Reductant Tank Temperature Sensor Circuit Low

The Reductant Tank Temperature sensor is mounted internal to the Reductant Tank Level Sensor. It is used to control the activation of the Reductant Tank Heater as well as an enabler to the Level Sensor (which cannot read level when the reductant is frozen).

Cause:
Faulty Reductant Tank Temperature Sensor
Reductant Tank Temperature Sensor harness is open or shorted
Reductant Tank Temperature Sensor circuit poor electrical connection

Symptoms:
Check engine light
