MAF Sensor
1 - 17 of 17 Posts
Don't clean it! It will cost probably $250 for new one if you damage it...besides why would it get dirty before 1st change or after 100 changes unless you run lube/oil filter such as K & N and oil it too much. Looking at air filter cover from front, it is just left of top cover of air filter headed to round intake with a 1/4 screw holding it in place. Good luck and welcome to the world of CT owners! Ken

Yes be very careful handling it and don't drop it or touch the delicate sensor wire inside.
Be sure to get the right cleaner spray to do the job and a second or 2 squirt should do just fine. Allow to air dry before reinstalling.
Leek, I believe that there are 2 small hold-down screws and, hicksrt, be careful not to overtighten them. They have washers and need only a couple of pounds torque.
Enjoy the new ride.

You had me wondering how good mine was and my air filter needed a cleanup so I took a few pics of the sensor and its location and mounting.
Once you have the sensor in your hands, just a couple of quick squirts on the wires inside the housing is all that's needed, then shake out the excess and air dry for a few minutes. Needless to say don't drop it or you will have to buy an expensive replacement.
When removing the mounting screws, put a rag underneath to catch them should they fall. They're awkward and small.
2 mounting screws removed to expose the sensor. Wiring harness still plugged in:
harness now unplugged:
and the mounting location - on my K&N it's at the rear -- I think the OEM was too:
Sensor on its own, 2 screws, and hex key. OEM has 2 philips screws instead:
and finally the sensor housing on its side exposing the delicate wire sensors on the right of the body -- These are the wires that measure airflow and must not be tampered with, touched or dropped:
Let’s back up a bit (great pics CCT for sure…you missed your calling as photographer) and ask why we want to clean reference bead MAF?
This is no difference than a flammable gas monitor which I use on my job for a living…oil and gas industry. When an “oily” coat/mist/residue blows past the reference bead, from the clean side of the filter, it leaves a thin coat on bead and creates greater resistance sending a fault to our Honda computer. Dust/dirt does not adhere to bead due to filtration and non-stick particles from filter, but if we use a ‘oiled’ type filter we need to clean bead (after oiling every 50K miles) to keep oil base off MAF as it flows past it.
So why do we need to clean MAF unless we drive behind an asphalt truck or have a installed oil type air filter such as K & N?

how much will this be save interm of MPG with this kind of midification?
just hopping someone can step to the plate can answer this one
thanks

I got one on my Toyota Tacoma 03 and see no difference but maybe 1/2 mpg? Sounds great though…with a little more hp at top end.

Well not so much look but sound is great on my Toyota anyhow. And I do get better than 1.5 mpg when at speeds 80 and above but that could be negated by a speeding ticket?

You're probably correct, Leek, in that we don't really need to clean the MAF but I like tinkering and also have heard that it can get dirty from oils in the air, pollution from road grime, oils from filters and dirty filters, so why not? As long as one is careful, it won't do any damage and may even improve things and keep the engine ticking over famously and optimizing your gas mileage and carbon footprint.
As has been said, tho, 'tinkering' isn't for everyone, and could be expensive without proper care.
As far as photography: I like shooting the cam now having given up shooting guns long ago in favour of conservation. I find this far, far more rewarding.
Cheers,

I agree with ya. I do clean mine since I have K &N oiled filters but a novice sure could mess one up huh? I still am on guns though but...I still say you missed your "calling" regarding photos...what type camera do you shoot with?You're probably correct, Leek, in that we don't really need to clean the MAF but I like tinkering and also have heard that it can get dirty from oils in the air, pollution from road grime, oils from filters and dirty filters, so why not?

Yeah, got the K&N too so the MAF should be looked at occasionally to keep it good.
Cam? Nothing fancy, just a Canon Powershot Digi...Mostly for convenience and simplicity.-- seems to cover most of my needs especially uploading.
Got away from more involved photography when Digital came available some years ago but at one time my 35mm with various lenses was my toy for years.
Can't really justify a newer 35 digi but maybe someday again. Would like to develop my picture taking ability. Thanks for the kudos but it really is quite rusty.

I have a PS SD900 but not nearly the pics you take...I had to delete 6 out of 10 pics to post my K & N filter minder. No I Stab on mine.Yeah, got the K&N too so the MAF should be looked at occasionally to keep it good.

What are you cleaning? the 2006 5.7 Liter Dodge Charger RT does not have a MAF senosr, they are speed density based control system.
