What is the function of automobile throttle position sensor? Where is the position of the throttle position sensor on the car? The function of automobile throttle position sensor is to detect whether the engine is in idle or load state, acceleration or deceleration state. It is essentially a variable resistor and several switches installed on the throttle body. Throttle position sensor is also called throttle opening sensor. The rotating shaft of the resistor is connected with the throttle valve and has two contacts: a fully open contact and an idle contact. When the throttle valve is in the idle position, the idle contact is closed and the idle condition signal is output to the computer. When the throttle valve is in other positions, the idle contact is opened, and voltage signals with different angles relative to the throttle valve are output, and the computer identifies the engine load according to the signal voltage value.
