how to fix a speedometer

2021-12-28

If the speed sensor and sensor driving mechanism fail, the speedometer fails, and the connecting wire or mechanism between the sensor and the speedometer fails, the diagnostic instrument can be used according to the vehicle model.

1:Failure of speed sensor and sensor drive mechanism
If the speed sensor and the sensor drive mechanism fail, the speedometer will not move. Check whether the sensor can be used. If you cannot use it, you can directly replace it.

2:Speedometer fault
The failure of the speedometer will also lead to immobility. You can check the circuit. If there is a problem with the circuit, you can fix it in time to solve the problem of immobility of the speedometer.

3:The sensor and the speedometer are connected to the wire speed or the mechanism is faulty
The sensor and the speedometer connection line speed or mechanism failure will also cause the speedometer to stop moving. Also check the sensor and the speedometer to see which is the problem. If you need to replace it, replace it in time.

4:Diagnostic instrument can be used for vehicle model
High-end vehicles may be related to the vehicle travel computer. The diagnostic instrument can be used to detect the vehicle model, which can easily determine the point of failure. It is often a line or program problem. Fixing the problem in time can solve this type of problem.

The car's speedometer doesn't move. Maybe the sensor has a fault and can't be repaired by itself. It's recommended to go to the 4S store or repair shop to check the fault with a computer, and then deal with it. The non movement of the vehicle speedometer may be caused by the following reasons:

1. Check the soft core of the odometer, that is, the connecting device from the transmission to the odometer. The core in the middle may be broken;

2. If it is removed and there is no damage, check the road code meter gear on the transmission to see if there is any fault. It is from vulnerable parts;

3. If not, you need to change the channel code table. It is likely that the channel code table is stuck at 99999 and cannot carry out the next cycle.
