The factors influencing the cost of diagnosing and fixing the automobile fault code p0b0b based on the estimated repair time of 1.0 hour include the hourly rate charged by auto repair shops, which typically ranges between $75 and $150.

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.

What are the possible causes for the automobile fault code p0b0b?

If you see the engine light or service engine soon warning light on, the fault code P0B0B could be the culprit. This code is often caused by a faulty auxiliary transmission fluid pump, an open or shorted harness, or a poor electrical connection in the pump circuit. To fix the issue, visually inspect the wiring harness and connectors, checking for any damage or corrosion. Also, be sure to look out for broken, bent, pushed out, or corroded pins in the connectors.

How can I visually inspect the wiring harness and connectors to fix the fault code p0b0b?

If you’re dealing with the fault code p0b0b and your engine light is on, it’s time to visually inspect the wiring harness and connectors. This could be caused by a faulty auxiliary transmission fluid pump, an open or shorted pump harness, or a poor electrical connection in the pump circuit. To fix it, check the possible causes mentioned earlier and give the wiring harness and connectors a thorough visual inspection.
