New Holland ENG 611 – Engine Controller (ECM / EDC): ECM detected engine initiated protection shutdown or keyed-off while above specific load limit.

This code indicates that the engine controller shut down the engine to protect it from damage (often due to fuel delivery issues, overheating, or over-pumping), or that the operator turned the ignition key off while the engine was still operating under a heavy load.

1. 1

   Check for companion codes on the corner post or instrument cluster (e.g., ENG 449, ENG 452, ENG 456, or ENG 329)

2. 2

   Inspect the primary and secondary fuel filters for plugging, water, or contamination

3. 3

   Check fuel tank venting by loosening the fuel cap immediately after the engine runs rough or shuts down to see if a vacuum is pulled

4. 4

   Inspect the lift pump for loose mounting bolts that could allow air ingress, and check the intake screen for debris

1. 1

   Resolve Venting Issues

   If a vacuum was detected in the fuel tank, clean or replace the fuel tank vent/breather.

2. 2

   Service the Fuel System

   Replace both the primary and secondary fuel filters with new OEM or equivalent filters.

3. 3

   Clean the Lift Pump Screen

   Remove the intake line from the lift pump, clean the intake screen, and reinstall.

4. 4

   Secure the Lift Pump

   Tighten the lift pump bolts to ensure no air is being drawn into the fuel system.

5. 5

   Bleed the System

   Bleed the fuel system to remove any trapped air.

6. 6

   Test Run

   Clear the fault codes and run the machine under a heavy load.

7. 7

   Address Injection Pump

   If the tractor continues to shut down under load and throws CAPS pump codes (like ENG 329) alongside ENG 611, the CAPS fuel injection pump is likely failing and will require replacement or a professional rebuild.
