Need help finding mass air flow sensor

Recommended Posts

2010 Ford E450 - Winnebago Access

We're getting P0171 & P0174 codes. Looks like one of the easy potential fixes is to clean the MAF, but all of my online searching isn't showing me where this thing is.

In the air intake line, between the air cleaner, and the metal of the intake manifold. Look for a small part, held on with a couple screws. It'll also have wires attached.

This shows how to clean it, but also shows location.

 

Thanks. I found that video, but it's a lot different layout from an E450. I found a video showing how to change the air filter and that led me to the MAF. WOOHOO!

Sorry about that, Candelmann. I remember that I typed in F-450 rather than E-450. Probably would have come up the same video like you said. Just glad you found it.

Once you've cleaned the MAF, it is time to start shopping for the replacement.  Cleaning will get you some time without errors, but not much
