Tire size may be off.
Previous owner might have turned it back to improve the value of the car.
It might be broken.
IT might have been broken eariler and replaced with a unit from another car of another mileage.
Yes, the odometer could have stopped and been repaired years later, there's the possibility of manual rollback or the mileage could have just been recorded wrong.
Usually the cluster has failed. You will need a new one, or a used one that has the same mileage showing.
Broken tooth in speedometer head. Replace speedometer head
If your Carfax report shows a rollback on the odometer due to a mistake by the state inspector, try contacting where you had it inspected. If that is not feasible, contact the State and then Carfax.
My speedometer works and the odometer does not because there is a plastic gear in the odometer that is broken.
The year, make, model and what's wrong with it info would help.
Yes, the faulty power steering pressure switch does affect the gas mileage. It will give a wrong reading of the gas mileage. It is therefore important to fix it when it is faulty.
Hey Tony==Either manual or electric spedo if this happens the problem in in the speedo and needs to go to the speedo shop. GoodluckJoe
wrong size tires.
There may be a broken gear inside the odometer.
If the speedo works and not the odometer, take it to the speedo shop as something is wrong in the speedo itself. You can't stop the odometer without stopping the speedo.
To give an accrurate answer....what's wrong with it?
