    Ran across this article on how to test Ford MAF sensors, I was wondering if it is worthwhile or not:

    So based on this, is it OK to assume that it's also possible to monitor the MAF voltage output during the "snap test" with a common multimeter by simply backprobing the MAF signal wire? Has anyone done this test before?

    I don't think you can use a DVOM for the snap test because the readout is not quick enough. I am going to try that though, just so I can see what the voltages are.

    It should be possible, if your meter has a peak hold function. No, I haven't tried it yet. It should also be possible to test a MAF on a workbench. Use a shopvac for air flow, a powersupply, and check the manual to see what volts to hook up to which wires. That obviously won't be calibrated, but it would show if the MAF responded to air flow changes.
