My speedometer will sometimes quit and the fault will light the check engine light as well as the trany fault light. I can clear it and it will return after a while. The speedometer usually restarts after driving a short time. Appears to be a random fault that sets stops the speedometer when in failed mode then corrects itself restarting the speedometer. I replaced the rear speed sensor in the differential with a good used one, but it did not improve the problem. Any ideas?

I replaced mine and it fixed the problem. I orderd a module from http://www.midwest-abs.com. instead of a $800 fix at the dealer, they sent me one for $89. Comes with instructions and all you need. The ABS module controls more than the brakes. Reply Leave a Reply Cancel reply Your email address will not be published.
