The SPN 2659 FMI 18 fault code is a diesel engine fault code indicating an EGR Flow Target Error due to low flow. This diagnostic trouble code is triggered when the Engine Control Module (ECM) detects that the actual EGR flow is significantly lower than the target flow. This discrepancy suggests a problem within the EGR system, which is crucial for reducing NOx emissions by recirculating a portion
