   The temperature sensor located upstream of the SCR catalyst

2. 2

   The wiring and connections to the temperature sensor

3. 3

   The control unit's interpretation of the sensor signal

1. 1

   Inspect

   Inspect the temperature sensor located upstream of the SCR catalyst for physical damage or contamination.

2. 2

   Test

   Test the wiring and connections to the temperature sensor for continuity and proper voltage.

3. 3

   Verify

   Verify the control unit's interpretation of the sensor signal using diagnostic tools.
