1991 Oldsmobile 88 3800CC MIL Lamp on
Posted to GM Driveability on 10/6/1998

Mil light remains on as soon as the car is started. Hard code 41 cam sensor diagnostics were done. We checked for a cam signal at the sensor and the ICM (ignition control module) by back probing return wire but could not get a signature reading either way....
