I did look on Google, but I don't really understand the diagrams. The only pics I found were for older RX's

Thanks for your help!

It seems a bit of a pain to remove. The clip is hidden, so I had to follow the wire with my hand. Also the sensor is not easy to undo without an O2 sensor tool. I'll probably give it a go on Friday when I am off work. Hopefully that will sort out the P0051 code I have. Also hope the sensor I bought is the correct one.

Heres a couple of pics. I have zoomed in where I think the sensor is.

I'll get one when I am at home later on today. Thanks for your help.

Thanks for the link. I'm not very good at reading engine diagrams, so I'm still none the wiser. I'm a beginner when it comes to fixing cars, I'm afraid.

Just got myself a Lexus RX300 after being a strictly German car man, however I may now be becoming a convert! You certainly get a lot for your money. Does anyone know where the Bank 2 sensor 1 is located on RX300 2004?. I think I have found it, but I need to make sure I am removing the right sensor. All other information I could find related to pre 2004 models and the engine lay out is not the same. If anyone is able to get a picture of the sensor location. that would be great. Thanks in advance for your help.
