just a generic guess .. as I do not know what engine or vehicle this is .. but so far ...

spn 102 fmi 18 = cummins fault code 125?.

FC 125 = something wrong with the intake manifold pressure sensor (or whats known as the imap sensor on a newer engine) and its indicating that boost pressure is lower than expected.

Fault code 125 is basically a generic "Low Boost" alarm.

That Could be a whole lot of things that can cause this, either in the intake, the turbo itself, maybe in the exhaust, or even in the EGR system.
