What is the performance of the damaged throttle position sensor?

Damage to the throttle position sensor includes engine jitter and so on. The following describes the damage performance of the throttle position sensor: 1. Unstable idle speed: Damage to the throttle position sensor will cause engine jitter and unstable idle speed. The most obvious symptom is that when the engine is unstable, it will feel weak or unable to get on the speed. 2. Can't start the car: The main function of the throttle position sensor is to detect whether the engine is in idle state or load state, acceleration state or deceleration state. Serious damage may cause the engine to fail to start.
