Deutz-Fahr P3033-96: 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 circuit of the downstream SCR NOx sensor

2. 2

   The connection and integrity of the wiring to the downstream SCR NOx sensor

1. 1

   Inspect

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

2. 2

   Test

   Use a multimeter to test the resistance of the heater in the downstream SCR NOx sensor, comparing it to the manufacturer's specifications.
