DTC SUMMARY
MALFUNCTION DESCRIPTION
These DTCs indicate that the motor inverter temperature sensor value is abnormal. The cause of this malfunction may be one of the following:
Internal inverter malfunctionDESCRIPTION
The motor generator control ECU (MG ECU), which is built into the inverter with converter assembly, detects the temperature of the motor inverter using the motor inverter temperature sensor. If necessary, the motor generator control ECU (MG ECU) will limit inverter output to help prevent the motor inverter from overheating. The motor generator control ECU also detects malfunctions in the sensor based on the temperature sensor values.

Trouble Area | MIL |
Warning Indicate | Note |
---|---|---|---|---|---|---|
P0AED1C | Drive Motor Inverter Temperature Sensor "A" Circuit Voltage Out of Range |
The actual motor inverter temperature high and the difference between the estimated motor inverter temperature and the actual temperature exceeds a threshold for 10 seconds, or after a long soak, the motor inverter temperature sensor value differs from the values of other sensors.
