02 sensor replacement under way bank 2 sensor 1
Hey y'all,
new member here, first time Lexus owner and first time posting. I'll post more pictures of the car as the projects continue, but right now she is tough.
03 sc440. Code was for bank 2 sensor 1. Eventually I got it unscrewed underneath from the passenger side, and from what I've read it unclips from the interior?? So I have taken out both of the front seats, in order to disconnect the O2 sensor what do I need to do next?

i ask because I was looking at the wiring diagrams and it show the B2S1 staying in the engine compartment.
there are four wires, two go directly to the ECM (HTR, OXR1), located, drivers side under one of the black covered boxes.
the other two (GRD and a shared common with other components) these do not go to the ECM.
try to follow the wires from the O2 sensor.
if you need pics of the manual, let me know.
also, confirm we are talking the same item O2 sensor, passenger side, upstream of cat2, screwed into the manifold.

i may be wrong but I don’t see how the O2 sensor enters under the seat.
can you get under your car and take a picture?

Thank thank you very much, not having all the manuals for this very used car (well over 200k) puts me at a slight disadvantage. I was getting ready to remove the console and it looks as if I do not have to oh, I will keep you updated

Hope I am not too late, but the O2 sensor wire is in the transmission tunnel. Here is a post with both the location and a video of who to change it (Disclaimer, I never watched the video)
