WysokiAuxiliary Transmission Fluid (ATF) Pump Control Module – Circuit High Voltage/Signal. This code indicates that the engine control module (ECM/PCM) has detected an abnormally high electrical signal in the control module circuit for the auxiliary transmission fluid pump.
Code P0C25 means the vehicle controller has detected too high voltage in the control module circuit for the auxiliary transmission fluid pump. This can lead to incorrect transmission operation, including delayed gear shifts or fail-safe mode. The cause may be damaged wires, a short circuit, or a faulty module – for a precise diagnosis, a visit to a professional workshop is recommended.
Symptoms
Check Engine light illumination; problems with gear shifting (delays, violent jerking); possible transition to transmission fail-safe mode (limp mode); error messages on the dashboard related to the drivetrain system; occasional transmission fluid leak.
Possible causes
Damage to the auxiliary transmission fluid pump control module Open circuit or short circuit in the module wiring harness (short to ground/power, high resistance) Contaminated or low transmission fluid level Faulty connectors, corrosion, or moisture in the module connector Damage to the auxiliary fluid pump itself
