Intake Camshaft Position Actuator Park Position Bank 1
on 2010 GMC Terrain 3.6L V6 · FWD
What this code means
The ECM detected that the intake camshaft position actuator for Bank 1 is not in the expected park (locked) position during engine startup. The CMP actuator has a locking pin that prevents movement until sufficient oil pressure is available.
Symptoms
- Check Engine Light
- Rough idle on startup
- Engine rattle on cold start
- Reduced power
- Poor fuel economy
Common causes
- Low engine oil level
- Low oil pressure
- Dirty or contaminated engine oil
- Faulty CMP actuator solenoid
- Missing CMP actuator solenoid screen
- Worn timing chain
Diagnostic steps
- Check engine oil level and condition
- Test oil pressure
- Inspect CMP actuator solenoid and screen
- Monitor camshaft position with scan tool
- Check timing chain tension
Repair notes
Start by checking oil level and quality. Clean or replace CMP actuator solenoid. If solenoid screen is missing, replace solenoid and change oil/filter.
