What is the function of the throttle position sensor?

The throttle position sensor is also called throttle opening sensor or throttle switch. The function of the device is to detect the state of the engine, and its main function is to detect whether the engine is in idle working condition or load working condition, acceleration working condition or deceleration working condition. The following is more about the throttle position sensor: 1. Structure: The rotating shaft of the resistor is connected with the throttle valve. It 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 working condition signal is output to the computer; When the throttle is in other positions, the idle contact opens to output voltage signals at different angles relative to the throttle, and the computer will identify the engine load according to the signal voltage value; According to the change rate of signal voltage in a certain period of time, whether it is an acceleration state or a deceleration state is identified. 2. Impact of the fault: The fault of the throttle sensor will lead to abnormal idle running of the automobile engine (such as excessive or low idle speed, unstable idle speed and easy flameout) or abnormal acceleration of the engine (such as engine jitter during acceleration and slow acceleration response), and may also lead to intermittent jitter of the engine during operation.
