Default 02 sensor?

I got the infamous CEL. I went to pep boys and they hooked into the obd and it read 02 sensor code: P0139. I popped out the sensors and they looked ok. Should I just replace it or them? I have a 2006 with 45k. My only mod is the K&N fipk.
Thanks!

IMO stock sensors should hold up for at least 100,000km....

that sucks. those sensors are so dam expensive......fortunately i bought two of them used from the For Sale section. i would go there and get one for 50 bux instead of getting on at the dealer for $250+ bucks

have the code reset and see if it turns back on. then maybe you should look into replacing it. i got the same code almost a year ago and reset it. i havent had a CEL since then. i figure that code was a fluke, maybe from me hitting something since im lowered.

you wont be able to tell if an o2 sensor is bad just by looking at it. a good one and a bad one will look pretty much the same. you have to go off what the CEL/obdII tells you

Thanks for all the input! Has anyone experienced an 02 sensor with such a short life?

Heck yea.I've had them fail at under 15,000 on other cars I've owned.Probably one of the biggest TSBs on several makes and models.Overpriced little muthas too... in my most humble opinion or course. Great little "Nader" money makers for the market though.

Someone reply back to me asap, thanks, but anyways. Can you ONLY use Honda OEM o2 sensors? becuhs My O2 sensor went out on me, and basically I went to Kragen Autoparts, and bought myself a Bosch o2 sensor, its not the direct fit one, its the one where you have to do some splicing, I took it to the shop to get it installed, but apparently my check engine light still turned on after being reset. So is there any other route I can go instead of buying $250 sensor at Honda. Thanks Lmk, PM if neccesary thanks.
