Hi Everybody-
I got a code P0138 "O2 sensor circuit high voltage bank 1 sensor 2" and a code P0037 "HO2S heater control circuit low bank 1 sensor 2". What parts do i need to order? Couldn't find anything definitive on the information super highway.
Thanks!

Do you have a FWD or AWD Juke? I don’t have the specific part number but what you might need is a knowledgeable mechanic who can troubleshoot your issue. Your issue might be just a bad sensor that’s shorted the 12V heater circuit to the signal wire, or you could have a wiring harness problem, or worst case an ECU problem, though the last one is unlikely. Anyway, before you start throwing parts at your car, do some proper diagnostics and it could save you both time and money. Welcome to the forums!

It's the second λ sensor,i changed it twice.Don't buy the original one,it will fail again,like it did with me.Get an aftemarket one, Denso or Bosch.

I agree with the above. BUT replace Both O2 sensors. Its an easy job and not too expensive. Take care installing them as they can be fragile.

The sensor on the turbo is prooved to be good,the second is the problematic one.

It's the AWD.
Thanks!

Not the case for the second gen Juke in North America. There was an issue with the first sensor that at minimum required I think a recalibration.
