Exhaust Camshaft Position Actuator Park Position Bank 1
2007-2007 Cadillac CTS 3.2L V6
The 2007 Cadillac CTS is equipped with a 3.2L V6 engine. Below you'll find detailed p1012 diagnostic code information including labor time estimates, cost ranges, and technician notes specific to this engine configuration.
Description
The ECM detected that the exhaust camshaft position actuator for Bank 1 is not in the expected park (locked) position at startup. This can cause rough running and increased emissions until the actuator reaches normal operation.
Symptoms
- Check Engine Light
- Rough idle on startup
- Engine rattle noise
- Reduced power
Common Causes
- Low engine oil or low oil pressure
- Faulty exhaust CMP actuator solenoid
- Debris in camshaft actuator system
- Worn crankshaft thrust bearing
- Missing actuator solenoid screen
Diagnostic Steps
- Check engine oil level and condition
- Test oil pressure
- Inspect exhaust CMP actuator solenoid
- Check for debris in actuator system
- Inspect timing chain
Repair Notes
Check oil first. Replace exhaust CMP actuator solenoid if faulty. Ensure solenoid screen is in place.
