The P0B08 fault code refers to the Auxiliary Transmission Fluid Pump Motor Phase W Current being too high. This code is set by the Engine Control Module (ECM) when it detects that the signal from the motor is outside of the factory specifications.

The Auxiliary Transmission Fluid Pump Motor is responsible for maintaining the proper fluid pressure in the transmission system. When the current in Phase W of the motor is too high, it indicates a potential issue with the motor or its electrical circuit. If you encounter this fault code, it is important to have the motor and its electrical connections inspected and tested.

A high current in Phase W could lead to excessive wear on the motor or even motor failure, which can result in transmission problems. Addressing this issue promptly can help prevent further damage and ensure the smooth operation of your vehicle’s transmission system.
