The P0AED: Drive Motor Inverter Temperature Sensor “A” Circuit refers to an issue with the temperature sensor “A” in the drive motor inverter system. This sensor monitors the temperature of the inverter, which controls the electric drive motor in hybrid or electric vehicles. A fault in this circuit can be caused by a malfunctioning temperature sensor, wiring issues, or problems with the control module.

P0AED Meaning
The P0AED: Drive Motor Inverter Temperature Sensor “A” Circuit fault code indicates a problem with the temperature sensor “A” in the drive motor inverter circuit. This sensor is responsible for monitoring the temperature of the drive motor inverter, which manages power flow to the electric motor. If the sensor is malfunctioning, it can lead to incorrect temperature readings, potentially causing the inverter to overheat and reducing the efficiency and performance of the electric drivetrain.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for any related fault codes that might provide more information about the issue. | OBD-II Scanner |
| Test Temperature Sensor “A” Circuit | Use a multimeter or diagnostic tool to test the drive motor inverter temperature sensor “A” circuit for proper operation. Compare the readings with the manufacturer specifications. | Multimeter, Diagnostic Tool |
| Inspect Wiring for Damage | Visually inspect the wiring associated with temperature sensor “A” for signs of damage, disconnections, or corrosion that may be causing the fault. | Flashlight, Multimeter |
| Test Control Module Functionality | Use a diagnostic tool to test the control module to ensure it is properly managing the signals from the temperature sensor “A”. | Diagnostic Tool, Multimeter |
| Repair or Replace Components | If necessary, repair or replace the temperature sensor, faulty wiring, or control module to resolve the issue. | Repair Tools, Replacement Parts |
| Clear the Code and Test Drive | After completing repairs, clear the code using an OBD-II scanner and take the vehicle for a test drive to confirm that the issue has been resolved. | OBD-II Scanner |
| Recheck for Codes | Re-scan the vehicle after the test drive to ensure the P0AED code does not return. | OBD-II Scanner |
