I have a 1995 Cherokee 2WD AW4, 4.0 Automatic.

The speedometer and odometer died a couple weeks back, threw CEL with code 15 no vehicle speed sensor signal. I have replaced the VSS as well as checked and clean the connectors from the VSS to the connector behind / next to the valve cover gasket and several other connections also have checked all fuses.

Back in December my trip odometer quite working when I tried to reset but would "click" trying to turn, this told me a tooth was broke in the trip od.

Questions I am looking for input on.
1) Would the CPU through the VSS code if it is something behind or in the dash panel such as bad connection or failed electronic?
2) could the Trip OD have caused a failure in the reg OD and Speedo mechanics or electronics?
3) any other connectors or points I should check under the hood before pulling the cluster out?

I will be pulling the dash this weekend but wanted to check for any other input before I do so.

 

check out you NSS that could be causing a problem too. I had the same thing happen on my xj I cleaned the NSS and the problem went away. I dont know if it would be the same from a 95 to a 98 but it is worth a shot.

 

Pull speedo gear housing check the plastic gear condition. Mark the housing so you install it back exactly as it came out.
