Intake Camshaft Position Actuator Park Position Bank 1
2019-2019 Buick Enclave 3.6L V6
The 2019 Buick Enclave is equipped with a 3.6L V6 engine. Below you'll find detailed p1011 diagnostic code information including labor time estimates, cost ranges, and technician notes specific to this engine configuration.
Description
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.
