P001E

A Camshaft Profile Actuator A Control Circuit Low Bank 2

Q: 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.

Q: Can I just clear P001E?

It returns until the low-voltage circuit fault or the actuator is repaired.

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.
