John Deere 005126.03: Sensor Supply Voltage Too High

The system has detected that the supply voltage for the sensors is too high. This may affect the accuracy or operation of the DPF Pressure Differential Sensor, DOC/DPF Temperature Sensor, SCR Temperature Sensor, and DEF Pressure Sensor.

1. 1

   The power supply to the sensors

2. 2

   The wiring and connections to the sensors

3. 3

   The voltage levels at the sensor terminals

1. 1

   Verify

   The voltage supplied to the sensors using a multimeter or voltmeter.

2. 2

   Inspect

   The wiring and connections for any damage, corrosion, or loose contacts.

3. 3

   Check

   The power source or circuit that supplies voltage to the sensors for any faults or overvoltage conditions.
