2008 gmc sierra keeps giving me a P00FF code...whats that code for

Question

this truck had mice inside of it, we got the mice out of the truck, fixed ALL chewed/damaged wiring....and now that everything is fixed it keeps setting a P00FF code and idles at around 3000RPMS randomly.....what does P00FF even stand for??? when the truck came into our shop it did not set this P00FF code, but now that all other codes and problems are fixed it instantly sets the P00FF code

Answer 1

P00FF Fuel / Air auxillary system

This is not a code but a general information, it should be accompanied by a regular dignostic trouble code. Just as P0700 is is a infomative code for the transmission so is P00FF, you see this code mostly on Launch Tablets. Maxidas, and some Autel scan tools, it the way some scan tool read.
