Okay, I tried this before and got no responses. I need to know where the sensors from my catilytic converter run from and to. My converter was cut off of my truck and I keep getting conflicting answers. The Jeep dealer says it takes 2 downstream and 2 upstream. The 4x4 parts store says it takes none downstream. I cannot find where they (if anywhere) are running. This is really frustrating because I've got no answers from any forum and don't know if this is faux pa or what?

 

I belive there 2 upstream (beside the motor) and 1 downstream (rear of cat). There should be wiring for all 3 O2s.

 

There is two up and two down. If you search google for location of o2 sensors on 01 cherokee sport I have found some photos and diagrams of the locations.

 

nks to you both. I work alot so I just got a chance to check back. I checked the Google search idea and found just what I was looking for. I think (if I remember right) I have the CA version engine with the twin converters up top by the Manifold. Plus one that the punks cut off. So if I'm lucky I wont hav e to replace any sensors or wiring harnesses. I'll find out tomorrow morning. I post some pics of what I find.
