What is the insensitivity under the car tachometer?

Common reasons for failure are as follows:

1. There may be something wrong with the speedometer of the instrument assembly of the vehicle, which causes the pointer of this meter not to turn.

2. It may be that the wheel speed sensor of the vehicle is out of order, resulting in the watch not working.

It may be that the mileage sensor of the vehicle is out of order, resulting in the watch not working.

Need to check specifically.
