HYBRID / BATTERY CONTROL: HYBRID CONTROL SYSTEM: P0AF4-673,P0AF5-674: Open or Short to GND in Rear Motor Inverter Temperature Sensor
P0AF5-674 - Short to B+ in Rear Motor Inverter Temperature Sensor

DESCRIPTION

- The MG ECU located in the inverter with converter assembly detects the temperature of the motor inverter using a temperature sensor built into the inverter with converter assembly. The inverter cooling system operates independently of the engine cooling system. The MG ECU uses signals from the motor inverter temperature sensor to check the effectiveness of the inverter cooling system. If necessary, the MG ECU will limit inverter output to help prevent inverter overheating. The MG ECU also detects malfunctions in the motor inverter temperature sensor and its wiring.
