Reading 02 Voltage

[johnovision27]

Just a quick question for you tuning gurus out there. Could you simple read the O2 sensor voltage by hooking up a volt meter to the signal wire and then to ground?
It seems like a simple solution to me, but I want to make sure I'm not missing anything....
Thanks

You would want to measure between sensor signal and sensor ground, not chassis ground.

Awesome. Thanks! Luckly enough I have a multi meter that will shot the peak value SAFCII, here I come!

You should get a wideband... and a real logger...
