MAF SENSOR CLEANING GUIDE

Postby Shane M » Fri May 29, 2009 5:07 pm

A dirty MAF sensor can cause performance problems, the most common seems to be the dreaded flat spot around 5000 revs....

So this guide is to show you the steps involved in cleaning the MAF sensor...

Things you'll need
10mm socket
Philips screwdriver
Electrical contact cleaner

Make sure you do this with the ignition off !

First remove the 10mm bolt on the front right side of the intake and pull that section of the intake out, then you can see where the MAF sensor is located (shown with red arrow on pic)....... Now make sure the philips screwdriver you have is a good fit into the screw because these screws round off very easily and are also in quite tight ! ( if you can't unscrew the screws then it's a good idea to remove the whole induction unit as you will have a much better angle to get at the screws )

Now push the screwdriver hard onto the screw and turn anti clockwise and take both screws out, now you can remove the MAF sensor from the intake, just twist it to the left a bit and it just pulls out...... Now you can disconnect it from the power socket.... Make sure that you don't lose the rubber seal that is on the MAF sensor unit, it's quite loose for some reason :roll: (highlighted with red arrow in pic)

Now get your contact cleaner and give the outside temperature probe a good clean, also down the tube there's 2 more sensor wires like resistors, give them a good few squirts until they look like metal again rather than oily :) shake off any excess cleaner and the rest will evaporate...

Now plug it back into the power socket and install it back into the induction box and reassemble the intake and bolt her up.....Hopefully now there's no more flat spot and a lot smoother ride :mrgreen:

I bought my MAF sensor cleaner from here and it was about €10 shipped, but i believe any electrical contact cleaner will do.

Hope this helps :)
