Can anyone tell me how many oxygen sensors are on a Gen 3 Sable. One person told me two, someone else told me four.

There are only 2 that i know of. one in the intake pipe, and on in the exhaust system.

My gen3 has 4 o2 sensors. Two before the cats and two after after the cats.

I could be wrong, but then again i haven't removed or done anything to the cats.

This is right off the Ford DVD manual...... Looks like 4. Like the Gen 4 have.

OBD II cars have one before and one after the cat. The one before the cat does all the work as far as reporting back to the PCM about the fuel mixture. The one after the cat monitors the cat's functionality. Seldom is the one after the cat bad.
