Exhaust Camshaft Position Actuator Park Position Bank 2
on 2010 Buick Enclave 3.6L V6 · AWD
What this code means
The ECM detected that the exhaust camshaft position actuator for Bank 2 is not in the expected park (locked) position during engine startup. The variable timing system is very sensitive to oil cleanliness and pressure.
Symptoms
- Check Engine Light
- Rough idle on startup
- Rattling noise from engine top
- Reduced power mode
- Delayed acceleration
Common causes
- Low engine oil level or low oil pressure
- Faulty CMP actuator solenoid
- Missing camshaft actuator solenoid screen
- Dirty or contaminated engine oil
- Debris in camshaft actuator system
- Worn timing chain or guides
Diagnostic steps
- Check engine oil level and quality
- Test oil pressure at startup
- Inspect CMP actuator solenoid and screen for debris
- Monitor camshaft position with scan tool
- Check timing chain condition
Repair notes
Most commonly caused by low oil level/pressure or a faulty solenoid. Check oil first, then inspect solenoid screens. Replace solenoid if needed. Oil temperature, viscosity, and quality directly affect phaser responsiveness.
