If you put "O2 sensor RX 300" into your search engine, then select images, there are lots of schematics showing you where all the sensors are.

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.
