DTC codes / P09xx · Transmission / P0965
P0965 means the transmission control module (TCM) has detected that the electrical current in the control circuit for pressure control solenoid 'B' is outside the expected range or is not responding as commanded. The TCM monitors the solenoid's current draw and compares it to the desired value; when the actual current stays too high, too low, or erratic for a calibrated time, it sets this code and typically illuminates the check engine light.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
