P001E
A Camshaft Profile Actuator A Control Circuit Low Bank 2
Variable valve timing / lift
Generic OBD-II
High
What it means
P001E means the ECM saw a low-voltage (short-to-ground or open) condition in the control circuit for camshaft profile actuator "A" on bank 2. This actuator switches the variable valve-lift profile; a circuit fault leaves it stuck in one mode, causing rough running and reduced power. The fault is electrical — wiring, connector, or the actuator solenoid — not a timing-chain problem.
High
Can I keep driving? Usually yes, with reduced performance — a valve-lift actuator circuit fault can cause rough running and lost power but doesn't normally stop the car.
Common symptoms
What you'll notice
- Check-engine light on
- Reduced power or sluggish acceleration
- Rough or unstable idle
- Slightly reduced fuel economy
Common causes
Most likely first
- Short-to-ground or open (low-voltage fault) in the actuator control circuitLikely
- Corroded or loose connector at the bank 2 profile actuator / oil control valveCommon
- Failed camshaft profile control solenoid or actuator on bank 2Common
- Poor ground or high-resistance connectionLess often
- ECM control-circuit driver faultLess often
How to diagnose & fix
Work through it in order
- Scan the code and read freeze-frame data to confirm the conditions.
- Inspect the bank 2 actuator connector and wiring for shorts-to-ground or opens.
- Measure the solenoid/actuator resistance against the OEM spec.
- Verify clean power and ground at the actuator connector.
- Replace the actuator/solenoid if out of spec; suspect the ECM only after wiring is verified good.
FAQ
Quick answers
Is it safe to drive with P001E?+
Short-term, usually yes, but with reduced performance and rough running. Extended driving isn't ideal, so get it fixed before it worsens.
Can I just clear P001E?+
It returns until the low-voltage circuit fault or the actuator is repaired.
