Drive Motor A Temperature Sensor B Circuit High

Where it lives

For P2DAF, the sensor sits on the circuit this code reports. The description of P2DAF reports a fault at the sensor.

Check these first

• A short to voltage on the sensor B signal wire
• A failed sensor B reading high
• Drive motor A actually overheating
• Corrosion at the sensor B connector
• A faulty inverter temperature input

What to do next

1. Read drive motor A temperature sensor B
2. Inspect the sensor B signal wire for a short to voltage
3. Check the drive motor A coolant flow
4. Test the sensor B resistance
5. Repair the short if the reading stays high
6. Clear the code and retest
