O2 Sensor

i am wondering if there is a reliable way to check the O2 sensor on a
89 pontiac sunbird 2.0 OHC. i have read about a few different ways, but
they all say you need a GOOD multimeter. my meter is not that good, it
does quite alot and got me though my electronics course in college, but
it isnt high impedence. any help will be greatly appreciated.

    Scan it or  a scope to really see activity or replace it, they are cheap on
    your car.

    It’s only about $30 or something like that and if it’s been in there a
    long time, the one you have is probably lazy. Personally, I do not
    change mine unless I have the code for it. This sensor is one that
    provides a pretty clear warning when it’s not cycling properly.
    As you found out, there are ways to check it though. The impedance of
    your meter is not what’s stopping you.

    Call around to some garages and find out who’s offering "Free" (lmo)
    computer
    "scans" and go get one.  Try to use an independent and stay away from
    so
    called "Chain Stores".
    (You’re more likely to get good results if the guy holding the scanner
    didn’t
    quit Burger King last week to become a mechanic)

    I’m doing about 5-10 a week….no charge.
    wanna take a ride to Pensacola?   :)

    any whooooo……
    a scan and data check only takes about 5 minutes, it’s not that
    complicated, and
    more and more shops are starting to realize that charging for the
    initial scan
    a tatamount to being a "RIP OFF".  jmo

    thanx for the advice, this car is pre OBDII so i can actually do the
    scan my self with a jumper wire. i actually work at a parts store up
    here in canada, and your right they are very cheap, i just didnt want
    to waste money if i didnt have to. it has been in there for well over 2
    years, so it proably does ned to be changed. this weekend i might just
    pull out the torch andmeter for some fun and test it, but ya i think im
    gonna invest in a new one.

    thanx again
