Diagnostic Aids

WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

Check for any of the following conditions:

The Crankshaft Position Sensor B parameter on the scan tool is normally zero counts. Only when the PCM has determined the CKP sensor A signal to be missing or unreliable, does the scan tool display a rolling count on for CKP sensor B.
If DTC P0335 and DTC P0385 are both setting, inspect for a loose CKP sensor assembly or damage, foreign material on the crankshaft signal rotor.

An intermittent malfunction may be caused by a fault in the CKP sensor electrical circuit. Inspect the wiring harness and the components for an intermittent condition. Refer to Intermittent Conditions .

Repair any electrical circuit faults that were found. Refer to Wiring Repairs .

The information included in the Freeze Frame data can be useful in determining the vehicle operating conditions when the DTC first set.
