What is the function of automobile throttle position sensor?

The main function of the throttle position sensor is to detect whether the engine is in idle state or load state, acceleration state or deceleration state: 1. The rotating shaft of the resistor is connected with the throttle valve, and it has two contacts: a fully open contact and an idling contact. When the throttle is in the idle position, the idle contact is closed and the idle signal is output to the computer;

2. When the throttle valve is in another position, the idle contact is opened, and a voltage signal different from the throttle valve angle is output, and the computer identifies the engine load according to the signal voltage value;

3, according to the change of signal voltage in a certain period of time to identify whether it is a rising or falling condition or a deceleration condition. According to these working conditions, the computer corrects the fuel injection quantity or controls the fuel cut-off.
