P003F
A Camshaft Profile Actuator A Control Stuck On Bank 2
Variable valve timing (VVT)
Generic OBD-II
High
What it means
P003F means the "A" camshaft profile actuator on bank 2 is stuck in its "on" (engaged) state — the variable valve-lift mechanism won't switch back, even though the ECM commanded it off. This is usually caused by a sticking solenoid or dirty oil jamming the actuator. Expect reduced power or rough running in part of the rev range; it does not cause a no-start.
High
Can I keep driving? Usually yes — the valve-lift system is stuck in one mode, so expect reduced power or rough running in part of the rpm range; repair to restore normal performance.
Common symptoms
What you'll notice
- Check-engine light on
- Reduced power or poor response in a certain rpm range
- Rough running or uneven idle
- Slightly worse fuel economy
Common causes
Most likely first
- Sticking camshaft profile control solenoid or actuator (bank 2)Likely
- Oil contamination or sludge jamming the actuator (low/dirty oil)Common
- Clogged oil passage or solenoid screenCommon
- Wiring or connector fault holding the actuator energizedLess often
- Failed ECM (rare)Less often
How to diagnose & fix
Work through it in order
- Check oil level and condition — dirty oil is a common cause of stuck cam actuators.
- Remove and clean or replace the cam profile control solenoid and its screen.
- Inspect the actuator wiring and connector.
- Verify the actuator moves freely and holds the correct resistance.
- Clear the code and retest under load.
FAQ
Quick answers
Is it safe to drive with P003F?+
Generally yes for short trips. The valve-lift mechanism is stuck in one mode, so you'll feel weaker performance but the car stays drivable. Fix it to restore normal power.
Can I just clear P003F?+
It will return while the actuator stays stuck. Since dirty oil is a common cause, check the oil and clean the solenoid before clearing.
