    Its funny that I am going through problems with my 1992 Buick Century and it is dying at idle. Now no check engine light comes at all so I dont know if im going to get any feedback of codes. And its ironic that im searching for videos of M.A.F. problems and i just happen to see that this testing is done on the exact engine that my car has. but im very unsure of what my problem could be.

    if you even think your MAF is not working absolutly perfectly
    just replace it
    dont buy a 50$ retard detector to see if its bad

  6. ynnebbenny says:

    Where can I find information about how it actually works. As is what it happening electrically between the air movement and the sensor.
    To that guys who says, just replace it you even suspect its faulty, did you know they cost $180 AU each?

    What can happen to your engine if you dont upgrade your MAF and you modify the engine and it pegs the MAF

    Just up and replacing it may not be the best idea if you think it’s bad cause a lot of MAF’s are pretty expensive. A dirt cheap way to test a MAF is to unplug it and go drive your car/truck. If your problem goes away, you’re gonna be fairly safe in betting that the MAF is bad.

  10. dmorley100 says:

    Basically, it’s got an electric current that it pulses through a wire to heat it to a cretain temperature that it gets from the vehicle electrical system. The frequency they’re measuring is how often the MAF has to pulse this current to keep that wire at temperature X. There’s no actual electrical reaction b/t the air and the sensor, just how often it has to pulse current to keep a wire hot.

    What type of universal tester is it?

    This is not the best way and inaccurate way to check! Its not accurare except for the tabbing part. A meter is not as fast enough to be able to read signal. The best way to test is with a scope because you can see signals up to millisecond which a meter can’t and meter would not work on new model vehicles but a scope will.
