P001D A Camshaft Profile Actuator A Control Circuit/Open Bank 2
Open circuit at the cam profile actuator (intake, profile A, bank 2). Same fault as P001A but 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 P001D?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
