We remake almost all ShNivs and problems with the oil ramp and supply to the hydraulics disappear, because we have never seen a ShNiv with normally working hydraulics. When cold, with everything else in good working order, they are tripled. Replacing with new ones does not solve the problem for long. Rework requires a regulator. screws, springs for rockers and spring engagement plates, the threads in the head for hydraulics are identical to the threads on the reg. screws, no modifications. And spare parts are taken from disassembled heads - very good. cheap.

If after resetting the adapt. The engine was spinning - of course the OS for DDet will come out. And to solve the problem - a rich mixture, there is not enough data, because gasoline does not burn, maybe the explosive part, mass air flow sensor, etc.

. but the hemorrhoids are the same. as they drummed, they continue to drum.

by error 2188 we are looking for where excess fuel or its vapor may be leaking from. We check the DMRV for “liveness”. engine oil?

Flashing the ECU will help solve the problem.

Which? Of the serial ones, it seems to be the last one. And what will the re-flashing solve, if only it removes the error from the error mask, then this is not really a solution. My question initially was whether error 2188 was real. From the answers I understood that it seemed to be real, which means there are problems with the internal combustion engine.

And to solve the problem - a rich mixture, there is not enough data, because gasoline does not burn, maybe the explosive part, mass air flow sensor, etc.

by error 2188 we are looking for where excess fuel or its vapor may be leaking from. We check the DMRV for “liveness”. engine oil?

So the fact of the matter is that it is not rich, at least on a hot engine, only CH is higher than normal.

According to the ECM, everything seems to be normal, I'm sinning on the internal combustion engine. If anyone is interested, I have attached the parameters in scanmatic format.

Shniva 2123 B797+ 22YB072S Error P2188. Is this a glitch or does it show P2188 System Too Rich at Idle (Bank 1) on ODBII? After resetting the errors, the engine began to operate less stable, but there was still P0328 - high level of the DD signal. CH is about 200, the rest is normal according to the gas analyzer. According to the parameters, everything also seems to be normal. Yes, when the engine is cold there is a knocking noise, I haven’t heard it myself, but according to the description it sounds like hydraulic noise. The error is returned after two days.

Maybe I didn’t understand something. Where is everything normal? Where the recording is 6 minutes. Injection correction according to the DC, for example, hangs rigidly at 1.25 OZ clearly jumps 8-20g

Something is clearly wrong. The liner has already pointed out the main points. If everything seems fine, check again. A rich mixture of options is smaller than a poor mixture.

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).

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.

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:

1. Fuel system including fuel pressure regulator.
2. Fuel pressure sensor.
3. Fuel injectors.
4. O₂ sensor after catalytic converter.
5. EVAP system including canister purge control valve.
6. 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.

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.

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.

Self-diagnosis of the Kalina/Priora instrument cluster

1. With the ignition off, press the “Reset” button (reset daily mileage). While holding the button, turn on the ignition.
2. 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.
3. Using the control button on the right steering column switch, we switch between modes (self-diagnosis, firmware version, error codes).
4. To reset errors, you need to be in error mode and press and hold the “Reset” button for more than 3s.
5. 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.

Motor repair

A major overhaul of a VAZ 2110 engine means restoring the engine and its components to factory standards. This operation is carried out when the motor has passed its service life and there is exhaustion in the main components.

Due to the fact that the engines have been in use for a long time, some engines are 10-15 years old, a major overhaul is inevitable. So, the combustion chambers have already worn out, and the pistons have burned out from service life and mileage. In addition, engine oil for the VAZ 2110 no longer helps to maintain performance to such an extent.

So, it is worth repairing the power unit at a car service center, especially with regard to the 16-valve engine. The VAZ 2110 8-valve engine is used by most motorists in garage conditions, since it has a simple design that is similar to the Classic and Samara power units.
