I thought these sensors were part of the emission control system and were
warranted for 100,000 miles. My "check engine" just came on in my Blazer
with 27,000 miles on it. I found 2 sites that talk about testing and
repairing. If their not warranted, I sure don't want to go to the dealer and
get ripped. I'll try and check it myself.

Subject: Re: [Chevelle-list] OT: Universal O2 sensors
I have two in total and they're both gonzo. Denso is the OEM brand and the
most expensive. They list only one part# for both. Walker's are $95 each
for "OEM-style" (with wires & connector) and oddly enough they list
seperate part #'s for b4 and after the cat.
The universal ones are anywhere from $20 to $35 each on partstrain.com
but I have to go out to the car and verify whether mine are one, two,
three, or four wire. For some reason they all come up as fitting my car
but that can't be true.
Quoting [EMAIL PROTECTED]:
Ouch, 129 bucks. I want to say mine was roughly 40 bucks. I even
bought it from Auto Zone. If you have two throwing codes, I would
replace all of them. My truck has 3 total I think. One on the exhaust
manifold, before cat, and after cat.
