DIY: MAF Sensor

[DjAtB]

Dear all Tai Kors,

I get to read this cleaning MAF sensor from few forums. I really wonder whether it works or not?....Btw, did anyone here tried DIY before? Please advise....I'm planning to do it but really scared me out..hehehe...

They mentioned the cleaning have to be done by using 99% pure isopropyl alcohol...But which particular brand that you guys know of?...

Thanks....

It is not that difficult really..but you will have to be very careful so that you do not damage the sensor (which is fragile). You can also use CRC Contact cleaner or a alcohol base cleaner. There is also a special MAF cleaner from CRC, you will need to find these from the DIY store like ACE. Please do not use any oil based cleaner as these will leave a film of oil on yr MAF sensor and this will collect dirt and will create a problem like erratic timing, high FC..etc.
I have clean mine with the CRC Contact cleaner b4 and have not had any problem so far.

Hey by the way, I have been seeing yr car around Taipan USJ area quite frequently the last few weeks....have u shifted..???

I have been doing this before with my bro's altezza.Before cleaning his car really bad.When engine not fully warm it jerks like mad,cannot rev past 4k rpm.Even after warmed up the engine feels like sluggish,jab the throttle from idle it bogs down then the rpm raise.I'm not impressed with the performance at all.Out to the shop,I bought KURE Electronic Cleaner,take the airflow out,i notice thick black dust covering the sensor element,just spray the cleaner directly to the element until it shines.The element is inside the hole.And clean the air temp sensor at the side as well.Put everything back together,reset ecu,start,idle is perfect.No more bog down,cold and warm operation as good as new,pickup greatly improved,it drives like an Altezza should.I really recommended this clean up.Just to share my experience,hope this helps.

I did cleaned the MAF sensor with CRC Contact Cleaner, of which i bought it from ACE. So far I did twice and so far so good no problem. Just take out the MAF sensor and spray into it until it is clean and shine. Dont touch anything inside, and it should be safe.

I know the MAF sensor is attached behind the airbox, but where is the air temp sensor?

 

[cuscostrutbrace]

The air temp sensor is attached to the MAF sensor,when u take out the MAF sensor,there's one sensor at its side (air temp) and another one inside the hole tunnel (MAF) .

You can actually try shopping around the outlets that ACE have in PJ...Ikano, Summit USJ, Mid Valley...etc.
You are bound to see one.... or you can go to Jalan Pasar and try at the Electronic Parts shops ... plenty of them there coz it is like the whole area is electronic parts wholesale area..hehehe.
