Jeep Liberty - speed senser replaced - doesn't work

https://www.700r4transmissionhq.com/jeep-liberty-speedometer-not-working/

If the speedometer does not work but the odometer does, the problem is in the speedo cluster. If neither work, it may be the speed sensor on the side of the transmission.

The routing of the speed sensor wires is located on the rear differential. The problem is that they rub on the E-brake cable and once the wire is exposed they short and the speedometer and any other options running off the speed sensor quit working and that includes the transmission shift points and can cause the torque converter to not unlock and cause stalls. We went to a dealer and got the replacement kit for $32.00. He also took the time to encase the wires in a plastic tubing to avoid this problem again.

Hi

Check if there fuses related to the speed sensor or speedometer. there could an expose cable that might have triggered the speedometer to work.

Sure you can if a mechanic can do it so can you if you have the right tools and knowlege. First you need to know which one thers's one at each whell at the fround rear end housingf the rear rear end housing and the one in the side of the transfer case where the speedometer cable would'of connected on an older model and then theors three in the sides of the trans mission, Touque converter speed forward turbine speed output turbine speed. What proble are you trying to fix? the speedometer not working? Abs light on? Cheack engine light on? Cruise control not working? If the cruise control does work the speed senser is good and the check engine light will be on if the speed senser is'nt working. If the speed senser is'nt working the car will only take off in low and not shift to seecond or any higher gear as the computer doesn't know how fast the car is going. If the speedometer is'nt working and it does shift and cruise and the check engine light is'nt on then the speed senser is working but the speedometer is'nt if it is'nt and everything else is woring then as your driving hit the speedometer with your fist and see if it comes back on they can get stuck and i've fixed quite a few and they stayed fixed. On to wheel drive models with the rear wheels jacked off the ground safty I've run the car up to speed and trying wiggleing the wires and connectors till I wiggled the right thing till the speedometer came on ( including smacking the speedometer ) Just don't hit it too hard as it'll bust just like anything else.

need to go to nearest dealer to update tps and wcm

Are you looking for a certain sensor? What engine?

Your vehicle is equipped with a tire pressure montioring system. The message is stating one of the sensers has a fault. This will require attention by either a reputable tire shop or chysler dealer. Senser replacement may be requried (about 150 installed). The senser is located inside the tire/wheel assembly. Hope this helps. Please leave feed back.

It is located on the rear diff. at the top. The cable for the parking brake crosses close by and messes up the wiring.

I have a 2002 Jeep Liberty Limited with the same problem. The main problem I have found to be the routing of the speed sensor wires located on the rear difrential. They are 2 blue wires on my jeep and probably the same on yours. The problem is that they rub on the E-brake cable and once the wire is exposed they short and the speedometer and any other options running off they speed sensor quit working and that includes the tranny shift points and can cause the torque converter to not unlock and cause stalls. I am having the same problem for the third time and chrysler and jeep are both aware of the problem and unwilling to repair the problem or post a recall.
