Hey all, 2014 JKUR here with 80k miles.

Trying to smog the car, but the O2 Sensor keeps coming back incomplete. Went to a stealership who flashed the PCM and told me to drive more miles , so i drove 350miles, still incomplete.

No codes, no CEL, everything else is fine, just the O2 sensor says incomplete.

Only mod I've got is an AFE CAI.

Anyone had similar issues?

I had that when I went to smog. I had cleared codes with my programmer.
They told me to drive about 50 miles and do as much at around 50 mph as possible. I did and it was fine.

Not sure what your problem is since you have drove plenty.

I could be wrong, but I believe that the amount of miles is irrelevant. It’s the number of successful closed loops operations that will allow all systems to start reporting to the ECU. I believe that the number is ten or so. A cheap scanner or cellphone app with adapter will tell you if your Jeep is emissions ready and save you the headache of trial and error.
