What is the cause of electronic throttle failure?

Fault phenomenon, the engine fault indicator light is on when the vehicle is driving, there is no acceleration force, and the engine shakes violently when parking. Cause of electronic throttle failure: 1. Operating the throttle opening can control the flow of combustible mixture, change the engine speed and power, and meet the needs of automobile driving; 2. The driver controls the throttle opening by operating the accelerator pedal. There are two ways to connect the accelerator pedal and throttle: rigid connection and flexible connection; 3. Because the traditional accelerator adopts the rigid connection mode that the accelerator pedal is connected with the accelerator through a pull rod or a cable, the opening of the accelerator completely depends on the position of the accelerator pedal, that is, the driver's operation intention; 4. But from the point of power and economy, the engine is not always in the best working condition, and the driver's misoperation also brings danger to safety; 5. The application of this traditional throttle is limited and lacks accuracy. With the rapid development of automotive electronic technology, Electronic Throttle (ETCS) came into being.
