DTC codes / P25xx · Vehicle speed, idle control and auxiliary inputs / P25CE
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.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
