Hi all, Can't seem to find the answer searching, so thought someone might be able to help On my 1990 Celsior, on start-up my check engine light and traction control lights come on and stay on. This does not occur if I immediately put the car in drive and go. Diagnostics indicate "RPM sensor #2" Can anyone point me in the right direction? Where are the RPM sensors located? Any help or experience with this would be appreciated.

I wasn't aware there was a RPM sensor let alone 2 of them ? There are 2 igniters , 2 cam position sensors , 2 ignition coils and an engine speed sensor . The ESS is down under the crank pulley slightly on the left side or your right side if you are standing at the front looking at the engine.
