P0C2BElectric/Auxiliary Transmission Fluid Pump Control Module Feedback Signal

P0C2B is a generic powertrain code that indicates the transmission control module (TCM) has detected an abnormal feedback signal from the electric or auxiliary transmission fluid pump control module. The TCM expects a specific voltage or current pattern on the feedback circuit that confirms the pump is operating as commanded, and when that signal falls outside the expected range, the code is stored and the check engine light is illuminated.
