for the past few months I've been getting P0138 and P0158 codes (O2 sensor circuit high voltage banks 1 & 2, sensor 2). not sure why since sensors were brand new bot long before that. I've checked the wiring and don't see any issues. Hard to believe I need new sensors already. any thoughts? Will it hurt to keep clearing the codes and just run as is?

Depends on where you bought the new sensors, "you get what you pay for" truer words were never spoken.

Probably didn't use NTK or Mopar. Seems like everyone automatically goes to Bosch and they don't work well for the KJ.

Did they really change the 02's ? That is the real question!
