SOURCE: Where is the O2 sensor located on a 2002 Sportage?
it should be located on the exhaust blow the exhaust manifold. on this year car you may have two O2 sensors an upstream located before the catalytic converter and a downstream located after the converter. hope this helps

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.

a wrench and just unplug the sensor wire and screw out and install new one. they make a special socket but i just use a wrench.

check the belt,if its out it will flag up this code,your car will run on sequential firing from the crankshaft sensor,failing that put an oscilloscope on the signal wire at the sensor and ecu its possible the ecu might not be seeing the signal,start with the basics first
