2002 jeep liberty speed sensor problems. I am having problems keeping it working. I have replaced the sensor twice and replaced the wire harness and yet after an hour of continuous driving. It quits for a least 1 or 2 days then starts. Any idea as to the problem

Did you replace the sensor in the rear differential at the top?

It serves as an abs and speedometer sensor.

Yes I did. But that was before I changed the wire harness. Wire harness was changed due to possible broken wires. Is it possible that the sensor is now damaged

Not really. Have a shop check it with a scan tool to verify the signal is reaching the pcm
