PONTIAC GRAND AM SENSOR PROBLEM

2000 Pontiac Grand Am • 147,000 miles

Had crank position senor replaced cause it was bad hoping it would help car start better. Had starter and battery tested and everything was good alternator was good to. Autozone put it on computer and bad crank sensor was bad. Still acting up. Do you have any idea what it could be?

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?
