B Camshaft Profile Actuator A Control Stuck On Bank 1

Where it lives

For P005B, the description names the actuator as the part involved. The description of P005B puts it on bank 1.

Check these first

• A B camshaft profile actuator stuck in the advanced position on Bank 1
• Debris or varnish keeping the actuator spool from returning
• A shorted Bank 1 B camshaft profile solenoid holding the actuator on
• A camshaft position reading that makes the ECM see the actuator stuck on
• Low oil pressure letting the actuator fail to release

What to do next

1. Read camshaft position and profile actuator data with a scan tool
2. Test the Bank 1 B camshaft profile solenoid circuit for a short
3. Check engine oil level and pressure
4. Inspect the actuator for debris or varnish
5. Replace the Bank 1 B camshaft profile actuator if it stays advanced
6. Clear the code and retest
