legacyak Posted January 5, 2008 Share Posted January 5, 2008 I'm going to replace the front oxygen sensor in my 00 OBW manual transmission. I just got the part from 1stsubaru and checked the OEM number and it checks out fine. However I got digging in my garage and forgot a couple years ago I bought an genuine subaru o2 sensor on ebay. I think it is the rear o2 sensor. The part number is 22791AA00A. Will this part work at all for my car? Quote Link to comment Share on other sites More sharing options...
WAWalker Posted January 5, 2008 Share Posted January 5, 2008 That part number is a front A/F ratio sensor (O2 sensor), for auto trans Outback of your vintage. No use on a manual trans Outback. Quote Link to comment Share on other sites More sharing options...
