2000 Pontiac Grand Am Repair Question
Pontiac Grand Am Sensor Problem
What were the actual code numbers? The code doesn't tell you what to replace, only that the system thinks there is a problem on that circuit. If they found a crank sensor code, if the sensor is three wire, I check ref voltage--ground and signal before suspecting the crank sensor. If the sensor shares ref voltage or ground, Id have to check whatever shares those circuits.
What is the actual problem? How long since a tune-up?
