I just bought a 2002 Jeep Liberty and the speedometer, odometer and cruise control just went out and the engine light came on saying the speed sensor is bad. We already changed the speed sensor on the transmission but it didn’t work. So my question is did I change the wrong speed sensor?? I found a post that says I need to change the speed sensor on the rear differential to fix the speedometer, not the transmission sensor. Anyone know the answer to this. The cluster is fine I did the self test on it and it passed.
