Sometimes people ignore the existence of the device and just concentrate on the speedometer.

As we already mentioned, claiming the wrong odometer reading is considered a violation of the law, so you should make sure that you do not have an odometer broken. The reasons for that can be various and it depends on what type of odometer you have: Analog or electronic. When you have an older type, there is a chance that cables and gears are already worn down. The mechanical odometer depends on them. When tires move, the input shaft prompts the cable to spin and connect to the output shaft which allows the odometer to work depending on the tire size it is calibrated.  

As for modern odometers, we ask the same: does odometer break for different reasons? Maybe, the sensor breaks down or something is wrong with the electrical components or engine control unit. Sensors track the wheel rotation, then the sensor sends the information to the ECU. Hence, the information is displayed on the dashboard. so, it’s harder to identify the genuine reason for a broken odometer without proper investigation. It is sometimes the sensor’s fault, maybe something is wrong with ECU or the electrical system fails. You will have additional signs in case of a faulty ECU. Basically, they are the followings: 

  • The engine performs poorly. 
  • Check engine light comes on. 
  • The car won’t start.

Generally, mechanical odometers stop working because the gear that spin is made out of plastic and it breaks easily or loses its teeth. All you need to do is replace them. If you are confident in your automotive skills, just remove the dashboard with screwdrivers and change the damaged gear with a new one.
