Heated Oxygen Sensor Conversion

[Tim81]

Hello,

I know some of you have converted over to a heated oxygen sensor for various reasons. I'm planning on doing the samething except I'm not sure on how to go about it. Should I get a three or four wire sensor? My stock sensor has two wires that both go to the ECM, so I'm thinking a three wire might not work. Anyways, I would really be greatful for any assistance at all. Thanks Tim

I used the Bosch 3 wire sensor (same as in the C4 ZR1, had a very nice price )

The only difference between the 3 and 4 wire sensor is that the 4 wire sensor has a seperate wire to ground the heating element.
As for the original 2 wire sensor. Yes both so to the ECM but is just grounding it like a normal wire.

Mine works great (as far as I tested it). When putting 12v on the heating element you'll feel it go hot within one minute!
