Crankshaft Position System Variation Not Learned
2002-2007 Buick Rendezvous 3.4L V6
Description
The CKP system variation values have not been programmed into the PCM. This code commonly appears after replacing the crankshaft position sensor, PCM, or performing certain engine repairs. A CKP variation learn procedure must be performed using a compatible scan tool.
Symptoms
- Check Engine Light
- Engine may run rough
- Possible intermittent stalling
- Misfire codes may accompany
Common Causes
- CKP variation learn procedure not performed after sensor replacement
- PCM replacement without relearn
- Engine repairs that disturbed CKP timing
- Battery disconnect that cleared learned values
Diagnostic Steps
- Connect GM-compatible scan tool
- Perform CKP System Variation Learn procedure
- Warm engine to operating temperature
- Follow scan tool prompts for learn sequence (typically involves specific RPM targets)
- Clear codes after successful learn
Repair Notes
Perform CKP variation learn procedure with a scan tool. This requires bringing the engine to specific RPM ranges and holding steady as directed by the scan tool.
