Mass Air Flow Sensor Hums

Good afternoon,

I have a 2000 Explorer and my Mass Air Flow Sensor is making a humming sound. I can disconnect it from the air intake hose and the sound stops and then I can reconnect it and the noise starts again. Have replaced the sensor and the noise went away for a couple of hours but returned again.

Any ideas??????

Thanks in advance,

Charlie

Is the sound an electrical sound, or is it due to air passing through it? Does the sound change with engine speed? What happens to the sound if you just unplug the electrical connector from the MAF sensor? Of course unplugging (and removing) the MAF will likely set codes, but at least you'll know why they are there.

i had this same problem with my 2000 explorer it was the iac sensor it cost me like 50 bucks from auto zone and took like 5 minutes to change i hope this helps

Thank you mab6680 and shorod for the input, we will be checking things out this weekend and will report back.

Thanks again,

Charlie
