Massey Ferguson 0B.01.05 – Mid Mount Valve Module: Loader Mid Mount Electro Valve Solenoid Low Amp Draw

This code indicates that the electrical current (amperage) flowing through the solenoid circuit for the loader's mid-mount electro-hydraulic valve is lower than the expected threshold. A "Low Amp Draw" typically points to high electrical resistance in the circuit, which is most commonly caused by a failing solenoid coil, a loose or corroded electrical connector, or a partially broken wire in the harness.

1. 1

   Inspect the wiring harness leading to the mid-mount valve block for chafed wires, pinched harnesses, or physical damage

2. 2

   Disconnect the electrical plug at the affected loader mid-mount solenoid and check for water ingress, dirt, or corroded pins

3. 3

   Measure the resistance (Ohms) across the two pins of the solenoid coil using a multimeter to check for an open circuit or abnormally high resistance

4. 4

   Check for continuity between the solenoid connector and the Mid Mount Valve Module to rule out a broken wire in the main harness

1. 1

   Power Down

   Turn off the tractor and disconnect the negative battery cable to prevent short circuits.

2. 2

   Locate the Valve

   Locate the mid-mount electro-hydraulic valve block. Identify the specific solenoid throwing the code (often determined by actuating the joystick to see which loader function is unresponsive).

3. 3

   Disconnect Wiring

   Unplug the electrical connector from the faulty solenoid.

4. 4

   Remove the Solenoid Coil

   Remove the retaining nut at the end of the valve cartridge stem. Slide the faulty solenoid coil off the valve stem. (Note: You usually do not need to open the hydraulic system or remove the valve cartridge itself, meaning no fluid should leak).

5. 5

   Install New Coil

   Slide the new replacement solenoid coil onto the valve stem. Install and tighten the retaining nut to secure it.

6. 6

   Reconnect

   Plug the electrical connector back into the new solenoid. Reconnect the battery.

7. 7

   Clear Codes & Test

   Use a compatible diagnostic tool to clear the 0B.01.05 fault code. Start the tractor and test the loader joystick to ensure full functionality and verify the code does not return.
