What P0AEE means
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.
P0AEE at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor0.5 to 6 hours
- Clears after repairAfter a drive cycle
Symptoms of P0AEE
- Malfunction indicator lamp, often without drivability change
- Drive system fault warning (Audi)
- Vehicle may not start in hybrid mode
Common causes of P0AEE
- 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)
- Less likelyUneven inverter cooling after soak
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0AEE means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| A | Area: hybrid propulsion. |
| EE | The exact fault in that area. |
What to do next
- Note P0AEE and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0AEE
What does P0AEE mean?
P0AEE means "Drive Motor Inverter Temperature Sensor A Circuit Range/Performance". P0AEE checks whether inverter temperature sensor A reads sensibly. It is a generic code, so it means the same on every make.
Is it safe to drive with P0AEE?
Drive gently and only to a workshop. With P0AEE the car can go into limp mode (reduced power) to protect itself.
Will P0AEE fail an emissions test?
Yes, it can. P0AEE is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0AEE to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 6 hours of work. This is a job for a workshop.
Will P0AEE clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
