DTC P0AEF-275: Drive Motor Inverter Temperature Sensor "A" Circuit Low; DTC P0AF0-274: Drive Motor Inverter Temperature Sensor "A" Circuit High: Description
WARNING: This page is about a different variant/trim than selected.
- The MG ECU located in the inverter with converter assembly detects the temperature of the motor inverter using the 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. The MG ECU uses the signal 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 prevent inverter overheating. The MG ECU also detects a malfunction of the front motor inverter temperature sensor or its circuit.
