Subject:O2 Sensor - 3-wire vs 1-wire
From:John Rodgers
Date:Sat, 21 Jan 2006 11:19:50 -0600

Can the one wire version be used on a 2.1L engine?
If not, why not??
If so, what is lost without the other two wires.

My newly installed  3-wire O2 sensor apparently has an internal fault.

I have a brand-new-in-the-box 1-wire O2 sensor.

Thanks,
