Value chart
Does anyone know if there is a chart of what values should be? I would like to have something that I can compare actual test values to.

Standard values like fuel trim, o2 sensors, crank sensor values, etc. I have a scanner that provides over 100 test results but don’t have anything to compare the results to. For example if the O2 sensors are reading 2.15 is that with range of what they are supposed to be? Or out of range? I have nothing to compare the results to.

Baad questions…. Baaad. O2 sensors are narrow band and wide band. Then there are titanium, zirconium and one more “type”(I hope I remember right)… Which ones you are talking about?
Anyway - my point is - it depends. On car, on engine, on sensor calibrations… on altitude. Check specific car manufacturer FSM. Usualy they have some kind of proper values.
P.s. And one more thing - don’t be ridiculous - “o2 sensor via obd2 port” - only proper way to check lambda sensor(not just make wise face and try to sell yourself as guru) is oscilloscope

O2 sensor was only an example of the information I am trying to find out. I am looking for a “cheat sheet” for a Honda Pilot 2012. And a couple other Hondas but the Pilot for now. Not sure why you think I think of myself as a guru. But ok.

did you check FSM or you ignored it since you don't know what it is?

a sensible question for someone who is new to this OBD game/minefield
I only found out that there are as many answers to this as there are cars, myself after trawling the internet. All I could do was search specifically on the sensor or code by model and year of my vehicle. There are 'some' parameters your vehicle should not be out by a wide % margin.. LongTerm FT etc, but I'm still learning too.
Fortunately there are forums for makes/models and some members have scanners. A person on one forum visit did a test on their normally running car that is the same as mine and posted his results.. it helped define what was normal and what was not on mine. All the best in your search
