P0AEEDrive Motor Inverter Temperature Sensor A Circuit Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- P0AEE checks whether inverter temperature sensor A reads sensibly. GM's 2016 to 2019 tables compare it after a cold soak with an average temperature of the vehicle; more than 20 °C apart sets Type B, two trips. The 2011 Volt compares it with the other power electronics sensors (20 °C, Type A), the 2013 two-mode trucks after 360 minutes off (15 °C), eAssist with module and MGU temperatures (20 °C). GM bulletin PIC6303A notes that on Volt, Malibu and LaCrosse with 5ET50 the code alone triggers no remedy; the inverter is only replaced with P0AC4. Audi fixes P0AEE00 on Q5 and A7 e quattro by software, and Honda lists it among inverter faults of the 2012-15 Civic Hybrid with extended warranty.
- What you may notice
- Malfunction indicator lamp, often without drivability change
- Drive system fault warning (Audi)
- Vehicle may not start in hybrid mode
- Likely causes
- PossibleController software error (Audi Q5/A7 e quattro bulletin)
- PossibleInverter temperature sensor A drifting out of tolerance
- PossibleFailing power inverter module (e.g. Honda MPI solder joints)
- RareUneven inverter cooling after soak
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
