A/F sensor (wide band O2) should have 1.5V, my scanner shows 0.3 B1 and 0.6V B2

 

Then you dont have a true wideband.
Those readings are from a zirconia showing slight rich .6 and lean .3 not uncommon.

Honda has a factory wideband that averages 2.7v
And Toyota the first oem to carry widebands averages 3.3v on stoichiometric

 

I replaced probably 20-30 O2 sensors, I know which one is wideband, I also have manufacturers manual. Wide band sensors 5-6 wires.
I have 04 Murano

 

yes some scan tools do receive raw values and reference them for another because "generic". what about a solus ? lol my favorite
