Answer
The air/fuel ratio sensor is located in on the exhaust manifold, on the 4 cylinder engine it's located in the manifold near the radiator, it has a wire with an electrical connector on it. If it's a V-6 engine it's located on the exhaust manifold hear the firewall and a little harder to grt to, it also requires a special socket to remove it. The sensor should be replaced in either case but you can cheat a little, just before going to have it tested again disconnect the negative battery terminal for about ten seconds, it normally takes a while for the light to come back on you might make it through, good luck.
