Massey Ferguson A.23.25: External Hydraulic Valve 2 Issue

Indicates a fault within the circuit of the second external hydraulic remote valve. Typically caused by a connection problem on the hydraulic valve or an issue with the spool position sensor value.

1. 1

   Inspect the wiring harness and connector leading to External Hydraulic Valve 2 for corrosion, backed-out pins, or wire chafing.

2. 2

   Check the spool position sensor value using a compatible Massey Ferguson diagnostic tool to see if the valve is reading out of range.

3. 3

   Test the resistance of the electronic solenoid on Valve 2 to ensure it has not shorted or opened.

1. 1

   Relieve all hydraulic system pressure before servicing the valve block.

2. 2

   Disconnect the negative battery terminal.

3. 3

   Disconnect the electrical harness from External Hydraulic Valve 2.

4. 4

   If the diagnostic checks isolated the issue to the wiring, repair the harness or replace the connector.

5. 5

   If the spool position sensor or solenoid is faulty, remove the retaining bolts for the Valve 2 slice on the rear remote block.

6. 6

   Replace the faulty sensor, solenoid, or the entire valve slice as dictated by the component failure.

7. 7

   Reassemble, restore fluid levels, and use a diagnostic tool to clear the 0A.23.25 code and recalibrate the hydraulic valve limits.
