What is the voltage of throttle position sensor of Wuling Hong Guang?

Wuling Hong Guang throttle position sensor voltage: the voltage between 0.5 and 4.5 volts is less than 0.5 volts and greater than 4.5 volts to identify short circuit and open circuit. The throttle position sensor is also called throttle opening sensor or throttle switch. The main function is to detect whether the engine is idling or loading, accelerating or decelerating.

Throttle position sensor, also known as throttle opening sensor or throttle switch, is a device for detecting engine state. As the name implies, these signals are transmitted to the ECU electronic control unit of the automobile through the circuit, and then the ECU electronic control unit of the automobile judges how much fuel should be allocated to the fuel system through this transmitted signal.

When the throttle position sensor is damaged, there are two problems:

1. The idle speed of the car is unstable because the sensor detects the real-time condition of the engine through two contacts. Once there is a problem, the idle speed will be very unstable.

2, can't start the car, even if it is started, it will often turn off.

If you often encounter the above two situations, it means that the throttle position sensor is broken, and the owner needs to replace the sensor in time to avoid other unnecessary effects on his car.
