Doing good Doug! It's good to hear your Jeep is back on the road. I also had the O2 heater code showing up. My issues were with the sensor self testing functions. I was surprised at how long it took to clear. I was needing an emissions test and this had me worried. This might not be your problem but, just a thought.

OK I'm curious now because I have codes for all 4 sensors O2 sensor 1/1, 1/2, 2/1 and 2/2 Heather Circuit Low or High. There has to be something in common to give all 4 sensors faults????? Right???? I'm dumb founded on this one any help!!!!!

Were you able to clear your 4 O2 sensor codes? All four came up on mine and I have not seen any damage. Its odd to have all 4.

Thanks George
 
I kept having issues on my 2014 JK with O2 sensor codes. Tried replacing them and it didn’t fix it. Turned out my cats went bad. Luckily the dealer swapped them out under warranty. I was at about 75k miles when the lights started coming on.
