Emission systems codes P0171 and P0174 on 2007 Acura TL

I recently took my car into a shop to replace the high-pressure brake fluid hose because it was leaking. I guess the repair was quite extensive and the technician had to remove a bunch of stuff (I don't know what) in order to get at the hose. When I got my car back these two codes were present. What's your best guess as to what might be causing the codes?
