What is the principle of the throttle position sensor?

[EmilyRose]

The principle of the throttle position sensor is: The throttle position sensor is essentially a sliding potentiometer. When the accelerator pedal is pressed, the idle signal line disconnects, and the sliding potentiometer rotates accordingly. The computer detects the voltage value, and the resulting data is compared and analyzed by the computer to control the basic fuel injection quantity. The function of the throttle position sensor's resistor is to convert the position or opening of the throttle into a voltage signal, which is transmitted to the electronic control unit (ECU). The ECU uses this as a basis to determine the engine's operating conditions, thereby achieving fuel injection control under different throttle openings. There are three types of throttle position sensors: linear, switch-type, and comprehensive. Over time, the throttle is prone to carbon buildup. When cleaning, the electronic throttle can be removed to clean the carbon deposits, but care should be taken not to damage the electronic components on the throttle during cleaning.
