Does this look like a Normal O2 sensor?

[cvc7chris]

Idk if it's time to replace or not. i got it out today to paint my Rusted Heat shield Cover and i took the o2 sensor out.

Does it look normal? or old? or what.. idk




BTW this is the Final Product of my Heat Shield
Looks good..better than Before

That looks pretty good, mine was stark white when we took it out, was running too lean at some point.

well i wanted to make sure it wasn't severly burnt or nothing...

can u pull the o2 out and hit it with some carb cleaner or will it damage it?

idk i wouldn't try it..those things are expensive

it's still good as long as you are not throwing a check engine light for it. later.

why mess w/ the O2 sensor if theres no light or you aren't getting bad gas mileage? Those things are pretty fragile so once its in there, you should just leave it and not mess w/ it. It'll tell you when its time to get a new one by throwing either a CEL or your gas mileage will also let you know.

You could also test it when its on the car. You have to start the car, let it warm up to proper operatiing temp and then unplug it and test the pins w/ a multimeter. Its outlined in the Haynes manual somewhere.

plus i thought i needed to remove the headers to change my oil pan..(WRONG!)

Really? I replaced my sensor when I had to pass my emissions test a while back. i got great gas mileage for about 2days....then it all went to poop. I get about 220-230miles per TANK. So I should replace it with a factory O2 sensor? The one thats in there now is some off brand. What do you think?

Stick with OEM or NGK brand, one in the same. Do not get Bosch and other brands, don't seem to work consistently and reliably. I personally have had bad experience with a Bosch unit, lasted 2-3 weeks before it went bad, replaced with OEM NGK and no problems since on my bro's car/90 Accord EX 5spd.

Yeah, some people have good luck with the Bosch or other cheaper ones. But its common to hear people who've used the Bosch or such and they fail soon or never work right at all.
NGK or Denso is nearly always recommended around here. One or both are OEM, and they do cost more, but it seems most worth it. Some of us are running near or more than 200,000 miles on the original O2s and still gretting great MPG and passing emissions just fine.

Oh, ok.....thanks guys. Yeah, I'm almost at 300k on my CB and I really need it to not eliminate a tank of gas in 230miles. Better gas milage here I come!!!!
