Code P0BCE Toyota Description

The MG ECU located in the inverter with converter assembly detects the temperature of the generator inverter using the temperature sensor built into the generator inverter. If necessary, the MG ECU will limit inverter output to help prevent generator inverter overheating. The power management control ECU (HV CPU) also detects malfunctions in the sensor based on the temperature sensor values. The inverter with converter assembly detects malfunctions in the generator inverter temperature sensor and its wiring.
