P0191?

Got in my truck and had the check engine light on and the display said Engine Power Reduced. I ran it to the dealer and came back with the P0191 code. Our city is fairly small so the dealer has not seen many 6.7's, so i think the mechanic is learning a little as he goes. Anyone dealt with this code and issue yet? Just wondering how long I am out of a truck. Still LOVE my 6.7.

Hi there. I just looked it up and that code indicates fuel rail pressure. If you search this site I seem to remember others with similar issue.

I did a search and did not see anything in the 6.7 forum other than the list of DTC's. I am more curious about 6.7 specific issues over the others, since that's what I have and am concerned about. Thanks for the input anyways.
