Hello,

Question. I ran the scan tool on my 2011 JK Rubi and it says bank 1 sensor 2 has no voltage. The other 3 sensors go up and down in voltage as I think they should. I looked up the part and tried to replace the 02 sensor in bank 1 sensor 2. The jeep is new to me. It looks like the previous owner cut two of the wires for that sensor and has them going up into the engine bay somewhere. There is some kind of round puck that the two wires go into and then they go up into the bay. Not sure where. The other two are still in the harness and plug in where they are suppose to. I removed the sensor and tried to screw in a new one. The new one will not screw in. Also the sensors look different. The one that is in it looks like it is just the center part of the new one.

Any ideas what is going on here?

Thanks in advance.

 

Answered my own question. Someone bypassed the cat so I changed out the O2 sensor and replaced the cat. All is good in the world.
