It's somewhere in your map sensor connections. Juice to map, map to juice, or even if you have a boost fooler in there also. Seems to happen to some guys after they wash thier trucks, and get things get a little damp, but I'm betting it's in those connections. Take them apart, clean them up, and use electrical grease. That dang code won't clear either, so I always had to shut the truck off, sometimes 2 or 3 times to get it to go away.
