DTC codes / P27xx · Transmission / P276E
P276E indicates that the transmission control module (TCM) has detected abnormally low current draw from the electric auxiliary transmission fluid pump motor, which is often labeled pump B. The TCM monitors the pump motor circuit and expects a specific current signature when the pump is commanded on; a reading below the calibrated threshold triggers this code.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
