Massey Ferguson 001761.11 – ECU: DEF Tank Level Sensor Issue

Issue description

The system has detected a general error with the Diesel Exhaust Fluid (DEF) tank level sensor or its associated circuitry, as reported by the Engine Control Unit (ECU) within the AGCO SISU POWER EEM4 system. When this fault is active, a warning lamp typically illuminates and engine power may be reduced after a certain period due to it being an emissions-related fault.

Check the cause

  1. Using a diagnostic service tool, verify the fault by saving the error log, clearing the code, and performing a system reset (turn ignition off for at least 60 seconds). Operate the machine to see if the code reappears.

  2. Visually inspect the wiring harness and connectors between the DEF tank level sensor and the EEM4 control unit for damage, corrosion, loose connections, or chafing.

  3. Use a multimeter to test the continuity and resistance of the wiring to check for open circuits or short circuits to a high source.

  4. Check the operation of the DEF tank level sensor by testing its output signal to ensure it is within the expected range.

Repair steps

  1. Isolate the fault

    Follow the diagnostic checks to determine if the fault lies with the wiring harness or the DEF tank level sensor itself.

  2. Repair wiring

    If the wiring harness is found to be damaged, shorted, or open, repair or replace the affected sections. Ensure all connections are clean and secure.

  3. Replace DEF tank level sensor

    If diagnostic checks point to a defective sensor, replace the DEF tank level sensor located on top of the DEF tank.

  4. Clear faults and verify repair

    After replacing the sensor or repairing the wiring, clear the fault codes from the ECU. Run the machine to ensure the 001761.11 fault code does not return.
