Truck says SPN-102 FM 17 Boost pressure
Insite : same code data valid but below normal operating range

I sent you an updated version of your file that includes the update.

Thank you very much sir!

Well it threw the same code again at the same point on the same pull. Now I’ve got a new code SPN 157 FMI 18 Injector metering rail 1 pressure-data valid but below normal operating range. Says it was just over 3000 psi under commanded pressure. Again no loss of power but it is running rough at idle and engine brake losses performance until I clear the codes. Everything is fine until the first big pull.
