Case IH 3368 – Engine Control Unit (ECU) / Engine Controller: Fueling Limited Due To Other Engine Fault Detected, See Other Fault Codes

The engine control system has intentionally limited fuel injection (and thereby reduced engine torque/power) to protect the engine or to comply with emissions regulations due to the presence of another primary fault code.

1. 1

   Connect the CNH Electronic Service Tool (EST) or a compatible diagnostic scanner

2. 2

   Read all active and stored fault codes in the Engine ECU

3. 3

   Look for the primary fault code(s) that triggered the OBD performance limiter

1. 1

   Retrieve Codes

   Connect your diagnostic tool and pull the full list of active fault codes from the Engine ECU.

2. 2

   Identify the Root Cause

   Disregard code 3368 temporarily. Identify the other active engine or emissions-related fault codes present in the system.

3. 3

   Perform Primary Repair

   Follow the OEM service manual troubleshooting steps for the primary fault code(s).

4. 4

   Clear Codes

   Once the physical repair for the primary fault is complete, use the diagnostic tool to clear all fault codes.

5. 5

   Verify Operation

   Start the engine and perform a test run. Once the primary fault is resolved and cleared, the ECU will lift the fueling/torque limitation, and code 3368 will automatically resolve.
