Mitsubishi cars that have both MAF and MAP use it for EGR purposes mostly. Cars can be run on either MAF or MAP for load but in the cases of EGR Mitsubishi uses the diffrence of the MAF and MAP to calculate how much EGR is being injected in order to correct fuel more accurately.
My 2015 Mirage DE has a MAF, going by the pictures. You can tell there's a little rectangular thing stuck on the front of the air box tube, not the round hole, if you look at the under-the-hood view in my Garage picture gallery.
We bought the car recently in Illinois, USA, and assume it's original owner purchased it in the USA, too, maybe in this region, but possibly anywhere in the country, as it could have been a student at a nearby university.
This is my technical statement on the operation of a MAF sensor:
It works just fine.

I thought the US cars (that run MAF and MAP) don't have an EGR valve. Are there other reasons to run MAF and MAP as opposed to just a MAP?Quote:

Did we ever find out why the N. American cars, which don't have an EGR valve, use both a MAF and MAP?
Has anyone had any luck replacing either the map or maf sensors? I tried to order both from Mitsubishi parts direct and was emailed they discontinued the map sensor and there will be no replacement. I got a P0068 CEL
I've only had to replace one map sensor over the years. I have seen broken wires throw maf codes too.Quote:

I also somehow buggered up the pins on a maf one time, not sure how but one was bent over when I plugged it in throwing codes.
It was late when I was checking it over I will try again on my day off. I am using the manual to trouble shoot that particular Code that’s what lead me to trying to order the part.
I will start a post cause my problems are all over the place and I keep throwing money at it and I am sure I am missing something.
