Have to replace B1 S2 (passenger side, post cat.) Oxygen sensor. Looking for the procedure with pics. Any help would be greatly appreciated. Thanks in advance.

 

i dont have any pics, but the sencor is on the passenger side, kind of hidden from the mass air sencor and the engine
on the bottone theres this big tube and youll see it sticking out
you can tell right away its the censor

 

Just wondering if there were pics to go along with the procedure. I'm kindda' handy with tools but pics can go a long way.

 

Hey Audiphobic

I need to do both of mine. If you put the front of the car on jack stands you'll see them in front of the secondary Cats. The trouble I found was getting the wire harness removed as it runs all the way to the firewall up front. Most of the harness is on top of the transmission so you cannot see what you are doing, all by feel. This was another reason, appart from being a third of the price, to get the Bosch universal replacements so I can just remove the old ones and cut them off without removing the whole harness. The replacement units are exact oe units and come with a splicing kit, so there is no soldering etc. In fact I've read you do NOT want to solder the O2 wiring as it can intefere with the signals.

I got mine at http://www.rockauto.com

Let me know if you are interested and I can get you the part numbers.

Cheers

I know this is an old post but could you give me the part numbers?
