What year and engine do you have.  Sounds like you are testing it
wrong. The 2.1's have three wire hook up.  The double connector is
for the (o2) heater.  Test the single wire to meter and other meter
lead to ground.  At idle it should bounce around alot between .45 and
.7 volts.  No or low reading is either a bad o2 sensor or very lean
running engine.

If you haven't replaced the sensor in 122,000 miles I'd recommend it.
Your mileage and performance will probably improve.

Tnx

Subject: oxy sensor check

Hello all, As my oxy sensor light had came on 122,000+ miles I thought I'd
check the oxy sensor after I changed my oil yesterday. It measured across
the two prong plug 0 volts dc, even after warming up. I was told its
supposed to measure .5 -.7 volts dc, so I guess its time for a new oxy
sensor or was I measuring wrong?
Thanks, Tony
