If necessary, the power management control ECU will limit inverter output to help prevent inverter overheating. The power management control ECU also detects malfunctions in the sensor based on the HV coolant temperature sensor values. The inverter with converter assembly detects malfunctions in the HV coolant temperature sensor and its wiring.
