At what interval should one clean the MAF sensor?

Hi Jax.

I don't know what the service interval is for cleaning the MAF, but I cleaned mine earlier this year, and cleaned it on a previous car intermittently. It will take you about 10 minutes to do if you follow the guide below.
This has been covered in a previous post if you serach for MAP sensor.
Just be VERY CAREFUL with the fine wires inside the MAF sensor. They are delicate and easily damaged by poking them.


[quote="russben"]Righto. I have been out & cleaned mine.
1- pull up red clip on connector.
2- press center of electrical connector to release catch.
3- remove electrical connector.
4- unscrew 2x TORX screws holding MAF sensor to air intake tubing.
5- squirt solvent cleaner onto small electrical items & wires inside MAF sensor
6- allow to dry.
7- replace sensor.
8- replace screws, not too tight it's only into plastic.
9- replace electrical connector.
10- slide red catch down on connector.
Hey presto, instant 50bhp & 20mpg improvement! (not really, but the car does feel slightly livlier & smoother)

The third pic shows the small electrical 'gubbins' that you squirt the solvent cleaner onto.
DO NOT use WD40 or similar as dirt/dust will stick to it, and this defeats the object of cleaning it.

It took me 10 minutes including photo's. My car has 33k miles on it & the sensor did look a bit dirty inside before I cleaned it.

What type of solvent clean would you suggest?

I have aerosol IPA would that work? Former Mod/Member, with the most post & Chicken George Arch nemesis

I used an aerosol brake cleaner from the pound shop. That seemed to work ok and didn't damage anything. Poke it, Poke it, make it do it again!!
