After changing the water tank, the throttle is broken again?

The cause of electronic throttle failure is.

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.

5, electronic throttle fault solution is.

6. Remove the throttle valve, clean it thoroughly and re-match.

7. Replace the faulty line or faulty sensor of the sensor. Electronic throttle is an important control part of automobile engine, which consists of engine, speed sensor and throttle. The electronic throttle control system can accurately control the throttle opening, improve fuel economy and reduce emissions, realize the integration of idle speed control, cruise control and vehicle stability control, and simplify the control system structure.
