What is the cause of electronic throttle failure?

Causes of electronic throttle failure: 1, damaged throttle position sensor, poor line contact of throttle position sensor, incorrect initialization position of open circuit or short circuit; 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. The solutions to the electronic throttle fault are: 1, remove the throttle, clean it thoroughly, and then re-match; 2. 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.
