Long-term cleaning throttle valve cannot be added with throttle valve.

This usually happens when the fault light comes on after the throttle valve is removed from the vehicle for cleaning. The reason is that the throttle position sensor circuit is not properly connected when it is put back, or the sensor signal is abnormal when the throttle valve is not fully returned. After re-checking the line in the 4s shop, the fault can be solved by initializing the throttle with the computer.
