P001F A Camshaft Profile Actuator A Control Circuit High Bank 2
Excessively high control voltage at the cam profile actuator (intake, profile A, bank 2). Same fault as P001C on bank 2. The cam phaser actuator adjusts intake/exhaust timing under load — a stuck or slow phaser kills mid-rpm torque and can throw correlation codes between cam and crank.
Is it safe to drive with P001F?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
Common causes
- Most likelyWiring shorted to battery voltage
- Less likelyConnector pins corroded - high contact resistance
- Less likelySupply wire pinched against B+ source
Symptoms
- Check engine light on
- Power loss especially in mid-rpm range
- Possible rough idle or stalling
