What is the fault of 217, the fault code 2178 is perfectly solved

P2177 bar, the computer definition is that the mixture is too thin, check the air intake, clean the air joint door, or clean the oil circuit to solve.

Hahaha

The P217C fault code, which is applicable to all car manufacturers, means that the fuel injector group G supply voltage circuit is high.

Background: The role of the injector is to atomize the fuel and adapt it to the requirements of combustion. The working principle is that when the solenoid coil is energized, the suction force is generated, the needle valve is sucked up, the nozzle hole is opened, and the fuel is sprayed out at high speed through the annular gap between the shaft needle and the nozzle hole at the head of the needle valve, forming a fog.

The electronic control unit controls the amount of fuel injected by controlling the injector opening interval, also known as the pulse width.

After the car is troubleshooting, the fault needs to be cleared**. When clearing the fault, it must be carried out in strict accordance with the way of clearing the fault code specified by the specific model, and the fault code must not be removed by removing the negative pole of the battery and the wire. Otherwise, it is likely to cause problems in the following two situations:

First, the control computer of some models loses the "historical record", we know that the control computer of some models has an automatic memory function, after removing the negative pole of the battery, it will clear the useful data stored in the random memory engine operation, so that the car is not good for a long time after maintenance, or after driving for a period of time, it has been cleared out of the fault**; The second point may cause the loss of normal functions, such as the audio lock function is one of the very common cases, in this case, to the sound system to work normally, it is necessary to repair the sound again, this situation, it is very troublesome.

Summary. P2178 fault code handling method: clean the throttle, check the accelerator pedal sensor, fix the socket if the plug is loose, and connect the line if the line is disconnected.

P2178 fault code, applicable to all car manufacturers, means that the system (mixing ratio) is too dense when leaving idle. A system that is too thick means that the amount of fuel (relative to the air intake) is too high. Causes of failure include intake flow sensor or manifold absolute pressure (MAP) sensor failure, high fuel pressure, fuel pressure regulator failure, fuel injector failure, oxygen sensor failure, camshaft timing error, oil overfill, evaporative discharge system error, electronic control module failure, etc.

When clearing the fault**, be sure to strictly follow the clearance method of the fault code specified by the specific model, and pay attention to the fact that the negative pole of the battery cannot be removed at will to clear the fault**.

P2178 fault code handling method: clear the throttle valve, check the accelerator pedal sensor, fix the socket if the plug is loose, and connect the line if the line is disconnected. P2178 Fault Code, which applies to all automotive imitation manufacturers, means that the system (mixing ratio) is too dense when leaving idle.

A system that is too thick means that the amount of fuel (relative to the air intake) is too high. Causes of failure include intake flow sensor or manifold absolute pressure (MAP) sensor failure, high fuel pressure, fuel pressure regulator failure, fuel injector failure, oxygen sensor failure, camshaft timing error, oil overfill, evaporative discharge system error, electronic control module failure, etc. When clearing the fault, the hail elimination must be carried out in strict accordance with the clearance method of the fault code specified by the specific model, and it should be noted that the negative pole of the battery cannot be removed casually to clear the fault.

I want to ask, when I take a taxi now, I feel that the taxi is very slow, the motor turns for a while, and the car is on fire.

I guess it's caused by some carbon deposits from the throttle or injector.
