rustynut2 112 Posted September 28, 2020 Just in case anyone else has this problem, its my 2nd time around. Oxygen sensor is gone again. I replaced it about 2 years ago, but I don't know if it got replaced with the updated part or a new old part. Old o2 part 36531-hr3-a21 New o2 part 36531-hr3-a22 Only lasted maybe 20 miles/2 years. I only use the atv for deer season. Will let ya know how it goes. 2 1 Share this post Link to post Share on other sites
RubiDan 596 Posted October 1, 2020 I bought a 2017 Rubicon not too long ago with only 34 miles and 10 hrs. on it. It wasn't long before my O2 sensor checked out and I got the new A22 part and it's doing fine so far. If I remember correctly it has more resistance than the old part. I bought mine at Partsfish.com and they had the best price that I could find. It took two or three days before they shipped but I didn't have to wait too long to receive it. 1 Share this post Link to post Share on other sites

TBRider 1,411 Posted October 5, 2020 My 17 rubi has about 5000 km and just about 400 hrs I think, I've never had a problem with my O2 sensor Share this post Link to post Share on other sites
