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).
Operating principle of the oil pressure sensor and checking it
The operating principle of the DDM is quite simple - depending on the oil pressure, the measuring membrane inside the sensor bends under the oil pressure and closes and opens the contacts. If the engine oil level drops, the contacts open accordingly and the oil pressure warning light comes on.
Before checking the sensor, make sure that:
If everything is in order with the oil level and filter, you need to check the sensor circuit and itself.
If your vehicle is equipped with an on-board computer, a P0523 (Oil Pressure Sensor High Voltage) error will appear if the ODM malfunctions. This error indicates that the sensor needs to be replaced.
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.

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.
How does the self-diagnosis complex work?
This system is self-regulated in automatic mode. Its structural composition includes several electronic devices. Based on sensor impulses, a variety of information flows into the ECU memory, among which there are faults. They are presented in the form of designated fault codes. Car manufacturers do not support the idea that owners are inclined to independently maintain electronic systems of cars, therefore they tend not to disclose the meaning of the codes. Here we can see the noble motive of the developers, because they understand that in this way scammers can take advantage of the situation and change the settings of the electronic module, for example, reduce the odometer readings before selling the Lada Kalina car, etc.
This situation forces the manufacturer and dealers to persuade owners to service the self-diagnosis system in specialized services.
A particularly important component of this system is the on-board controller. With its help, information collected from sensors is processed and displayed on the display. Lada Kalina does not have such a device, which deprives the owner of the ability to visually read information regarding breakdowns. This is where scanning equipment comes to the rescue. Thanks to it, self-diagnosis occurs.
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)
- BMW
- Cadillac
- Chery (Chery Tiggo, Fora)
- Chevrolet (Chevrolet Captiva, Cruz)
- Dodge
- Ford (Ford Mondeo, Escape)
- Geely (Gili Emgrand)

With fault code P2188, you can sometimes encounter other errors. The most common ones are: P0131, P0136, P0172, P0642, P2178, P2190, P2191.
Additional comments for troubleshooting P0523
If the Check Engine light comes on and you notice that the oil pressure is too high, this could indicate a serious problem. We should not forget that the problem may not only be a malfunction of the engine oil pressure sensor (which is often found in older cars with mileage of more than 130,000 km), but also engine damage. If error P0523 appears, it is recommended that you contact a qualified technician as soon as possible to diagnose and resolve the error in order to avoid complete engine failure.
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.
Lamps for increased visual comfort
The DRL lamp of the Lada Granta Deluxe is an ordinary halogen low beam incandescent lamp, shining white. The main disadvantage is reduced visibility in rainy weather due to the fact that white light produces much more glare from wet surfaces and raindrops than yellow light.
The following brands of high-comfort halogen lamps are most often found on sale: OSRAM, General Electric, Mayak, Philips, Narva, IPF, Hella, etc. The manufacturer recommends choosing OSRAM H4 models in Standard and Light Day modifications. The first fully complies with all norms and legal requirements for safety, illumination, geometry and accuracy of the cut-off line. Has the highest luminous intensity value. The second model differs from the first in having a significantly longer service life. In terms of luminous intensity it is slightly inferior to the Standard modification.
Replacement of low beam lamps is carried out as follows. Clear access to the left headlight unit. To do this, release the Lada air filter housing from all fasteners, disconnect the wiring harness and sensor. Then slide the filter housing up and to the left. To gain access to the right headlight, you need to remove the power unit cover. To do this, unscrew the oil filler cap and then the 4 mounting bolts. After this, pull the cover up and unclip it.
To remove the old lamp, first turn the socket counterclockwise and then carefully pull out the light source. Install the new one in the reverse order: first install the base into the groove of the cartridge, then screw the cartridge clockwise.
Please note: when replacing halogen lamps, it is not recommended to touch the bulbs with your fingers.
The fact is that fingerprints of sweat and grease on the bulbs of lighting devices reduce their service life many times over. Therefore, it is necessary to work in clean cotton gloves without rubber coating. Wipe the flasks themselves with alcohol wipes before installation.
Replacing the sensor yourself
We remove the decorative plastic protection and put it aside so that it does not interfere
Carefully squeeze the clamps and remove the block from the sensor
Using a spanner or open-end wrench set to “21”, unscrew the sensor.
Now we will examine it and diagnose it according to the points that we described above.
We screw in the new sensor, connect the wire block and start the engine. If the oil pressure light goes out, then the problem was in the sensor; if not, then you need to look for the cause further.
