Mr Wizard question on O2s

[Catwood]

On an O2 sensor are the two white wires the heater circuit?

There is a gray and a black but I don't care about those at the moment.

I think the two white wires should show some resistance (1-2 ohms) while everything else shows open.

Thanks,
Carl

What kind of a problem are you having??
On the HARNESS side of the O2
The front O2s heater wire + from the ASD relay, color is DGrn/Org
on the rear sensors heater + wire is Or/DGrn
BLK is ftr heater ground and BLK/Tan the rear heater grounds
The sensor grounds are BK/wht stripe and sensor signal to PCM are the RDor LtGrn or wht or PK striped wire.
Hope this helps

No it's not!


I'm measured resistance between the white wires. One sensor showed opened while the other and an old spare showed 1-2 ohms. I was trying to figure out what circuit the two white wires were.
