The SPN 2623 FMI 2 fault code is a diesel engine diagnostic trouble code that indicates an "in-range" fault with the accelerator pedal position sensor. This code suggests that the Engine Control Module (ECM) is receiving a signal from the accelerator pedal that is within the expected range but is still considered faulty, potentially due to inconsistencies or unexpected behavior in the signal.
