Anyone know what these codes mean?

My check engine light recently came on, and my gas mileage has dropped 3-4 mpg since. I ran the codes and got these two:
P04F5
P2C11

Anyone know what these mean? I figured that they might be O2 sensor/exhaust related. Thanks for the help.

Hmm, I'm not sure then. The guy at AutoZone ran the codes twice and it read the same thing both times. Do those closely resemble anything that would affect gas mileage, like O2 Sensors?
