What happened when GAC Chuanqi gs4 stepped on the accelerator?

Chuanqi gs4 reports electronic throttle failure. After cleaning the throttle, the fault still exists. Check whether the throttle plug and the body ground are at 5v, and whether the resistances from pin 2 to pin 5 and pin 6 of the throttle plug are 1ω and 2ω. Check whether the line from the accelerator pedal to the engine computer is conductive. If it is normal, it is recommended to replace the accelerator pedal.
