What should I do if the throttle position sensor is damaged?

The main symptoms of automobile throttle damage are engine jitter and unstable lifting speed. After the throttle position sensor is damaged, it should be replaced in time. The following steps are to replace the throttle: 1, first unplug the circuit plug on the throttle position sensor; 2. Unscrew the two screws fixing the sensor with a short-handled Phillips screwdriver; 3. Then take out the old sensor, install the new sensor and tighten the two fixing screws; Finally, before the road test, plug in the circuit plug and start the vehicle. The reason for the failure of the throttle position sensor is as follows: 1. Due to poor contact, low voltage or non-conduction, the engine is easy to stall or start. 2. High or low output voltage caused by initial position misalignment will lead to high or low idle instability. 3. The change of coating failure resistance leads to inaccurate output voltage and poor acceleration of vehicle starting. 4. Too much carbon deposits on the throttle valve and its lax closing affect the output voltage value and flow value, resulting in inaccurate air-fuel ratio and unstable idle speed.
