The P0B0B fault code refers to a problem with the Auxiliary Transmission Fluid Pump Motor in your vehicle.

The Engine Control Module (ECM) is responsible for monitoring this motor.

When the ECM detects that the signal from the Auxiliary Transmission Fluid Pump Motor is not within the factory specifications, it sets the P0B0B code.

This code specifically indicates that there is a high voltage issue in the supply circuit of the Auxiliary Transmission Fluid Pump Motor. In simpler terms, this fault code means that there is an electrical problem with the motor that helps pump transmission fluid in your vehicle.

The voltage in the supply circuit is too high, which can lead to issues with the motor’s performance. It is important to address this issue promptly to ensure proper functioning of the transmission system in your vehicle.
