xB engine lights and codes
 

The engine lights on my 2005 xB have been lighting on and off for years, but I was always able to get it passed for inspection, but now I can't get it to go out now. I took it to Autozone and blew 5 codes. They are P0012, P0138, P0441, P0442, P0446. Anyone have any ideas? The car runs great, same gas mileage as day I bought it. I have a tremendous mechanic willing to work with me, so any suggestions are welcome.
Thanks
