I am trying to get my Kia Sportage smogged. The error that popped up was the 2 O2 sensors. I had both replaced according to the code, the exhaust checked for leaks, and ran Sea Foam through the fuel system along with a higher octane fuel. And yet the check engine light keeps coming up the same. Any Ideas?
O2 or HO2S
that is the question
O2 sensors are after the cat converter/s where as HO2S sensors are in the exhaust manifold before the cat converter/s and report exhaust gas composition to the ECM so that the air /fuel mixture can be adjusted
May be you replace the wrong sensors

Ok I think you meant code P0171, this means the fuel trim is always lean, you need to check for a engine vacum leak, maybe a cut or damaged PCV hose or any other hose that is in the vaccum system, I have read other Kia owners (Kia Forums, you should join one) reports of this same code, most found it not to be the O2 sensor but a vacuum leak.

well if you mean iat it is part of the masflow air sensor system witch is on the air intake system may be in witch is hooked to the air cleaner box should round tube with wires going to it any way the code you posted is not right hope this helps
Testimonial: "thanks!"

p0560 is system voltage problem. open or short between the battery positive and the ecm.CHECK ALL FUSES. dosnt matter what they are labeled under dash and under hood replace any that are bad and retry to start. no start then check voltage to ecm grounds to. i dont have a wireing diagram to give you but for a small fee or free the dealer can make you a copy.make sure all the wires that go to battery terminals are not corroded and are making good contact [verified with volt meter]. if after all checks ok then replace ecm. as a side note i havent had to change one ever.
Testimonial: "Thank you for the help. We will continue to check all fuses and wires."
