I have only found three sensors. I have found the two on both the driver and passanger sides Also, one just after the converter on the passanger side. Am I missing one. I think the one I am looking for is the one after the converter on the passanger side. Thanks for the help.

1-2 is downstream after the passenger's side converter.
First number when talking HEGOs is the bank number that it's on, 1 being the side of the engine with cylinder #1, 2 being the opposite side. The second number is it's position in the exhaust, 1 being upstream, closest to or in the exhaust manifold, and 2 being downstream, after the second converter.
