P0A01 LEXUS Description

The power management control Electronic Control Unit (ECU) detects HV coolant temperature using the coolant temperature sensor built into the inverter with converter assembly. The power management control ECU uses signals from the coolant temperature sensor to check the effectiveness of the inverter cooling system. 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.
