It should be an apparent device. Normally near the air filter box. When you take it free from the air inlet hose it has its own housing and a wire in a shroud that runs across the span/diameter. It measures air flow by running electricity through the tiny wire to warm it up then measures the rate of amps to calculate how much air is passing by how many amps it takes to heat the wire...somehow the more air that is flowing the more power it uses and reports that to the computer as one of the inputs it needs to adjust the fuel mixture. And that is the entire extent of what I know about it. I had a computer code fault one time and it indicated the MAF so I got a can of cleaner and hosed it off reset the fault and the check engine light stayed off.

>-Are you sure your truck has one? Not many 5.8L's did. If so the sensor will be right on the airbox lid. It will have a single outlet that Y's into two going to the throttle body. If you have twin hoses going into the air box, you do not have a MAF sensor.
