What does Wei Chai 523004 fault code mean?

Wei Chai engine fault code of Pacific Auto Network is 523004. This happens because the engine throttle of the vehicle has too much carbon deposit, so it is necessary to clean the engine throttle of the vehicle to clear this fault code. Automobile fault code is the fault code reflected by the analysis of automobile computer ECU after automobile fault occurs. General fault codes are caused by sensor faults, but some mechanical faults cannot be read by ECU.

When the automobile engine fails, the computer will display the fault code after being detected by the detection computer. Through this code, maintenance personnel can accurately find the faulty parts and then carry out maintenance.

There are two kinds of automobile fault codes: one is accidental fault.

The other is the actual failure. Under normal circumstances, accidental faults can be cleared as long as they do not appear, but if they are actual faults, they must be repaired before they can be cleared.

The meaning of automobile fault code is that the air-fuel ratio adjustment exceeds the upper limit in closed-loop state (mainly the range that MPI has exceeded when closed-loop control is low load). For example, air leakage in the intake system, insufficient fuel pressure, poor cylinder operation, inaccurate data of air flow meter, damaged fuel injector, poor ignition system operation and other faults.
