We have a 2017 International MaxxForce that has been deleted and is throwing a couple codes: SPN 334080 FMI 4 and SPN 69788 FMI 27. Obviously these are codes that didn't get wiped when the delete happened, but the truck loses power on hills because of it.
Google searches turned up 334080 as the EGR flow, but I can't find SPN 69788 anywhere. Anyone have some insight?
