Where is MAF

[ben beethe]

Where is the Mass Air Flow Sensor? I need to clean it since I am getting P0172 and P0175 codes and it is running rough. I have checked and the infamous elbow is not cracked.

on the intake... after the airbox, before the hose....

 

[Steve McKellop]

Don't use carb cleaner! Use cleaner specifically for the air intake or electronic parts cleaner! Spray it only. Don't go messin' with the sensor wire!

You can also put some on a Q-tip and then clean the wires. Better than spraying directly with the can

 

[Bill Barber]

Do Not touch the wires with ANYTHING, spray let dry, only with Elec contact cleaner.

 

[Kevin Palmer]

When you checked the hose, check to see it is not too weak and collapsing when vacuum is applied. Also, the crack normally happens on the bottom side.

I would not touch the wires at all. Buy contact cleaner safe for plastics. Or some parts stores have a maf cleaner. Spray the wires from both sides. Let it dry a few minutes.

Sorry, for some reason, was thinking IAC, not MAF.



On a side note, a Q-tip is great for cleaning out the IAC

Use CRC Electrical Cleaner that can be found in most parts stores. You will need a security torx driver (with the dimple on the end) to remove the two screws. I will reiterate Bill & Eddie said: DO NOT touch the 2 little wires inside the MAFS. If you do you run the risk of breaking them which means you will be replacing the MAFS to the tune of $350+.

I have an OEM maf for sale, when you destroy yours:banana:

 

[Matthew Runals]

when I cleaned it, I could not believe the difference it made. Truck ran so much better.

 

[ben beethe]

Thanks for the replies.

Do you know which size of torx bit it requires?

 

[Bill Barber]

T-20 saftey torx

 

[Woppy V]

i wouldn't unscree it either... they have a dye on the screws and if ever it goes bad and ford notices its been tampered with you get the full bill. 150 bucks or + i believe...

 

[Bill Barber]

You don't have to unscree it:lol: to clean it.

 

[ben beethe]

How do I clean the MAF sensor w/o unscrewing the torx 20 screws? Please provide step by step instructions as I am poor and don't want to screw it up and have to pay for a new one.



TIA

The sensor doesn't need to be removed from the housing in order to clean it.



Just disconnect the wiring connector, disconnect the MAF from the air box, and then disconnect it from the hose going to the TB. Then, spray the MAF cleaner on the sensor and let it sit for a bit to dry. Reassemble everything and you're done! Piece o'cake.:banana:
