my speedometer stopped working how do i fix it
Common failure forms:
1.The connections on both sides of the odometer's flexible shaft are prone to wear and tear;
2.The occasional failure of the speed sensor causes the signal to be sometimes absent, and the poor connection between the line and the combination meter will also cause the speedometer to indicate good or bad. . If it is broken, check and repair it. If it doesn't work, it has to be replaced;
3.The signal collection methods of the speedometer are different for different models. The common odometer flexible shaft is connected from the gearbox to the speedometer, commonly known as mechanical;
4.Installed on the gearbox There are speed sensors that send a signal to the speedometer over a wire. The ABS or ESP computer transmits the vehicle speed information to the combination instrument through the network to indicate the vehicle speed.
How to fix it:
1.Check and replace the odometer sensor without moving the car speedometer. The sensor is located on the gearbox housing. If the replacement of the sensor fails to solve the problem, consider the failure of the instrument;
2. Failure with vehicle speed sensor and sensor driving mechanism; Speedometer failure (speedometer) failure;
3. The wire speed or mechanism connecting the sensor and the speedometer fails.
The vehicle's speedometer will also display an indicator light to alert the owner. The indicator light has three colors: red, yellow, and green. When the red indicator light is on, it means that there is a serious fault in the vehicle, and the owner cannot continue to drive. When the yellow indicator light is on, it means that there is a fault in the vehicle, which is not as serious as the red indicator light. You can continue to drive, but it must be repaired as soon as possible. Don't worry when the green light is on, it means the function is working normally. When driving a vehicle, it is a very distressing thing for car owners when encountering the situation that the speedometer will move for a while. If there is a problem with the speedometer, you will not be able to clearly know the speed of your vehicle. If there is no navigation, you will not even know the speed. It is possible that your vehicle has violated regulations several times. Most of the reasons for such a situation are that the vehicle speed sensor is damaged, resulting in the inability to transmit the correct speed to the on-board computer, or it may be because the sensor plug is in poor contact. The failure of the sensor drive mechanism and the lack of fault codes in the vehicle's wheel speed sensor and ABS control unit system are also one of the reasons why the speedometer moves and does not move for a while.
