Why Odometers Are Needed & How You Can Get Yours Reset For Less?

The odometer in your car is the gizmo on your car dashboard that tracks how many miles your car has travelled during its life, which plays an important part in determining your car’s value.

Like any car part, your odometer can malfunction and when it does, any miles that you subsequently drive aren’t going to register, so getting it fixed really is quite important.

In this article, we look into what odometer correction, why it’s necessary to get it fixed and how you can do it for yourself and avoid costly garage fees. So, let’s start at the beginning with a quick description of why odometers sometimes go wrong.

Why Do Odometers Malfunction?

When your odometer malfunctions, it can be for a number of reasons.

  • Firstly, it could be a broken gear inside the speedometer system itself or it could be a poorly functioning speed sensor.
  • It could even be a faulty ECU or Engine Control Unit that’s to blame, but however it’s being caused, you’ll need to sort it out, as the mileage being shown by your odometer is false.

Odometer correction is necessary because otherwise you’ll get a lot less for your car when you come to sell it. And that’s because you have to declare to any individual or dealer that it’s not working under the strict rules that are in place to odometer rollback fraud.
