(2) The problem describes that the PSM light will light up during the normal driving of the vehicle, and then there will be idling jitter, weak acceleration, brake flameout and other phenomena. (3) Diagnosis process ① The engine fault code is P2 12 1. The signal from the throttle position sensor 1 is incorrect. According to the fault navigation, no short circuit or open circuit was found in the wiring between the engine control module and the throttle.

When checking the on-off of the accelerator grounding wire A2 and DMEB9 1, it is found that there is no problem in normal measurement, and the harness will be accidentally disconnected by shaking hard. After careful inspection, it was found that the harness had been broken.
