maf cleaning

[Mattyboy1]

whats the best stuff to use for cleaning the maf. as my car is hesitating slightly so i unplugged the maf took it round the block and it seemed fine. when i plugged it back in its slightly hessitant again and the eml light came on. plugged it into the fault code reader and it said mass air flow low signal.
so want to take it off and give it a clean.

Sounds like its on it's way out I'd just replace it

i wouldn't bother buying electrical component cleaner, as james has said get it replaced i think dealerships do a trade in service for the genuine bosch ones i wouldnt recommend getting a cheap item as these don't usually last

I tried cleaning mine, first time I used carb cleaner and to be honest it did the trick. Sorted the issue I had at the time. (Power was a bit low)

Had the same thing again so tried cleaning it in the same way and it now appears to have **** itself.

If I were you I'd try cleaning it yourself first, nothing to lose really

came with that fault cuz you drove with it disconnected, then plugged it back in, thats why theres a fault... thinks theres a low signal fault..

 

[Mattyboy1]

How do I get it back to normal then. Surely once you plug it back in it should pick up the signal again.
It was hesitating before I unplugged it. That's why I unplugged it to see if it was any better. And it was.

what he/she is getting at is that it has logged the fault so the fault will need clearing even if a new maf was fitted.

he/she isnt doubting you need a new maf

Sorry of it came across funny wasn't intentional.
After I plugged the mag back in and drove it for a while the elm light came in so I plugged the fault code reader in and it came up that the mass air flow sensor was low signal so I cleared the fault but the eml light is still on with that fault code so guess I will try cleaning it first if no joy I will get a new one.

Thanks for all the replys

Got some alcohol cleaner do I just spray it to clean it or leave it to soak in it for an hour or so.

 

[LEE69]

Spray all around the sensor inside the maf, leave it to air dry as long as possible

 

[Mattyboy1]

Do I just spray it through the grilles or undo the two torx bolts and withdraw it from the housing.

 

[LEE69]

Take it from the housing pliers get the out they are security ones, can get a far better clean then
