1. What is the function of the throttle position sensor? There are several kinds of throttle position sensors, the main function of which is to detect the change of throttle opening and judge the working condition of the engine. They are mainly used in the electronic fuel injection system and electronic automatic transmission system of the engine. The change of throttle opening is converted into an electrical signal and input to the electronic control unit ECU, which judges the working condition of the engine according to the throttle position signal, and then the computer corrects the fuel injection amount according to the working condition information. It is essentially a variable resistor. Throttle position sensor can be divided into linear output throttle position sensor and dry output throttle position sensor.
