How to repair Isuzu's low throttle voltage

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.
