Re: MAF sensor diagnose
That is not normal. It should read 0 when the engine is not running.
I don't know the exact figures for your engine, but at tick over I would expect it to be somewhere around 6 or 7 and be steady, and rise to high double figures under extreme load.
Hopefully someone with the same engine as you can confirm the normal expected values.

Re: MAF sensor diagnose
These are the readings from a MAZDA 3 2L Petrol 2010
Ignition on Engine NOT running
And
Engine running ... Idling at about 750RPM
Try to clean your MAF Sensor with Sensor Cleaner first ...
