Review: Resolved the computer code and Service Engine Light. Pretty easy to replace with just metric ratchet set, metric wrench and mallet. Hardest part was getting the old one off. Tried PB Blaster, but not sure that helped. Tried running the engine for awhile to get it nice and hot (be careful under there when it is hot, easy to get a nasty burn). I think the heat may have helped along with a mallet to pound on the wrench handle. Either that or just persistence. Comes with a bit of anti-seize compound. All the attachment clips fit exactly which is great because these are always a bear to get off without breaking. In this case can just cut and grab without having to try and save them. Highly recommended to fix this sensor code.
Review: This sensor was exact fit for my 2006 Lexus RX330, its been working perfect for several months months now. Definitely recommend.

*by H***G on 25 December 2021*

It came in different Denso Part # on the unit. May be new update from Denso. But it fixed our 2004 Lexus RX330 code P420 Bank 1 (by fire wall side). Don't change the cat converter first, change this first!
