So many videos showing incorrect info about lambda sensors. This video is correct. Well done 👏

I've been dealing with O2 sensors for over 40 years now. This is a great refresher to get back to the basics. Don't ever skip the basics. Great video lesson.

Excellent i have been watching your you tube videos since you started makeing them i have been a mechanic 20 plus years and i allways learn something from you thanks again

Thank you so much!! Recently bought a new scanner and when I saw 2.XX volts on one of the oxygen sensors I thought it was defective or not compatible with a 2021 Odyssey since it worked as I was expecting on a 2002 Odyssey. Glad to now know a wide band range is between 0-5V! 💪💪✊

keeps getting better i work mostly on older cars and don't see a lot of the fuel air ratio sensors and have been struggling on my diag of them this made it so simple took camera and reorded this for refrence again thanks so much for the time and hard work

OUTSTANDING video!! Well explained. Thanks for posting!

As you say, I found this confusing, in part because of some variance between manufacturers as to how this is reported in the scan tool. I'm told also that the wideband sensors show more changes in current rather than voltage, with current changing to normalize voltage. Is it fair to say that all manufacturers follow a standardized pattern of reporting lambda low being rich, lambda high being lean? Mostly with these new sensors I've been looking to fuel trim to be sure I am getting the direction right.

WOW ! ! Already at 2:00 I learned something I was wondering about .

On a scan tool, Lambda may be recalculated by PCM as a nominal voltage outut .. but high V is lean, low is rich??? I think. (can someone clarify this point). Lambda may also be reported as a mA figure, again with high/increasing mA showing a lean condition, low/decreasing mA showing a rich condition?? That said, with everything there is an exception, and I believe that Honda's PIDs show high/increasing mA to show rich condition (like narrowband) and low/decreasing mA to show lean condition.
