DTC P0AED-1C: Drive Motor Inverter Temperature Sensor "A" Circuit Voltage Out of Range [12/2019 - 11/2023]: Description

WARNING: This page is about a different variant/trim than selected.

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.

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Warning Indicate
P0AED-1C 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.
