Default Killed an o2 sensor? - 07-13-2018, 07:15 PM

Hello everyone, back again with another weird problem. I recently installed the ** fix and when I started it for the first time I checked both banks of o2 sensors and they were reading fine. So I took it on a test drive and within 5 miles she started running really rough and misfiring so I turned around and looked at my jb4 app and bank one was still reading fine but bank 2 was stuck at 20. I get home and remove the fix and reset adaptations and it's still stuck at 20 and running rough. When I clear the codes it smooths out momentarily and then gets rough again. I don't believe in coincidences did I mess up some simple wiring and killed an o2 sensor?

Another thing I'll add. I didn't have my secondary o2 sensors plugged in when I installed the fix because I thought I didn't need them.

Plug the secondary and reset adaptation and see if it fixes it. Sounds like you might have fried your O2 though

Sorry I forgot to update the thread. I bit the bullet and bought a bosch sensor from the parts store and it fixed it. Only replaced one because I'm planning on getting the adv o2's soon. She's happy again for now haha

I currently run the ADV O2s - pricey but seem to do the trick.

Hopeflly you donít burn up the OEM sensor, but if you do, ADV might be worth considering.
