Anyone Clean their MAF (mass air flow sensor)
 

Looking to clean my MAF, CRC makes a product for this now

Anyone done this yet? Is it easy to get to the MAF sensor? Any special reset procedure afterwards?

I use a similar product called "Electrical Contact Cleaner" and it works fine.

Word of caution tho: these sensors are very delicate and easily contaminated with dirt or grease, so be careful when handling, and completely air dry the unit when finished.

To access it, you only need to disconnect the electrical connection and then undo the 2 philips screws and slide the unit out.
Replacement can only go one way, but don't overtighten the screws. The housing is only plastic and will crack easily.

All that is is non-residual electrical contact cleaner with a MAF cleaner label. I don't know how much this will cost, but I'd just go to the nearest electronics store and pick up some regular non-residual contact cleaner. Then just let it air dry.

yea I have heard regular electrical cleaner will do it but I heard great things about the CRC product, figure since I have no electrical cleaners I will just pick this up

thanks so much for the instruction very much appreciated;)

I have pulled my MAF sensor (I hope thats what I pulled:p ) now Do I just spray the cleaner into the openings?:confused:

^^^dude thats not the MAF !!! Its the flux capacitor !!! You fcuked your G up !!!



















JUST PLAYING :p

ok so if that is the MAF.... do I just spray the cleaner into the openings?

Hmmm . . . Interesting. According to the label instructions, you spray it liberally on, in and around the MAF sensor and allow to dry completely before re-installing. I'll have to try this soon. Let us know how it works for you.

Oh, yes . . . That is the MAF sensor.

Just blast it away. In that third picture, that little wire is what meters the incoming air. When dirt, grime, and oil (from say a k&n filter) gets on it, it affects the accuracy of the reading and thus could cause loss in hp or smoothness. So just blast it away clean, and let it dry. It's just alcohol so it'll evaporate pretty quickly. 5-10 minutes I guess?

Awesome, thanks for all the help guys.. I will post back with results after a lil while of driving hopeing my mpg goes up and if it does the K&N is being replaced with stock filter.

Removeal of electrical connector
 

The electrical connector on my MAF resists removal. How is it removed? What is the technique to get it off those little locking tabs on the MAF?

Look at the connector carefully and you'll see a release on the side that needs to be pushed with a small blade screwdriver.

When I did mine, I concentrated on the exposed sensor (wire) for a couple seconds and then the inside of the housing for a short blast.
Air drying only takes a few seconds and you're good to go.
Don't forget the electrical connector when you're done.:)

Good grief . . . Now, I need to go out and find a Torx 20 security bit to remove the sensor unit fron the main housing assembly.
