New Holland 19802 – New Holland Dosing Control Unit Dcu: Urea Tank Temperature Not Plausible with Pump Module Temperature

The temperature reading from the urea tank is not consistent with the temperature reading from the pump module. This discrepancy has triggered a communication timeout related to the temperature sensor, which is connected directly to the system.

1. 1

   The temperature sensor connected directly to the system

2. 2

   The communication link between the urea tank and the pump module

3. 3

   The signal integrity between the temperature sensor and the control unit

1. 1

   Verify the connection of the temperature sensor

   Check that the temperature sensor is properly connected and not damaged.

2. 2

   Check the communication link

   Inspect the communication link between the urea tank and the pump module for any faults or disruptions.

3. 3

   Test the signal from the temperature sensor

   Use a diagnostic tool to test the signal from the temperature sensor and ensure it is functioning correctly.
