well, since it appears no one has replied, if you haven't found it yet, it is in the engine pipe going down to the catalytic converter, look along the pipe up near the flange from the bottom of the car. wire is about 6-8 feet long, and runs to a near the back of the tranny.

Actually there are 4 o2 sensors on the V-6 MPV 2 in the front and 2 in the back Front and rear upper sensors are on the exhaust manifold and the lower front and rear o2's are in the exhaust pipe just below the upper o2's
