speedometer not working on car
The speedometer not working on car will not affect the driving. The common reasons for the failure of the speedometer are: 1. It may be in the instrument assembly of the vehicle. There is a fault with the speedometer, which causes the pointer of the speedometer to stop rotating: 2. The wheel speed sensor of both vehicles may have a fault, which causes the speedometer to stop rotating; 3. The mileage sensor of the vehicle may have a fault, which causes the speedometer to stop rotating.
This phenomenon is caused by a problem with the speedometer sensor of the first vehicle. This is to check whether the plug of the speedometer sensor has a virtual connection? If there is no problem, replace the new speed sensor. Second, some models do not have a separate speed sensor. This is integrated with the vehicle wheel speed sensor. In this case, you need to check the wheel speed sensor in the brake system. Or is there a problem with the ABS pump? Third, this phenomenon caused by the problem of the vehicle instrument itself, check whether the vehicle odometer is displayed normally? If the odometer displays normally, this is generally a problem with the instrument, and you need to replace the instrument with a new one, or repair the instrument.
the vehicle condition may be caused by the failure of the speedometer and may be caused by vehicle speed sensor, sensor failure or poor contact.Moreover, the failure of the speed sensor will also affect the normal count of the odometer. It is recommended to check it in time. Normally, the speed sensor is located on the output shaft (second shaft) of the transmission. On the transmission housing, the position is relatively hidden. Some cars can be seen from the engine compartment, and some cars need to be lifted to see. Basically, it has no effect on the engine, but some vehicles may light the engine fault light. In the early days, the car was usually located at the transmission. The vehicle speed sensor on the output shaft of the transmission is used as a speedometer signal and outputs a signal as long as the output shaft of the transmission is rotating. The vehicle speed will be displayed, whether it is normal driving, reversing or wheel idling. Even if the speedometer of this kind of car does not display, it will not affect at all engine operation.
