What are the causes of electronic throttle failure?

[BrynleeDella]

Electronic throttle failure causes are: 1. Throttle position sensor damage, poor contact, open circuit or short circuit in throttle position sensor wiring, incorrect initialization position; 2. Excessive carbon buildup in throttle; 3. Throttle motor damage, poor contact, open circuit or short circuit in throttle servo motor wiring; 4. Engine control unit failure. Solutions for electronic throttle failure are: 1. Remove the throttle, perform thorough cleaning, then re-match; 2. Replace faulty sensor wiring or faulty sensors. The electronic throttle is an important control component of automotive engines, consisting of the engine, speed sensor, and throttle. The electronic throttle control system enables precise control of throttle opening, improving fuel economy and reducing emissions, achieving integrated idle speed control, cruise control, and vehicle stability control, while simplifying the control system structure.
