New Holland 19805: Invalid temperature data in the urea tank considering the pump unit temperature - high

The system detects an invalid temperature reading in the urea tank, where the temperature is reported as too high. The temperature sensor in the tank (reagent temperature - solution in the tank) is providing a signal that indicates a short circuit to a high voltage source.

1. 1

   Inspect

   Inspect the temperature sensor in the tank (reagent temperature - solution in the tank) for physical damage or signs of overheating.

2. 2

   Test

   Test the temperature sensor in the tank (reagent temperature - solution in the tank) for proper operation using a multimeter or diagnostic tool.

3. 3

   Check

   Check the wiring and connections to the temperature sensor in the tank (reagent temperature - solution in the tank) for any signs of damage, corrosion, or loose connections.

4. 4

   Replace

   If the temperature sensor in the tank (reagent temperature - solution in the tank) is found to be faulty, replace it with a compatible component.
