P25CEIntake Camshaft Actuator Park Lock Control Circuit Low Bank 2

P25CE indicates that the powertrain control module (PCM) has detected an abnormally low voltage on the control circuit for the bank 2 intake camshaft actuator park lock. This park lock is a mechanical pin that secures the camshaft phaser in its base timing position when the engine is off, preventing rattle and ensuring a reliable restart. The PCM commands the park lock actuator and monitors the circuit; a low voltage reading means the circuit is grounded when it should not be, or the actuator solenoid has failed.
