[VanBeau]

It is strictly forbidden to directly remove the negative ground wire to clear the fault code. The following is an introduction to the related content of the fault code: 1. Meaning: The automotive fault code indicates that the air-fuel ratio adjustment exceeds the upper limit in a closed-loop state (mainly when the MPI is in closed-loop control under low load, the adjustment has exceeded the specified range). Faults such as air leakage in the intake system, insufficient fuel pressure, poor operation of a certain cylinder, inaccurate data from the air flow meter, damaged injector, or poor operation of the ignition system may all trigger this fault code. 2. Function: During the development of vehicles, there is an increasing trend towards intelligence, mechanization, and automated control, which requires the control unit to independently assess the status of surrounding components and the environment as much as possible.
