P0B0D Meaning
The electronic transmission fluid auxiliary pump is used to keep the transmission engaged when the engine is stopped and the transmission is running. The transmission control module (TCM) monitors the electronic transmission fluid auxiliary pump control circuit. The TCM sets the OBDII code when the signal from the electronic transmission fluid auxiliary pump control circuit is outside factory specifications.
