What is the use of the throttle position sensor? Can the throttle position sensor be unplugged?

The throttle position sensor is located on the side of the throttle and is the "personal" doctor for the throttle. Some curious babies will ask: "Can the throttle position sensor be unplugged? If it is useless, I will unplug it, which is an eye-catcher."

Throttle sensor function

Throttle position sensor is one of the most important sensors in the automobile electronic control system. It is installed on the throttle and is mainly used to detect the change of the throttle opening. It converts the change of the throttle opening into an electrical signal and inputs it to the electronic control. oneYuanOn the ECU, the ECU determines the operating conditions of the engine according to the throttle position signal, and then the computer corrects the fuel injection volume and ignition timing based on these operating conditions.

Can the throttle position sensor be unplugged?

Can not! This will have a certain impact on the operation of the car. After the throttle position sensor is unplugged, it will not be able to detect the operating conditions of the engine, and the trip computer will not control and adjust the fuel injection volume, which will also affect the idling situation of the car. Some cars will enter the protection mode after unplugging the throttle position sensor. The computer does not allow the speed to be too fast. The fastest speed can only be maintained at 40 kilometers per hour, and some will increase fuel consumption. If the throttle position sensor fails or is damaged, it is best to replace it in time.

Symptoms of Throttle Position Sensor Damage

If the throttle position sensor is damaged, the car will experience abnormal idling (such as excessive or low idling, unstable idling, and easy stalling of idling) or abnormal engine acceleration (such as engine shaking during acceleration, slow acceleration response), etc. It may also cause intermittent jitter in the engine during operation.
