Default Re: EGR Flow Insufficient (PO401)

yeah whats weird is, the truck has been running fine as far as i can tell... but one day i got a 402 excessive flow, then now i am getting several 401 insufficient flow..... i keep clearing it with my Flashpaq, but it comes back every day or so. Can i check this in the data logging section of my flashpaq? I know i can view and monitor air intake, mass air flow, and etc.. but i cant seem to find anything with the DPFE or EGR.
