| Circuit | Description |
|---|---|
| Signal | The control module input circuit has an internal resistance connected to 5 V. |
| Low Reference | Grounded through the control module. |
| Component | Description |
|---|---|
| B214 Reductant Temperature Sensor | The sensor is a negative temperature coefficient thermistor. As the temperature of the air, fluid, or metal increases, the resistance of the sensor decreases, varying the voltage on the signal circuit. |
| K115 Reductant Control Module | The control module controls the heating and dosing of the reductant. |
