The vehicle speed sensor and speedometer are one in the same on this model I believe. If one goes out it takes the other with it if its all electronic and not cable driven.

What are the symptoms of a speed sensor going bad on a 1997 jeep grand cherokee laredo 6 cyl.


Since alot of things rely on data from the speed sensor you will "usually" get an ABS alarm, little or no shifting,no indication of speed on the speedometer, and the check engine light. without the abs light and with a speed indicated I would lean toward a transmission problem

I have a 1998 Jeep Grand Cherokee Limited 5.2 v8. Engine was lugging check engine light came on as engine quit. Pulled over turned off the key and it restarted and ran fine. Went to Auto ZOne they said...


Hello there, One of the problems Jeeps do have is Transmissions. It is very typical of the sensors and solonoid packs to go bad, Also Jeeps as well have well know problems with the computer causing transmission issues as well.

I suggest taking it to a shop other than a parts store they are great for basic info but a repair shop can actually look at what each sensor is doing in real time.

You are on the right track and I would most definetly address this asap rather than causing internal transmission problems.

Good luck and I hope this helps.
