Engine Codes

[goXtreme]

I went to start my truck this morning and it fired imediatly, but was very slow to rev up to idle speed, once it got there it ran fine, but the CEL was on.

I hooked up the Bullydog and got three codes:
U002
P0401
U2205

I did a search for engine codes on here and couldnt find them, I did find on one thread that the P0401 is "EGR flow insufficient", but that is all I could find.

I recall reading a thread on here that had a bunch of codes listed, could someone hook me up with a link to that?

If not, can someone tell me what the other two codes are?

Thank you!!

The Ucodes are body related. The U002 code is missing a number. Bullydog tends to generate U codes for nothing. The egr flow is the only one to be concerned with

Body codes, as in like say...Fenders? I am not understanding.
The EGR code went away with the Bullydog, so for now I am not woried about that, I will be doing a delete on it soon anyways.
Thanks for the info

Body codes generally relate to things like airbags, cruise control, dash errors, stuff like that
