Need a Part number

[Shadowfax]

Anyone know where I can get the GM part# for the o2 sensor that is on the back of the Cat converter? I got a SES code and had it taken to autozone last night to get the diagnostic check and it came up with that. Any help is appreciated.

 

BTW Truck has the 4.3 in my 03 S-10

Nevermind, a buddy I pmed got it for me. Part # is 12567254 if anyone else needs it.

On an '03, wouldn't this be warranty?

[Shadowfax]

03 model bought in the end of 02. Warranty expired cause I exceeded the miles on the warranty in less than a year..... Yes I travel a lot of miles lol.

If the O2 sensor does not fix it check your fuses. Frank S. just replaced his O2 sensor and it kept throwing codes for the O2 sensor. Turns out it was a blown fuse. Go figure..

[Shadowfax]

Cool, thanks for the tip.

 

Gotta love the S-10 though, takes a beating keeps on tickin. My other one is still running after I sold it to my cousin. Hes up to 300k on it now, and when I sold it to him it was at 265k. Ran like a charm too.

 

Shame they killed the line

It's also recently been brought to my attention that emission system parts should have an extra warranty on them,something like 5 year/80k miles.

 

You may want to check on that before installing if it isn't the fuse that I still can't find anyone who knew it existed besides a shop.

96+ 4.3's 5.0's and 5.7's all have 4 o2 sensors

Is it just the O2 Sensor or is your cat bad?

[Shadowfax]

Nah just the sensor. Had it checked out with the diagnostic computer and it threw a code for the sensor at the rear of the cat.
