It could. I don't know of a way to really "test" one though. If you can monitor it, it measures are in volume (lbs//hr) and in speed (Hz). So if you're monitoring it, and you're play with the throttle and you see volume increase/decreasing as well as speed increasing/decreasing as you actuate the throttle, it tells me the MAF is working.

A good cleaning with some MAF cleaner (or other electronics cleaner) would never hurt it either. Just spray it. don't try to brush or wipe those thermistors in the vane section. They're fragile and will break, and THEN you have a MAF problem. :)
