What is the best way to clean the air flow sensor?
I believe carburettor cleaner does the job, but how do you use it, do you just spray it on & let it dry, or do you flush it off with water?
I see in the US, CRC have a dedicated product for the purpose Site Link

Spray it on and let it dry.
You should see the brown gunge dissapear and a silver wire become visible.
Don't touch the hotwire element at all. They are very fragile, and if the wire breaks, its an expensive replacement.

just make sure it is carby cleaner you are using, not contact cleaner.
After using carby cleaner I then dry it off with some compressed air

Why no contact cleaner ? I thought either was OK to use.

I'd like to know why too as I heard that you should use contact cleaner and not to use carby cleaner. Never had a problem using contact cleaner on
mine, just takes a few sprays.

Hi,
I used Dick Smith contact cleaner on
mine and had to purchase a new one. It went from flat spots to not working instantly.
Mind you I did drown it

I have tried carby cleaner with no luck, so I just went and bought a new MAFS.
Expensive? Not really.
About $240.00 and considering drama with the car not running properly and the possible damage done to the engine, it's not a huge expense.

I went to my local Nissan dealer recently (Western
Sydney) to get a price for the MAF sensor (just for curiosity) and was quoted $980 !!!!.
So far no probs with
mine... Oct 2001 model

He quoted you that cos the cheaky plick included the ducting and pipework that it sits in as
well!!!
Go back and ask how much just for the MAFS itself.

I was the person with the original prado air flow sensor problem in this discussion. The car is fixed now. I used electronic contact cleaner and dosed it liberally. I had rung CRC direct and they told me to use CO Contact Cleaner. Dont use carby cleaner as it leaves a residue and maybe corrosive. The Mass Air Flow Sensor cleaner CRC make in the USA is not available in OZ. I will be cleaning the sensor in my car every 40,000 . Huge difference in performance.

Someone in the US compared the contents of the CRC MAF cleaner and the contact cleaner and they were the same they reckoned. Carby cleaner is pretty aggressive stuff.

Gday All
Local Nissan dealer and also ARB bloke recommended Brake Cleaner. They were both of the opinion that they are similar products, but the brake cleaner isn't as aggressive as the carby cleaner. I took their advice, and Brake cleaner worked a treat.......haven't done it for a while, might do it again next weekend. I was skeptical of the brake cleaner, but the nissan dealer would have got a visit if it didn't work or wricked it.
Cheers Andrew

Thanks for the replies, it sure looks like the jury is still out on the correct way to go about it, which was the reason for the post.

I clean a lot of things of this nature , but on aircraft .
We have gone from using various sprays to using Isopropyl Alcohol , cause it doesnt leave any residue .
The only problem is it doesnt dry very fast , you have to use compressed air or leave for a long time to air dry if the sensor is fragile .
