Im work on 2018 N Versa with code PO101 I’m not sure what the maf. g/s should be at idle , my (snap on Modis edge) info Specifies 4-7 g/s at idle I have 1.8 g/s. @ idle and 5.7 g/s @ 2.500 rpm so my maf is bad y/n
Like Matt said, that number is good and snap on is way off there, and P0101 is not usually the sensor and is most commonly the air box not sealed good, vacuum leak, exhaust leak in the front, dirty throttle body
Also know that there might be a bulletin for these that requires a software update to the ECM, depending on ECM part number. That's the first thing that needs to be checked I guess.
I've found that Nissans follow that general rule where the g/s is about the same as engine displacement with loads off, warmed up, at idle.
