How to fix P0BCF code

Check the “possible causes” listed above. Visually inspect the cable harness and associated connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.

P0BCF Possible Symptoms

Check engine light on (or service engine soon warning light)

P0BCF Meaning

The MG ECU located in the inverter with converter assembly detects the generator inverter temperature using the temperature sensor integrated into the generator inverter. If necessary, the MG ECU will limit the inverter output to prevent overheating of the generator inverter. The Power Management Control ECU (HV CPU) also detects sensor malfunctions based on temperature sensor values. The inverter with converter converts malfunctions of the generator inverter temperature sensor and its wiring.
