Hey guys, I'm new to this forum - but I really like it. I'm trying to find the oxygen sensors in my '04 SC430 - so I searched the forum for "Oxygen sensor" and got several pages of all kind of stuff that don't seem to have anything to do with oxygen sensors. Can anybody educate me on the proper way to search for something specific like this?
Thanks,
Thanks,

hi, is your engine light on? if so have you got the code read? my (b1s1) oxygen sensor needed replacing.. just did it last week!
there are 4 oxygen sensors.
Bank 1 Sensor 1 (driver side before catalytic converter) also called upstream left
Bank 1 Sensor 2 (driver side after catalytic converter) also called downstream left
Bank 2 Sensor 1 (passenger side before catalytic converter) also called upstream right
Bank 2 Sensor 2 (passenger side after catalytic converter) also called downstream right
hope that helps![Smilie](https://www.clublexus.com/forums/images/smilies/smile.gif)

Hey, thanks all - just what I needed. And Bimmer, yes my engine light is on and that exactly the sensor that needs to be changed. How difficult was it to get to - any tips. Also, where did you get the new sensor and what would be a fair prioce? I'm assuming that you bought it online - are there some reputable companies that I should know about - and some I should avoid?

I could not attempt myself as I have construction going on in my garage so I got my mechanic to do it... he stood right under the steering rack and used a long bent nose plier to reach its plug, took him about 10 min just to unplug it because of the all the pipes around the steering rack in the way... then he had a twistable head wrench with a oxygen sensor socket which has a slit for the wire to come out of so the socket can seat on the plug.
now if you dont have a oxygen sensor socket I would just try using an open end offset wrench. But It can be alot easier if you just open up your steering rack (3 bolts), and let it hang, and it will give you enough clearence. Now as for the oxygen sensor, I was told to go for Denso or NGK.. I bought NGK from a partsource store near my house as they claimed that both are same company (not sure
