Q: What does code P27D3 mean?

Pressure Control Solenoid S Electrical. P27D3 means the transmission control module (TCM) has detected an electrical fault in the circuit for pressure control solenoid S, which is a shift solenoid used to regulate hydraulic pressure inside the automatic transmission. The TCM monitors the solenoid's electrical current and voltage and sets this code when the readings fall outside the expected range, indicating an open circuit, short circuit, or internal solenoid failure.
