The oxygen sensor on the 3.4 engine is below the EGR valve. It is in the rear exhaust manifold. Hard to get at though. It is a 22mm special socket so the pigtail comes through, or a 22mm open end wrench (a stubby). Remove your airbox, the rubber air intake hose going to your throtle body, and the heater hose from your intake to your heater core. That should leave you enough room to put your hand through the hole.
The o2 sensor is directly next to the EGR tube.
