What is XCMG XE490D (CM2250) Fault Code 2367?

Fault Code 2367 indicates an Injector Cylinder #7 - Mechanical System Not Responding Properly. This Cummins CM2250 engine fault occurs when the Engine Control Module (ECM) detects that the fuel injector for cylinder 7 is not responding mechanically as expected during commanded fuel delivery events.

This code specifically monitors the injector's physical response through fuel rail pressure feedback and internal ECM calculations. When the injector fails to open, close, or meter fuel correctly, the ECM logs this fault to prevent engine damage and excessive emissions. For the XCMG XE490D excavator running the CM2250 engine, this is critical because injector malfunction directly affects power output, fuel efficiency, and can cause severe engine imbalance leading to vibration and component wear.

Common Symptoms

• Check Engine Light (CEL) illuminated on the instrument cluster with possible amber warning indicator
• Noticeable power loss or rough idle, especially under load during digging or lifting operations
• Excessive black or white smoke from the exhaust during acceleration
• Engine derating into reduced power mode (limp mode) to protect internal components
• Increased fuel consumption and difficulty maintaining consistent RPM under hydraulic demand

Potential Causes

The most common technical failures triggering Code 2367 on used XCMG excavators include:

• Mechanical injector failure - internal sticking, worn plunger, or seized needle valve (common after 8,000+ hours)
• Contaminated fuel causing injector bore scoring or deposit buildup on injector components
• Faulty injector solenoid or broken return spring preventing proper mechanical actuation
• Wiring harness damage at the injector connector, particularly where harness rubs against valve cover or engine block
• Low fuel pressure from failing fuel transfer pump or restricted fuel filters affecting injector response
• ECM injector driver circuit failure (less common but possible on higher-hour machines)

How to Troubleshoot and Fix Code 2367

Step 1: Verify Code and Perform Cylinder Cutout Test Connect Cummins INSITE diagnostic software or compatible scan tool. Perform an electronic cylinder cutout test - when cylinder #7 is disabled, symptoms should not change if the injector is already non-functional. Record active and inactive codes.

Step 2: Inspect Injector Wiring and Connector Visually inspect the cylinder #7 injector connector and harness. Look for corrosion, bent pins, oil contamination, or harness chafing near engine mounting brackets. Use a digital multimeter to check injector solenoid resistance (typically 0.3-0.9 ohms) and compare to specification. Check harness continuity to ECM.

Step 3: Test Fuel System Pressure Install a fuel pressure gauge at the fuel rail. Verify fuel pressure meets specification (typically 30-40 PSI at idle). Check for pressure drop during cranking, indicating potential high-pressure fuel pump or injector internal leakage issues.

Step 4: Remove and Inspect Injector If electrical checks pass, remove cylinder #7 injector following proper torque sequence. Inspect for carbon buildup, scoring on the nozzle tip, or physical damage. On used excavators with 6,000+ hours, injector replacement is often more cost-effective than rebuilding. Always replace injector seals and copper washers during reinstallation.

Step 5: Clear Codes and Perform Injector Calibration After repairs, use INSITE to write new injector trim codes if installing a replacement injector. Clear fault codes and perform a test run under load to verify repair.
