This is mainly on the same subject but a little different.

Are the various O2 sensors 1, 2, 3, 4 wire all interchangeable as long as
it is wired correctly?  It seems that they all put out the same voltage in
the same situations from what I have been reading.  My car has a one wire
O2 sensor which runs for around $130.  Since it has 100k miles on it, I am
looking to replace it.  Granted, I know it needs to fit properly but my
first question is the electrical compatibility.

Also, what is the difference between a normal O2 sensor and a wide band
version?
