P0455 and P0457 are not O2 codes, they are evap codes. You have a major leak in the evaporative emissions system. P2247 is an O2 code, but not necessarily a bad sensor. Read these 3 links:

Dealership spent two days on this. They say it is wire problem. probing into harness and such. Gonna take three days to track it down. Not so sure I agree. Seems dealerships have lost all their TRUE diagnostic personnel. Telling me that older wires get brittle and crack.... WHAT ? I dont know,,,,but I got wires that are over 60 years old and they aint cracked yet......Thoughts?

negative.... drive truck 10hours a day. I'm doing repairs myself now/and forever more....Enough with the millineum kids with no (or meaningless instruction) Only reason went to dealership was lack of time on my part.....

Update: After visiting dealership that had my truck:
The "mechanic" had disconnected EVERY wiring harness trying to find a "short" (should have been looking for an "open") hence, requested my truck back before any permanent damage was gonna happen. Got truck home. Sacrificed some time to fix it. pulled all four sensors and bench tested them. Found 1 was inop. Replaced it with a new one from ebay @ $85.00. Truck runs again like a champ with no codes AT ALL ! Thanks for the wasted 4 days dealership....
I just wanna know .......Whos instructing these new up and coming tecs...? Good think I taught my son well, cause in the next few years there's gonna be no one to fix anything......

Hey, Hope may be on the horizon. Soon as I posted the previous a news story popped up. The auto mechanics guild recognized the shortage of qualified mechanics and is now sponsoring contests to attract the 18 to 35 year olds into the field. A team of two, an 18yr and 17yr old won. They had to be the fastest to diagnose and start their vehicle with 12 issued. CONGRATULATIONS TO THEM. They received a scholarship to mechanic school. Finally the industry is catching up. YEAAA !
