Code P0AE8 Nissan Description
The characteristic of the motor inverter temperature sensor is the same as the boost converter temperature sensor.
The HV control ECU limits the load based on the signals transmitted by the motor inverter temperature sensor, in order to check the effectiveness of the inverter cooling system and prevent the inverter from overheating. Furthermore, the HV control ECU detects a malfunction in the wiring of the motor inverter temperature sensor, as well as in the sensor itself.

- Faulty Inverter With Converter Assembly
- Inverter With Converter Assembly harness is open or shorted
- Inverter With Converter Assembly circuit poor electrical connection
- Faulty HV Control ECU
