The second

step is to

unplug the

connector on

the MAF

sensor. It has

a clip that

holds it firmly

in place, so

you need to

push the clip

with your

finger to

release it. ( red

arrow)

Then just pull

the plug off.

The third step

is to unscrew

the two torx

security

screws. To do

that, you will

need a trox

screwdriver

T20. After the

screws are

out, gently

pull the

sensor out of

his casing.

After you

have done the

above, you

will have this

on your table.

The next step is the cleaning. For that you will need a 3 or 4 cotton sticks and some alcohol.

* Use clear alcohol or start spray – do not use any spray or liquid that is oily or greasy.

Get the cotton

sticks

mentioned

above and

flatten them.

So they look

like this.

*If you don’t

do that, they

will not fit in

the openings.

The places

that you need

to clean are

marked whit

red arrows.

Easier, you

need to clean

the 2 metal

plates and the

*resistor.

*not sure it’s

a resistor, but

clean it any

way.

Now that you know what to clean, you do it this way.

Put some

alcohol on the

cotton stick

and gently

rub on the

plates. After

you have

cleaned the

plates (and

you will

know if you

did, by seeing

that the clean

cotton stick

stays clear)

wipe the plate

with a dry

cotton stick

and leave the

sensor to dry

for 30

minutes.

* Do not over

wet the stick,

no liquid

should pour

from the sick

when you

press it whit

your fingers.

After the sensor was drying for 30 mins, you can take it and retur it in the casings.

And you are done.

Dont forget that the car has to relearn the cleaned MAF.
