I'm not sure about your codes, but I'm guessing they are referring to your fuel pressure regulator. Pull the vacuum line off and see if there is fuel in it, or measure your fuel pressure at the rail. Others may chime in here-- my experience with this is limited to RWD Volvos...

There's a very good chance that your 02 sensor is fine and is just telling the truth about how much 02 it is seeing...
