DTC codes / P27xx · Transmission / P27BD
P27BD indicates that the transmission control module (TCM) has detected an open circuit or electrical fault in the control circuit for pressure control solenoid N, which is used to regulate hydraulic pressure inside the transmission. The computer monitors the solenoid's electrical path and sets this code when expected current flow is absent or out of range, meaning the solenoid cannot be commanded properly.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
