P25CCIntake Camshaft Actuator Park Lock Control Circuit High Bank 1

P25CC indicates that the powertrain control module has detected an abnormally high voltage on the intake camshaft actuator park lock control circuit for bank 1, which is the side containing cylinder one. The park lock function mechanically holds the camshaft phaser in its base timing position when the engine is off or during certain operating conditions, and a high voltage reading tells the module that the circuit is open, shorted to power, or the actuator solenoid has failed.
