Mustang T70 electronic throttle changed for two days, and then something went wrong. What is the reason?

The causes of electronic throttle failure are as follows:

1. The throttle position sensor is damaged, the line contact of the throttle position sensor is poor, and the initialization position of the open circuit or short circuit is incorrect. Vehicles with poor engine acceleration and unable to automatically shift will have a shift delay and a large shift impact;

2. The throttle servo motor is damaged due to excessive carbon deposition. Engine idling jitter and idling instability, low-speed flameout and poor throttle control state;

3. Poor contact, open circuit or short circuit of the throttle servo motor circuit, engine control unit failure, and engine failure light.
