O2 question

[ziggydub628]

So I've been out of the mk2 game for a while sadly. But when cleaning out my old parts and such, I ran across a single wire o2 from a cis-l (I think) car. Anyway, would I be able to hook up a narrow band af gauge to that sensor? Or is that not how that o2 works.

Anyone?

Curious, but I don't know.

I do know you can check an 02 sensor via voltage, But I don't know is that is resistance you are actually reading since the O2 sensor grounds out on the exhaust. I think .2 volts is way lean and .9 volts is uber rich, but am not sure.

I also know you can use a simple volt meter as an AFR gauge with an LC1 (wide or narrow band, but that doesn't help much.

You should be able to hook up a resistance type gauge and get some kind of reading, but what it actually tells you is a mystery - its all about how things are calibrated.
