07 Rubicon 93k. Keeping in line with holiday season she just popped a P0038 code on me on the way to work today. Bank 1 sensor 2 heater circuit high. I had replaced the 2 upstream sensors about 8 months ago. Got in a bind and had to use Bosch sensors. Believe it or not I have had 0 issues with them. Said what the hell and grabbed one on my way home. Got her installed but no relief. Code is still there. Cannot erase that code at all. Didn’t notice any wire damage. Don’t know dick about electrical. Noticed on J-scan that sensor is running 1.27 at idle and not toggling. Took it on a drive and it drops voltage down around 58 and toggles somewhat. At idle she work back up to 1.27. So here I am! What do you guys think. Maybe need NGK sensor or something else? Any ideas or help greatly appreciated. Check engine lights just piss me off. 😂 thanks in advance
 
Kinda thinking that. Really surprised me that the 2 bosch upstream sensors work fine. Go figure lol. Do know anything about not being able to clear that code? JScan says you can’t clear a permanent code till it’s fixed and a couple drive cycles. Mine says (active warning requested). Weird. Maybe means the same thing

Not sure on clearing the codes.
