My 1994 22re 4x4 has only one 02 sensor and Im assuming it was before the Cat. The previous owner removed the cat. I found denso 02 sensors online but want to make sure I get the correct one. Can anyone help me out?

 

Think how much easier it would be to get an answer to this question if you just asked what you wanted to know? Or if you provided some links to the sensors you thought were correct?

I'm assuming you want a Denso part number. It depends on your drive-line. Here's "the horses mouth": http://densoautoparts.com/find-my-pa...icle-selection

 

It comes down to just what you have .

California Emissions package or not ??

Long bed or short.??

Do you want the universal one that you put your plug on or a plug and play one. The length of the pigtail

The one for behind the cat has a longer pigtail.

That is really pretty much what the differences are between part numbers.

There was a thread about this some place.
