1995 Ford F-150 MAF

First off. Very few pre 1997 fords have a mass air flow sensor. But if you have one it will be in the air intake hose. Youll see electrical wiring going into the hoses. Thats the maf sensor.

If not your vehicle uses a MAP, manifold absolute pressure sensor instead.

That is locatged up against the firewall passanger side. Has a vaccum hose going to it.
