RemcoW Posted April 18, 2009 Share Posted April 18, 2009 My daughter's Forester threw the P0130 code so thought I'd replace the front oxygen sensor. The replacement sensor the dealer sold me looks like it has been used in that it is blue and it has anti seize on the thread. Is this how they come now? ^That looks used to me but it is said to be brand new.. Quote Link to comment Share on other sites More sharing options...
greenleg88 Posted April 18, 2009 Share Posted April 18, 2009 i do believe that blue stuff is normal.. but idk about the anti seize.. maybe its just a nice gesture =D hah Quote Link to comment Share on other sites More sharing options...
lostinthe202 Posted April 19, 2009 Share Posted April 19, 2009 The last O2 sensors I bought had anti-seize compound on them. Not sure about the discoloration. Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted April 19, 2009 Share Posted April 19, 2009 The antiseize comes on there just like that on the genuine sensors. The bluing looks a little more than usual maybe but how's the wiring and connector look? The dealer probably wouldn't knowingly sell a used sensor, but you know some people, they'll buy a new sensor, clean up their old one and put it in the box and try to return it.

lostinthe202 Posted April 19, 2009 Share Posted April 19, 2009 The more I look at that picture, I'd say it was a new sensor. Doesn't look like a wrench has ever been on it, and it if had been installed and returned, it wasn't on the car very long 'cause that thing is spotless and while I've never tried to clean up a used O2 sensor, I seriously doubt you could get 100k O2 sensor to look that good.

EVOthis Posted April 19, 2009 Share Posted April 19, 2009 that is def. a new sensor..that anti seize is the give-away for me....Also as others have mentioned it doesnt look like anyone has ever had a 22mm on it... Quote Link to comment Share on other sites More sharing options...
ron917 Posted April 19, 2009 Share Posted April 19, 2009 Looks new to me, too. Every new O2 sensor I've purchased has had antisieze on it. That antisieze is in a glob, not smeared as if it had been screwed in. The tip is clean (would be black if used). Looks like the hex had never seen a wrench. And the gasket is not crushed.

nipper Posted April 19, 2009 Share Posted April 19, 2009 Thats new. the antiseeze comes with it, and the blueing is from welding on the shield. nipper Quote Link to comment Share on other sites More sharing options...
RemcoW Posted April 19, 2009 Author Share Posted April 19, 2009 (edited) I just never seen the blue-ing before - of course, I've only only ever replaced three sensors in my lifetime. Thanks for all the input, quys. Edited April 19, 2009 by RemcoW Quote Link to comment Share on other sites More sharing options...
Hondasucks Posted April 20, 2009 Share Posted April 20, 2009 Yeah, that's a new sensor, I've done enough of those + Toyota ones, that anti-seize stuff comes on them (There is usually a little plastic collar that goes over the threaded part to protect it in shipping). Also, I'm not totally 100% sure since I can't look it up from home, but I think there is a ECU reflash that covers a P0130 code, don't know for sure though, esp. without knowing the year of the vehicle.
