Deutz-Fahr P2031-13: Exhaust Gas Temperature Sensor (Upstream SCR) - Open Circuit

The fault code indicates an open circuit in the exhaust gas temperature sensor located upstream of the selective catalytic reduction (SCR) system. This condition prevents the system from properly monitoring exhaust gas temperature, which can affect emissions control and engine performance.

1. 1

   Wiring and connections to the exhaust gas temperature sensor (upstream SCR)

2. 2

   The integrity of the sensor itself

3. 3

   The circuit for the exhaust gas temperature sensor (upstream SCR)

1. 1

   Inspect

   Inspect the wiring and connections to the exhaust gas temperature sensor (upstream SCR) for damage, corrosion, or loose connections.

2. 2

   Test

   Test the circuit for the exhaust gas temperature sensor (upstream SCR) using a multimeter to confirm the presence of an open circuit.

3. 3

   Replace

   If the sensor or its circuit is found to be faulty, replace the exhaust gas temperature sensor (upstream SCR) with a compatible part.
