Reductant Control Module Internal Temperature Sensor Circuit

Where it lives

For P06F0, the circuit described runs through the sensor. The description of P06F0 reports a fault at the sensor.

Check these first

• A failed internal temperature sensor
• A corroded reductant module connector
• An open or short in the sensor circuit
• A faulty reductant control module
• Water intrusion in the module

What to do next

1. Read the reductant module temperature live
2. Check the sensor circuit for opens or shorts
3. Inspect the connector for corrosion or water
4. Verify module power and ground
5. Replace the module if the sensor is internal
6. Clear the code and retest
