| DTC Code | DTC Name |
|---|---|
| P0AEF-275 | Drive Motor Inverter Temperature Sensor "A" Circuit Low |
| P0AF0-274 | Drive Motor Inverter Temperature Sensor "A" Circuit High |
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 is the same as that for MG2 and MG1, and it operates independently of the engine cooling system. The characteristics of the motor inverter temperature sensor are the same as those of the boost converter temperature sensor (Click here). 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.
