BTW welcome to the forum. The "Search" feature, especially the "Advanced Search" tool is very useful. For example, I searched "02 sensor location" and limited the search to the "SC430" forum, not the entire site. I found three responses and this thread: https://www.clublexus.com/forums/sc-...-location.html. In this previous thread, I posted a more comprehensive PDF document and clearer diagram, (comment #2). The document is 31 pages of great info on the operations of your engine. Two diagrams on pages four and five will make it clear. Hope this helps.

place the car on a lift, look at the 2 exhaust pipes coming down from each side of the engine you see each sensor clearly. they screw into each pipe you'll see the wires.
