P003E
A Camshaft Profile Actuator A Control Performance/Stuck Off Bank 2
Variable valve lift / cam control
Generic OBD-II
High
What it means
P003E means the 'A' camshaft profile (variable valve lift) actuator on bank 2 isn't performing as commanded and appears stuck in the 'off' (default) position. The engine stays in its low-lift cam mode and can't switch to the high-performance profile, so you lose top-end power. The check-engine light comes on; it isn't a no-start fault.
High
Can I keep driving? Driveable but down on power — the engine is stuck in its low-lift cam mode, so it can't reach its high-performance profile. Fix it to restore full power.
Common symptoms
What you'll notice
- Check-engine light on
- Noticeable loss of high-rpm power
- Engine stuck in economy/low-lift mode
- Slightly rough running under load on some engines
Common causes
Most likely first
- Camshaft profile actuator mechanically stuck or seized offLikely
- Low oil pressure or dirty oil preventing engagement (oil-actuated systems)Common
- Failed actuator solenoidCommon
- Wiring or connector fault in the actuator circuitLess often
- Failed ECM driverLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and check engine oil level and condition first — low or dirty oil is a common cause on oil-actuated cam systems.
- Command the actuator with a scan tool and watch for a response.
- Test the actuator solenoid resistance and inspect its wiring and connector.
- Inspect the actuator and its oil passage/screen for sticking or clogging.
- If everything tests good, suspect the ECM driver. Clear and re-test.
FAQ
Quick answers
Is it safe to drive with P003E?+
Yes for normal driving, though you'll notice less top-end power. Because a stuck actuator can be oil-related, don't ignore it — check the oil and repair it soon.
Can I just clear P003E?+
It returns as soon as the actuator fails to respond again. Address the oil, actuator, or wiring rather than only resetting it.
