Chevrolet P0AEE
Drive Motor Temperature Sensor Performance Cause These are type B diagnostic codes, which by definition require two consecutive driving events to request a MIL in the instrument cl
Quick answer
P0AEE is identified in verified Chevrolet service communications as a drive motor inverter temperature sensor performance DTC. For certain vehicles, GM documents a software/calibration issue and released an updated calibration for one condition involving this code.

1. What does P0AEE mean?
P0AEE is identified in verified Chevrolet service communications as a drive motor inverter temperature sensor performance DTC. For certain vehicles, GM documents a software/calibration issue and released an updated calibration for one condition involving this code.
2. Technical explanation
Verified evidence describes P0AEE as “Drive Motor Inverter Temperature Sensor Performance” in Chevrolet/GM manufacturer communications. GM communication PIC6303/PIC6303A classifies P0AEE among Type B diagnostic codes: two consecutive driving events are required before the MIL is requested. The communication also states these diagnostics do not have remedial action that would be noticed by a customer. A separate GM communication, 18NA064, identifies a software anomaly as a possible cause for a listed condition and states that an updated software calibration was released.
3. What system is affected?
Drive motor power inverter module / Hybrid Powertrain Control Module diagnostic monitoring, as described in the verified communications.
4. How serious is this code?
Not yet established by verified evidence.
5. Symptoms you may notice
- The MIL may illuminate after two consecutive driving events for this Type B diagnostic, according to PIC6303/PIC6303A.
- For the condition addressed by 18NA064, customers may see a MIL and/or a “propulsion power reduced” message in the driver information center.
6. Possible causes
- A known calibration weakness is documented for the listed diagnostics in PIC6303.
- A software anomaly is documented as the cause of the condition addressed in 18NA064.
- Other causes are not yet established by verified evidence.
7. Can I still drive the vehicle?
Not yet established by verified evidence.
8. Can I charge the vehicle?
Not yet established by verified evidence.
9. What you can safely do
- Record any instrument-cluster messages and whether reduced propulsion power is displayed.
- Arrange diagnosis by a Chevrolet/GM-qualified service facility.
- Do not attempt high-voltage component diagnosis or repair yourself.
10. Step-by-step troubleshooting
- A technician should verify the customer complaint or concern, as stated in PIC6303/PIC6303A.
- Technicians may find P0AEE stored in the Hybrid Powertrain Control Module, according to PIC6303/PIC6303A.
- For the 18NA064 condition, technicians may find P0AEE in the driver motor power inverter module.
- Check whether the vehicle and condition are covered by the applicable GM calibration guidance.
11. When to contact service
Contact a Chevrolet/GM service facility for diagnosis and to determine whether the applicable calibration update applies to the vehicle.
12. What the service center may check
- Retrieve diagnostic trouble codes from the applicable control module.
- Verify the customer concern and relevant vehicle configuration.
- Determine whether the condition matches GM communication 18NA064 or PIC6303/PIC6303A.
- Check for and, where applicable, install the updated software calibration referenced by 18NA064.
13. Possible repair or resolution
- For the condition covered by 18NA064, GM states that an updated software calibration was released to address the software anomaly.
- No other repair resolution is established by the supplied verified evidence.
