The voltage of Wuling optical throttle position sensor first rises and then falls.

Are you asking why the voltage of the throttle position sensor of Wuling Light rises first and then falls?

Sensor failure, connection problems, etc.

1. Sensor failure: The throttle position sensor failed, resulting in unstable and inaccurate output voltage signal. Due to sensor aging, damage or poor contact.

2. Connection problem: There is something wrong with the connection between the sensor and the vehicle circuit, such as loose cable connection, corrosion or disconnection. Resulting in unstable or abnormal voltage signal.

3. Engine problem: The voltage change of the throttle position sensor is affected by the working state of the engine itself. Engine problems, such as insufficient fuel supply and ignition system failure, will lead to abnormal output voltage signal of throttle position sensor.
