Deutz-Fahr P2200-13: NOx Sensor (Upstream SCR) - Open Circuit

The fault code indicates an open circuit in the NOx sensor located upstream of the SCR (Selective Catalytic Reduction) system. This condition prevents proper communication or operation of the sensor, which may affect emissions control and engine performance.

1. 1

   The wiring and connections to the NOx sensor (upstream SCR)

2. 2

   The integrity of the sensor itself

3. 3

   The circuit for the NOx sensor (upstream SCR)

1. 1

   Inspect
