What is the principle of throttle position sensor?

The principle of the throttle position sensor is as follows: 1. The throttle position sensor is actually a sliding rheostat. When stepping on the accelerator, the idle signal line is disconnected and the sliding rheostat also rotates. The computer detects the voltage value, and the obtained data is compared and analyzed by the computer to control the basic fuel injection quantity. 2. The function of the resistor of the throttle position sensor is to convert the position or opening of the throttle into a voltage signal and transmit it to the electronic control unit, which can judge the basis of the engine working condition and realize the fuel injection control under different throttle opening. 3. There are three types of throttle position sensors: linear, switch and integrated. Throttle is easy to produce carbon deposit when it is used for a long time. When cleaning, you can remove the electronic throttle to clean the carbon deposit, but don't damage the electronic components on the throttle when cleaning.
