    We are going to try something new in the next video! We are going to go over the thought process and detail of the two I have just posted , and we are doing it LIVE for Q&A . Keep your eyes posted for the date and time ⏲️

      Two? Looks like I need to look for the other one! TH-cam notifications suck. I'll have to check back here - I'll probably miss it live. 😬 I'll try not to, though!

    Awesome vid Keith!
    1) 👍 for stick shift ❤️
    2) why was heater duty stuck at 0% on the scanner?
    3) I have seen the same 4 codes on an identical Wrangler... But in that case the PCM was not able to supply power to the heaters, and the O2 signals were actually good but slow to warm up just by the exhaust gases. Also called a bad PCM 😁
    Couldn't you just do an NPR bypass sensor ground externally in your case?

      In all seriousness, I hope all is ok with the family.

    This was hilarious for me as about 2 hours ago, the 340 millivolts across the positive battery clamp of my Corolla, was masking a failed rear O2. The activity on the rear O2 didn't make ANY sense, and popped a P0420.(which is what got me looking) With the clamp connections cleaned, the sensor is now completely flat dead. LTFT is 21.9+ 600-2500rpm.

I've forgotten what that's like! I lived in Phoenix for 2 years over 20 years ago - man was that great! Kind of a double-edged sword though, because now I know how good I could have it, and am always thinking of moving. Wifey isn't onboard with that idea yet. 😔 Hopefully some day.

    Couldn't you just splice in the driver from the other bank-- and have your one good side run both sensors -- at least then it could fool the computer that it's working and keep everything happy? Not ideal I know.. and you lose your monitor function on that side, but could it work? (I live in Oklahoma and we don't have inspections, so rigging an 02 repair is not uncommon here. lol.. or just cutting it all off).
