Which one. You have 4 on there. Two before the catalitic converter called upstream 02's and two after the cat called of course downstream 02's. depending on the codes as to the placement and the diagnostics. the cats are located on the exhaust side of each head where the cats bolt on to the exhaust manifolds. the front ones you'll find between the raditator and the engine and the back ones are easier to see if you remove the air box and the intake hose with the mass air flow. then look between the firewall and the engine below the air plentum or the intake manifold upper housing. Be careful that you do not replace an 02 sensor just because you have an 02 code. there are other reasons for those codes to be set. Good luck
