Jeffstpetebeach Posted August 19, 2009 Share Posted August 19, 2009 Hello, I have a question to ask. I pull out the front oxygen sensor and it has Denso part # 480467-48010, than I pull out the next one and it has Denso Part # 89467-48011, Are these two different Parts I thought the two manifold oxygen sensors were the same part. Lexus # 234-9009. By the way 1999 RX300. Thanks for your help on this. Thanks Jeff :D Quote Link to comment Share on other sites More sharing options...

The one downstream from the CAT is the different one. Quote Link to comment Share on other sites More sharing options...

I pulled the bottom one and that one was the one with part # 89467-48011. The sensor just didnt want to move Top one. thanks for your time Quote Link to comment Share on other sites More sharing options...

Don't know that there's any difference between 'em, they just changed the # 1 digit. The 234-9009 is the same sensor with the Denso # because the other #'s belong to Toyota. Even the OX sensor (the 1 back by the Cat. Conv.) has the same threads, it just screws into the plate that bolts onto the pipe. What Blueridge meant is the downstream one is different in that it is an Oxygen sensor and the front ones are A/F ratio sensors. Quote Link to comment Share on other sites More sharing options...
