Deutz-Fahr 1407: Exhaust aftertreatment 1 temperature sensor before diesel oxidation catalyst - voltage below normal value or short circuit to ground

The voltage from the exhaust aftertreatment 1 temperature sensor before the diesel oxidation catalyst is below the normal value, or there is a short circuit to ground. This may affect the proper operation of the exhaust aftertreatment system.

1. 1

   The wiring and connections of the exhaust aftertreatment 1 temperature sensor before the diesel oxidation catalyst

2. 2

   The integrity of the sensor itself

3. 3

   The presence of any damage or corrosion in the affected circuit

1. 1

   Inspect

   Inspect the wiring and connections of the exhaust aftertreatment 1 temperature sensor before the diesel oxidation catalyst for any damage, wear, or poor contact.

2. 2

   Test

   Test the voltage output of the exhaust aftertreatment 1 temperature sensor before the diesel oxidation catalyst using a multimeter to confirm if it is below the normal value.

3. 3

   Check

   Check for any short circuits to ground in the circuit of the exhaust aftertreatment 1 temperature sensor before the diesel oxidation catalyst.
