speedometer needle not moving
1. If the vehicle speed sensor and the sensor drive mechanism fail, the speedometer will not move. Check whether the sensor can be used. If it can't be used, it can be replaced directly.
2. If the speedometer fails, it will not move. You can check the circuit.
3. If the wire speed or mechanism connecting the sensor and the speedometer fails, the speedometer will not move. Similarly, check the sensor and the speedometer to see which one is wrong. If it needs to be replaced, replace it in time.
4. The high-end vehicle may be related to the vehicle travel computer, and the diagnosis instrument can be used to detect the vehicle model.
Common causes of failure are as follows:
1. It may be that the speedometer of the instrument assembly of the vehicle has a fault, which causes the pointer of the speedometer not to rotate;
2. It may be that the wheel speed sensor of the vehicle has a fault, which causes the watch not to rotate;
3. Maybe there is a fault with the mileage sensor of the vehicle, which causes the watch to stop rotating.According to your situation, the stepping motor of the pointer of the instrument may be broken, or something on the sensor line may be broken.
