DTC codes / P25xx · Vehicle speed, idle control and auxiliary inputs / P25CF
P25CF means the powertrain control module (PCM) has detected an abnormally high voltage on the control circuit for the bank 2 intake camshaft actuator park lock. The park lock is a mechanical pin that holds the camshaft phaser in its base timing position when the engine is off, and the PCM commands it through a solenoid or motor circuit. A high voltage reading tells the PCM that the circuit is open, shorted to power, or that the actuator's internal coil has failed.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
