Taurus doesn't start occasionally, and the throttle won't open.

Taurus doesn't start occasionally, and the main reasons why the throttle won't open are:

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.

2. Too much carbon deposit on the throttle.

3. The throttle motor is damaged, and the circuit of the throttle servo motor is in poor contact, open circuit or short circuit.

4. Engine control unit failure.
