Speedometer Not Working

[JeanO-Mac]

Hi everyone

My mechanic replaced both sensors on my 2003 Jeep Liberty Sport.
He said he examined all wiring and cannot figure out why the speedometer still isn’t working. At random it will bounce up and down and then stop all together: has anyone experienced this and if so, what is the solution to this problem?

Just above the rear differential, is where the speed sensor is located.
The sensor may need replacement. It has a 2 wire connection, with wire loom tubing.
A known issue and inspection for chaffed wiring may be present as well.

Thank you. My mechanic replaced both sensors associated with the speedometer and it still isn’t working

The 2 wires should then be fully inspected. Keep in mind wires are in between the split loom tubing.
Are there any OBD2 codes present?
