Troubleshoot or Reset Trouble Code P2188
To troubleshoot and correct trouble code P2188, check the air/fuel ratio/oxygen sensor (AFR/O₂). If it consistently indicates that the engine is running rich, identify all the options that could cause the engine to run rich. These include:
- Fuel system including fuel pressure regulator.
- Fuel pressure sensor.
- Fuel injectors.
- O₂ sensor after catalytic converter.
- EVAP system including canister purge control valve.
- If the AFR/O₂ sensor indicates that the engine is running normally or even running lean, the PCM may be suspect if all other problems have been corrected.
All other codes must be diagnosed before the fault can be determined. Because problems that cause other codes to output can also cause this code to install.
Self-diagnosis of the Kalina/Priora instrument cluster
- With the ignition off, press the “Reset” button (reset daily mileage). While holding the button, turn on the ignition.
- The instrument panel will go into self-diagnosis mode, all segment positions will light up on the display, all indicators will light up, and the arrows will travel the full path.
- Using the control button on the right steering column switch, we switch between modes (self-diagnosis, firmware version, error codes).
- To reset errors, you need to be in error mode and press and hold the “Reset” button for more than 3s.
- The diagnostic mode exits automatically after inactivity for 20-30 seconds.
Decoding error codes in the dashboard:
- 2-increased voltage of the on-board network;
- 3-fuel level sensor error (if a break in the sensor circuit is detected within 20s);
- 4-error of the coolant temperature sensor (if an open circuit of the sensor is detected within 20s);
- 5-outside temperature sensor error (if there are no sensor readings within 20s, indication on the LCD is “-C”);
- 6-engine overheating (the criterion for triggering the acoustic alarm has been met);
- 7-emergency oil pressure (the criterion for triggering the acoustic alarm is met);
- 8-defect of the brake system (the criterion for triggering the acoustic alarm is met);
- The 9-battery is discharged (the criterion for triggering the acoustic alarm is met);
- E-determination of an error in a data packet stored in EEPROM.
How to reset errors on Kalina? You can reset the errors yourself using the on-board computer, or contact a service station with special diagnostic equipment.
Let us remind you that you can find detailed photo reports in the Lada Kalina repair category.

Diagnosis and problem solving
The first step is always to check the technical service bulletins (TSB) for your specific vehicle. Your problem may already be known with a known fix released by the manufacturer. This can save you time and money during diagnosis.
Next, locate the air/fuel ratio/oxygen sensor and mass air flow sensor on your specific vehicle. Once found, visually inspect the connectors and wiring. Look for scuffs, scuffs, exposed wires, burn marks, or melted plastic.
Disconnect the connectors and carefully inspect the terminals inside the connectors. See if they look rusty, burnt, or otherwise damaged. You can buy electrical contact cleaner at any parts store if you need to clean the terminals.
If this is not possible, use rubbing alcohol and a light plastic bristle brush to clean them. After that, let them air dry, take dielectric grease and coat the contacts to protect them.
If you have an OBD2 scanner, clear the diagnostic trouble codes from memory and see if the code returns. If it doesn't, it's likely a connection issue.
Sensor check
If P2188 returns, you will need to check the MAF sensor voltage signal on the PCM. Monitor the MAF sensor voltage on a scan tool.
If a scan tool is not available, check the signal from the MAF sensor using a digital volt-ohmmeter. With the sensor connected, the red wire of the voltmeter should be connected to the signal wire of the mass air flow sensor. And the black wire of the voltmeter must be grounded, that is, go to ground.
Start the engine and monitor the input signal from the mass air flow sensor. As engine speed increases, the mass air flow sensor signal should increase.
Check the manufacturer's specifications as there may be a chart telling you what the voltage should be at a given RPM. If this fails, replace the MAF sensor and try again.
Other signs
Of course, there are many reasons for excessive fuel consumption. But usually the first sign here is code P0172.
There are also a number of other signs of a problem:
- Loud pops are heard from the muffler;
- the smoke coming out of the chimney is black or dark gray;
- power is lost.
Noisy exhaust occurs more often at high speeds. The reason is that the fuel does not burn completely and is therefore discharged along with the gases to the outside. However, in its path there is a muffler that does not allow fuel to pass through, so it accumulates in it and explodes when it reaches a critical mass. As a result, there is a risk of destruction of the muffler itself or the resonators.
Blackish smoke comes out due to the fact that the combustion of gasoline residues occurs in the exhaust system, where the products formed during ignition are not filtered.
The loss of power is due to slow and incomplete combustion of fuel. As a result, it literally floods the candles, which leads to the loss of spark and, accordingly, to an even worse situation. In this situation, the piston does not receive a normal push and a decrease in power occurs. Sometimes this indicator is restored for some time after the car is driven at high speed, but usually the improvement does not last long.
Under such circumstances, gasoline consumption cannot but increase. The presence of a malfunction in the system does not prevent fuel from flowing into the engine, but it is used there with very low efficiency. A significant part of it is simply thrown into the wind, and in the literal sense.
On which cars is this problem most common?
The problem with code P2188 can occur on different machines, but there are always statistics on which brands this error occurs more often. Here is a list of some of them:
- Audi (Audi a4)

Why is error 8 associated with brake system problems?
Some car enthusiasts misinterpret error message 8, believing that they need to check the brake system. This is due to the fact that on VAZ cars this fault number indicates insufficient brake fluid level.
The Chevrolet Niva's on-board computer uses different designations, so you should not interpret them in the same way as in the VAZ. If you doubt the condition of the brake system, you can check it during the repair process. First of all, pay attention to the brake fluid level, and then check the pads.
Reasons for the appearance of symptoms of error P2135 on the Lada Granta
On different cars, with different numbers of sensors and different control units, the reasons may be slightly different. Although in almost any case, an intelligent diagnostician will first of all consider this number of reasons:
Electronic throttle valve circuit
In relation to the Lada Granta, we can safely consider problems with angle sensors or damage to the ECU, oxidation of contacts, as well as failures in the module firmware. However, if error P2135 on a Lada Granta appears in the company of codes P012%, P022%, P1538, where % is any number, you can safely blame the throttle assembly.
