What it means
The control module detects that the Bank 2 B camshaft profile control is not performing as expected or is stuck off.
At a glance
- Usually lights the check-engine light
- Affects emissions; the car can fail an emissions test
How it works
Bank 2 B camshaft profile control relies on a locking pin to engage or release the selected camshaft profile. The control module monitors whether the commanded state is reached; P005D sets when Bank 2 B profile control appears stuck off, which can occur if its locking pin remains engaged.
Common causes
Most likely first.
- Locking pin stuck engaged
- Carbon or debris buildup preventing free movement
- Component wear with age - mechanical play
Symptoms
- Check engine light on
- Power loss especially in mid-rpm range
- Possible rough idle or stalling
- Increased fuel consumption
How to diagnose it
- Capture freeze-frame data and check for related Bank 2 cam timing, oil-pressure, or profile-control codes.
- Check oil level and condition and confirm the oil meets the manufacturer's requirements for the engine's profile-control system.
- Inspect Bank 2 B profile-control wiring, connectors, and the oil control valve for loose connections, contamination, or damage.
- Use the manufacturer's scan-tool procedure, where available, to command a Bank 2 B profile change and observe whether the locking state and feedback change.
- If oil supply and electrical control are satisfactory, inspect the Bank 2 B locking pin and mechanism for sticking or wear using the manufacturer's procedure.
Common fixes
- Correct low oil level or service oil that does not meet the manufacturer's requirements.
- Repair a loose connection or damaged Bank 2 B profile-control wiring.
- Clean or replace a sticking Bank 2 B oil control valve if tests identify it as the cause.
- Repair or replace a confirmed stuck or worn Bank 2 B locking pin or profile mechanism.
Can I keep driving?
Avoid hard acceleration if power is reduced, and stop if the engine stalls or becomes severely rough. Continued driving with the Bank 2 B locking pin stuck can worsen drivability and fuel consumption.
