As soon as the car is electrified, the throttle will automatically turn.

Throttle carbon deposit, clean the throttle. When the car is powered on, the throttle will automatically turn, because carbon deposits will be generated near the throttle when the car is in use, which will lead to incomplete throttle closing. When the vehicle is powered on, the ECM will send a signal to make the throttle perform a self-test. At this time, the throttle may rotate automatically to confirm its working state, check whether there is carbon deposit in the throttle, and then clean the throttle.
