Q: What does code P27C2 mean?

Pressure Control Solenoid P Stuck On. P27C2 indicates that the transmission control module (TCM) has detected a fault where pressure control solenoid P is stuck in the energized or 'on' state, meaning it is commanding a pressure change that the solenoid is not actually delivering. The TCM monitors the solenoid's electrical circuit and hydraulic response, and when the expected current or pressure feedback does not match the command, it sets this code and typically illuminates the malfunction indicator lamp (MIL).
