I had a CEL and autozone said it was o2 sensor bank 2. My car is an 02 and only has the two front o2's in the header collectors. I pulled the passenger side o2 and it has about 16" of wire. The new one at autozone, Bosch 13444, has a shorter wire. Is this normal or is it a problem? Do I need the longer 13111?

 

So you have an ORY and no rear O2s? Did you have them edited out in the PCM? If you are going to replace an O2 I would recommend going with AC Delco.

 

Yes no cats the rears are tuned out. Which Delco one do I need? pn

 

Left should be 19178928, right is 19178921. I think they have different part #s because of different length harnesses.

 

So for my passenger side if I used Bosch do I need 13444 or 13111? Thats kinda what Im looking for, the length between the two. I have longtubes and just dont want to order short ones.
