RE: Oxygen sensor and wiring

You're completely correct, of course! there is only one wire so you're
right, guess I wasn't thinking! that wire is sending a signal not receiving
one! duh (do I feel like an idiot?)

    Hmm, I think I am probably wrong, but I believe the only power the
sensor has is generated by a chemical reaction within it.  I know on some
cars there is a reference signal sent through it until it warms up, but ours
does not.  This somewhat knowledge is only for 8V, as the 16V's have a
heated sensor which would have power to the heating element.  Hey, a quick
answer, but not necessarily a correct one.
