Drive Motor Inverter Temperature Sensor Circuit Malfunction
The P0AED code indicates a problem in the circuit of the drive motor inverter temperature sensor. This sensor monitors the temperature of the inverter, which converts DC battery power to AC for the electric drive motor. A faulty circuit can lead to inaccurate temperature readings, potentially causing the inverter to overheat or the vehicle to limit power to protect components.
01. Most Common Causes
- Faulty drive motor inverter temperature sensor
- Open or shorted wiring in the sensor circuit
- Poor electrical connection at the sensor or inverter
- Damaged inverter control module
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Reduced motor power or performance
- Overheating warnings or limp mode activation
- Inverter cooling fan running constantly
03. Step-by-Step Diagnosis
Step 1: Use a scan tool to read the code and verify P0AED is present.
Step 2: Inspect the sensor and wiring for visible damage, corrosion, or loose connections.
Step 3: Measure sensor resistance and compare to manufacturer specifications.
Step 4: Check for continuity and shorts in the wiring between sensor and inverter module.
