The factors influencing the cost of diagnosing and fixing the automobile fault code P0BD1 are the estimated repair time of 1.0 hour and the typical hourly rate charged by auto repair shops, which ranges from $75 to $150.

The P0BD1 fault code refers to a problem with the Drive Motor Inverter Temperature Sensor ‘C’ Circuit. This sensor is located within the inverter and is used by the HV control ECU to monitor the temperature of the motor inverter.

The inverter is cooled by the same system that cools the MG1 and MG2, and this cooling system is separate from the engine cooling system.

The motor inverter temperature sensor is similar to the boost converter temperature sensor. The HV control ECU uses the signals from the motor inverter temperature sensor to limit the load and ensure the effectiveness of the inverter cooling system, preventing overheating. It also detects any issues with the wiring or the sensor itself.

If you encounter the P0BD1 fault code, it indicates a problem with the Drive Motor Inverter Temperature Sensor ‘C’ Circuit.

What are the possible causes for the automobile fault code P0BD1?

If you see the engine light or service engine soon warning light on, the fault code P0BD1 could be the culprit. This code is often caused by a faulty inverter with converter assembly, an open or shorted harness, a poor electrical connection in the inverter with converter assembly circuit, or a faulty HV control ECU. To fix the issue, visually inspect the wiring harness and connectors, checking for any damage or broken, bent, pushed out, or corroded pins. Don’t forget to consider the possible causes mentioned above.

How can I visually inspect the wiring harness and connectors to fix the P0BD1 fault code?
