The VSS go bad from time to time and are easy to replace. Although I am interested in why Dave is asking about the CEL.

Re: Speedometer doesn't work

just check your connection so the speedo sensor in the back drivers side of the tranny. is your electronic or mechanical? 91 i would think electric. might just be a bad connection.

if the CEL is on(or a code for VSS set), it almost garranties the sensor or wiring between it and the ECM is bad, if there is no code, there is a problem between the ECM and the speedo
