If anybody has some *good* o2 sensors they would like to throw my way, give me a little tap on the plastic keys and shoot me a reply.

Do you want pre cat or post cat sensors? What year truck? 3 wire or 2 wire sensors?

ooooh, that's a good question. The ones I need when the "Service Engine Soon" light comes on.

The truck's a 99 NBS ext cab sierra. 1500.

Honestly I can't answer any of the other questions tho. I really forgot to ask the mechanic guy after I had him read the service code. :idiot: <----me

sorry

LOL....well a code can be thrown for both pre cat and post cat sensors. You need to know which one....for instance a code regarding:

bank 1 sensor 1 is driver side pre cat
bank 1 sensor 2 is driver side post cat
bank 2 sensor 1 is pass side pre cat
bank 2 sensor 2 is pass side post cat

Figure out which one and change it....I also wouldn't get used sensors (probably not many around anyhow...lol. Pick up new ones:read:

okay, figured out which sensor to buy. btw, is it possible for just one o2 sensor to go? 'cause the codes that were thrown was for the pass side pre cat sensor. :shrug:


I just don't know.......

Yes, one sensor can go....

Secondly, where did you get a quote for $80? Check pep boys or kragens' or whatever is near you. They will have the best prices usually.

They ain't cheap....Cameron
