MAF (mass airflow sensor) cleanup day

In between sneaking peeks at the Daytona race today, I'm cleaning the MAF. In case you haven't done this, here's a quick pictoral.
1. pop off the air filter housing
2. oops, pull out the key, disconnect the battery
3. pop off the MAF assembly from the filter housing with a screw driver (gently)

5. place it on a workspace and get out the spray.
6. Spray sensor thoroughly.

7. Let it all dry well before reinstalling.
8. If you run an oily airfilter, clean it up while you're in there.
9. Don't over oil or you'll be doing this again soon.

Thanks John!

in past 2 vehicles i damaged 2 of those mass air sensors from using k&n oil type filters. between the cost of the k&n, new air sensors, and oil cleaning kit, I would never recoupe the money spent in trying to save 1or2 mpg. just by the cheapest air filter every year and you'll be better off.

and to those who insist on using the oil... just keep your old cheap filter to use for a day or 2 while your filter soaks up the oil. trick is very little oil and let it sit at least a day or 2. if you try to spray it all up to make it look red your gonna wind up with problems.

Thanks wpnaes! The pics made the job really easy. Had some dirt built up on there and now have as smoother idle. Truck just sounds happier.

Question

Thanks for the post on this issue. I purchased my X with the K&N filter on it. I am going to clean it today and hopefully not over oil the darn thing. Should I clean the MAF sensor on a regular basis? Thanks

I clean it once a year. I clean the K&N every 6 months or so.

Thanks Stewart.

JWA encountered this issue while cleaning, I thought it might come in handy for others: (Thx JWA!)

I also did this but encountered a minor problem with the pressed-in threaded inserts that hold the sensor in the intake tube. Photos here:

If these would be useful to include in your post and/or tech folder please feel free to use them. This might not be a common thing but might be helpful to know in advance it can happen.

That sucks. Super glue should do the trick.

Can someone tell me where the MAF sensor is on my 02 Excursion with a k&n cold air kit on it? I don't see anything resembling the picture in mine...
