Troubleshooting Kia Sorento: How to Fix Speedometer Issues?

I recently bought a used Kia Sorento and noticed that the speedometer is not functioning properly. Sometimes it shows the wrong speed or doesn't move at all. What could be causing this issue and how can I fix it?

First, check the speed sensor located on the transmission. It could be dirty or damaged, causing incorrect readings on the speedometer.

Another possible cause is a faulty speedometer cable. This should be replaced by a professional mechanic.

If the issue still persists, it could be a problem with the speedometer itself. You may need to have it replaced or recalibrated.
