p0403,p0405 codes.
i was planning on doing an egr delete when i do my oil cooler so i disconnected my egr valve,fired the truck up,drove it around and got no cel.went to re-start and got the p0403,0405.havent had the truck to the dealer in 2 and a half years,at which time they re-flashed it.did i get the "egr insufficient flow" flash at that time?.reason im asking is we have emissions here,but i would really like to delete the cooler.if i delete it and plug the valve back in will all be good to go?, or will i get the p0401 code?.thanks for all the help.

PO401 is for flow [insufficant flow]
and PO402 are for flow as well [to much flow]
you need a tunner if you get the PO401 code to turn off the cel
mine never turned on the cel unplugged or deleated
