The voltage of Wuling Hong Guang throttle position sensor is too low, it can only run 60 yards, but it can't run after 60 yards. What's the whole thing? Please answer quickly.

Judging from the engine speed, the estimated speed is also relatively low, indicating that the signal of the throttle sensor is abnormal, and the electronic control unit can't control the oil supply normally, resulting in the engine speed not going up. First, check whether the wiring between the sensor and the connector is in poor contact, and whether the contact head of the connector is rusty or dusty. Poor contact will increase resistance and lead to voltage drop.
