Maf sensor bench test?
Has anyone any info for a bench test for the MAF sensor, like reistance checks etc......

They aren't that simple to check.

You could compare two at constant revs say at idle and 3k rpm via the volts out on pin 5 for the flow or the volts on pin 1 for the temperature volts out.
