The P0BD4 fault code refers to a problem with the Drive Motor Inverter Temperature Sensor ‘C’ Circuit. This sensor is located in the inverter of the HV control ECU and is responsible for detecting the temperature of the motor inverter. The motor inverter temperature sensor shares the same characteristics as the boost converter temperature sensor.

It is connected to a cooling system that is independent from the engine cooling system and is used to cool both the MG1 and MG2. The HV control ECU uses the signals from the motor inverter temperature sensor to limit the load and prevent the inverter from overheating. It also detects any malfunctions in the wiring or the sensor itself.

If you receive the P0BD4 fault code, it means that there is a high circuit reading from the Drive Motor Inverter Temperature Sensor ‘C’. This indicates a potential issue with the sensor or its wiring.

It is important to address this problem to ensure the proper functioning of the inverter cooling system and prevent any further damage.

What are the possible causes for the automobile fault code p0bd4?

If you see the engine light or service engine soon warning light on, the fault code P0BD4 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 corrosion. Also, look out for broken, bent, pushed out, or corroded pins in the connectors.
