P0AEE: Drive Motor Inverter Temperature Sensor A Circuit Range/Performance

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.

Symptoms

• Malfunction indicator lamp, often without drivability change
• Drive system fault warning (Audi)
• Vehicle may not start in hybrid mode

Most likely causes

• Controller software error (Audi Q5/A7 e quattro bulletin)
• Inverter temperature sensor A drifting out of tolerance
• Failing power inverter module (e.g. Honda MPI solder joints)
• Uneven inverter cooling after soak

What to check, in order

Start with the simplest. You can tick off each step.

1. Read the codes with a hybrid-compatible scanner and write down the freeze frame data
2. Compare the reading with other engine data while varying the engine speed.
3. Make sure the battery cooling air intake is clean
4. Check the 12 V auxiliary battery, which can also trigger warnings
5. Leave any high-voltage measurements to a specialized repair shop

Good to know

• It can trigger limp mode.
• It affects emissions.

What each character of P0AEE means

• P: Powertrain: engine and transmission
• 0: Generic code: same on every make
• A: Hybrid or air and fuel
• EE: Specific fault in that system

Frequently asked questions

Can I keep driving with code P0AEE?

If the car still runs, drive as little as possible and go to a specialized repair shop. Do not touch the orange cables: they carry high voltage.

What causes code P0AEE?

The most common causes are: controller software error (Audi Q5/A7 e quattro bulletin); inverter temperature sensor A drifting out of tolerance; failing power inverter module (e.g. Honda MPI solder joints).
