Deutz-Fahr P220F-00: Heater Performance Error in Downstream SCR NOx Sensor

The fault code indicates a performance issue with the heater in the downstream selective catalytic reduction (SCR) NOx sensor. This may affect the sensor's ability to function properly, potentially impacting emissions control.

1. 1

   The heater element of the downstream SCR NOx sensor

2. 2

   The wiring and connections to the downstream SCR NOx sensor

3. 3

   The power supply to the downstream SCR NOx sensor

1. 1

   Inspect

   Inspect the heater element of the downstream SCR NOx sensor for visible damage or wear.

2. 2

   Check

   Check the wiring and connections to the downstream SCR NOx sensor for looseness, corrosion, or damage.

3. 3

   Verify

   Verify the power supply to the downstream SCR NOx sensor is functioning as expected.
