Q: When I drive the mileage on my car does not change

asked by on

I got the car from a buy here pay here place. Since the signed the paperwork 2 days ago, the mileage for the car has stayed the same. The car was listed as 124956, and had not changed since the left the lot. What does this mean when the mileage is not changing on a car

My car has 124956 miles.
My car has an automatic transmission.

Hi There, This could be related to a couple of possibilities. The [instrument voltage regulator]((https://www.yourmechanic.com/services/instrument-voltage-regulator-replacement) regulates the voltage supplied to the various gauges in your vehicle’s dash. When this is not working properly, this may cause the gauges in your dash to dim or flicker erratically or in some cases provide false readings. This may also be caused by a faulty instrument gauge cluster.

This may also be caused by a faulty transmission speed sensor. The speed sensor reads the rotational speed of the reluctor wheel, located within the transmission. The speed sensor also controls the anti-lock braking system. Driving with a bad speed sensor usually causes the ABS to malfunction and can lead to loss of braking power and/or an accident. When this is not working properly, you may also notice the transmission hesitating to shift gears, erratic tachometer readings, the speedometer not working properly or the odometer not working properly. I would recommend having an expert from YourMechanic come to your location to diagnose and inspect your vehicle.
