How to test the throttle position by sensor?

Detection of throttle position sensor: For switching throttle position sensor, use multimeter to measure the continuity of idle switch and full load switch. For the linear variable resistance throttle position sensor, measure the resistance of its linear potentiometer. More information about the throttle position sensor is as follows: 1. Throttle position sensor is the most important sensor in automobile electronic control system, which is mainly used in engine electronic fuel injection system and electronically controlled automatic transmission system. 2. The throttle position sensor is installed at one end of the throttle shaft on the throttle body to detect or monitor the throttle opening and change speed, and convert the position signal into an electrical signal and input it to the electronic control unit. It is used to judge various working conditions of the engine, so as to control different fuel injection quantity and ignition timing.
