We have 101k miles on our '06 S and we got our first CEL, P2A00 and P1172. I think those are for the o2 censer? I know my gas mileage has dropped about 2 1/2 mpg in the last 6 months, could a weak o2 cause this?

That's more than I thought it would be, now I'll have to take it to Honda and see if my car has the PCM update and then buy a new o2 censer.
I think it's the upstream 02 that I need to buy so is the DENSO Part # 2349065 the one I need or should I just bend over and get it from Honda.

Thank You,
