What is the working principle of the throttle position sensor?

The working principle of throttle position sensor is sliding rheostat. Step on the accelerator, the idle signal line is disconnected, and the sliding rheostat rotates accordingly. The computer detects the voltage value, and the obtained data is compared and analyzed by the computer to control the basic fuel injection quantity. The throttle sensor is used to convert the position or opening of the throttle into a voltage signal, which is transmitted to the electronic control unit as the basis for the electronic control unit to judge the working condition of the engine, so as to realize the fuel injection control under different throttle openings. Throttle is a controllable valve that controls air to enter the engine. After the air enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, and the combustion is successful. The throttle valve is connected with the air filter and the engine block, which is called the throat of the automobile engine.
