It's weird, they are the same but they swap. That's what I'm thinking of doing before I take it to the shop. If I move Bank 1 Sensor 2 to the bank 2 side then I know it's the sensor. But would they actually fail in the sense that they are reading voltage similar to the Sensor 1? Worse case if...

Yeah I guess my mind just wants to know why or what's causing the bank 1 side to misbehave when the bank 2 side is almost textbook.

Yes the downstream on bank 1. Called the shop I used and he said his first thing would likely be to replace the cat. But I'm still thinking that would only be a band-aid since the jeep only had 75k miles on it.

Seems to be running fine. No lag or anything. Glancing through all the live data on scanner, everything else seems to be fine. Temp on both cats are almost identical as well.

And the Saga continues. Went out and ran some errands. No CEL but still had the permanent and pending code but the graph for Bank 1 was looking better. The Sensor 2 wasn't mirroring Sensor 1 nearly as much. Took long way everywhere with hills to really get the rpm's up. Thought maybe things...

Those are the ones I used, NTK

About to pull my hair, at least the little bit left!!! Maybe I'm overthinking but knowing the graph looks the way it does. Gas tank was about at 1/4 so topped off with high octane and added Seafoam to see if it would clean things up. Before I did that I check the scanner one last time and the...

That’s what I’m thinking. I’ll probably just give a couple days or two. The CEL is currently off, just my OCD killing me knowing the graph is bouncing when it shouldn’t.

Thanks again! That’s what I’m leaning towards. Guess I’m just having a hard time bc the bank 1 o2 downstream sensor is still bouncing like upstream. Even thought about swapping the O2 sensor to the bank 2 side to see if the problem is still on bank 1 or not. But those things aren’t easy to get...

Thanks! That's what I was thinking if I were to change out the cat it would only be a band-aid Going through your points: 1 - based on the scan above, it doesn't seem to be an AFR issue. No smell out exhaust. Not noticing a misfire but I need to check this again 2 - just changed oil, it was...

2015 JKU Rubicon - @75k Miles Could use some help on P0420 Code Had a P0052 02 Sensor 2/1 couple weeks ago and replaced all 4 O2 sensors, cleared all codes and ran good for about a week. Friday the CEL came on and scanner showed P0420 (Bank1). Seems to be running good otherwise. Checked for...
