MAF (mass airflow sensor) cleanup day
 
3 Attachment(s)
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)

4. disconnect the wiring from the sensor.
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.

Make sure you disconnect the negative terminal on your battery before you begin. Don't want to accidentally short something. Plus, it will be long enough for the computer to reset and relearn your druving pattern with the cleaned MAF sensor.

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.

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? :-huh Thanks

wpnaes 02-12-2012 05:24 PM

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

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:

That sucks. Super glue should do the trick.
