SPN 654 FMI 4 – Injector Cylinder #4 Needle Control Valve, Abnormal Operation (MIN) Fault Code (Symptoms, Causes & Fix)

The SPN 654 FMI 4 fault code indicates an abnormal operation of the injector needle control valve for cylinder #4. This diesel engine fault code suggests that the Engine Control Module (ECM) has detected a minimum threshold issue with the control valve's operation, potentially affecting fuel delivery and engine performance.What SPN 654 FMI 4 MeansSPN 654 FMI 4 fault code is related to the fuel inj read more

SPN 654 FMI 3 – Injector Cylinder #4 Needle Control Valve, Abnormal Operation (MAX) Fault Code (Symptoms, Causes & Fix)

The SPN 654 FMI 3 fault code is a diesel engine fault code indicating an abnormal operation of the injector needle control valve for cylinder #4. This diagnostic trouble code is triggered when the Engine Control Module (ECM) detects a maximum deviation in the expected operation of the needle control valve, suggesting a potential issue in the fuel injector system.
