What is the fault of throttle position sensor of Nissan Beiqi Wangwei Toure?

Toler throttle position sensor is faulty, idle switch is short-circuited or open-circuited, throttle position sensor is not installed correctly, and the output signal of throttle position sensor is interrupted intermittently. Throttle position sensor, also known as throttle opening sensor or throttle switch, is a device for detecting engine state.

The throttle position sensor is also called throttle opening sensor or throttle switch. Its main function is to detect whether the engine is idling or loading, accelerating or decelerating.

The throttle position sensor is essentially a variable resistor and several switches, which are installed on the throttle body. The rotating shaft of the resistor is linked with the throttle valve, and there are two types: full open contact and idle contact. When the throttle is in the idle position, the idle contact is closed and the idle state 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; According to the increase or decrease rate of signal voltage in a certain period of time, it is identified whether to accelerate or decelerate. According to these working conditions, the computer corrects the fuel injection quantity or controls the fuel cut-off.
