4WD/AWD Power Transfer Unit Temperature Sensor

Where it lives

For C0093, start at the sensor the description names.

Check these first

• The transfer unit temperature sensor fouled by oil or debris
• A failed sensing element inside the sensor
• A temperature signal that drifts and reads wrong
• A wrong sensor fitted to the transfer unit
• A corroded or loose sensor connector

What to do next

1. Read the sensor temperature on a scan tool
2. Inspect the sensor and connector for oil or damage
3. Confirm the correct sensor part number
4. Replace the sensor if the reading is out of range
5. Clear the code and retest after a drive
