how do you fix a speedometer that doesn't work
If the speedometer of the car doesn't turn, it will directly affect our use. At this time, don't be careless, and repair and check it in time, otherwise it is likely to cause greater impact and loss. It is possible that the sensor of the car and the driving device may be faulty, or the speedometer may be faulty.
1. If the sensor of the car is damaged, it will cause the speedometer of the car to fail. At this time, we can choose to go to the repair shop or 4S shop for repair to see if there is really a failure. If yes, we should repair it in time. If not, we should go to find other parts to see if there is a problem.
2. If there is no fault with the car sensor, it is also possible that there is a problem with the driving device of the car sensor. If there is a circuit problem or poor contact with the drive device, the speedometer will not move, so it is also necessary to check the circuit problem.
3. If the speedometer itself of the car is damaged, it will certainly cause the speedometer to be unable to turn. At this time, we need to check the wiring of the speedometer and see if there is a short circuit. If there are any, we must find professional staff when we can't repair ourselves. There are certain risks and disadvantages in our own maintenance. The speedometer will reflect the current speed of the vehicle. If there is a problem, it will directly affect the driver's use. There is no clear understanding of the driving speed, so if there is a problem, it must be solved in time.
Car speedometer does not move Check the odometer sensor and replace:
1. The sensor is located on the gearbox housing. If the replacement of the sensor fails to solve the problem, then consider the failure of the instrument;
2. Failure with the vehicle speed sensor and sensor drive mechanism; failure of the speedometer (speedometer);
3. The line speed or mechanism of the connection between the sensor and the speedometer is faulty.
If the car speedometer does not move, it may be that the tachometer or sensor is faulty and needs to be replaced. Which is what you see the current speed has been reached, and the regulations require that the speedometer display is slightly higher than the actual speed. The speedometer of the car does not move, you need to check or replace the speedometer, and there may be a problem with the speed sensor that needs to be replaced; the speedometer indicates the speed of the vehicle, and it shows the instantaneous speed, which is why the pointer shakes.
