NEVER Clean Another Mass Air Flow Sensor Until Watching This! 

I needed to do this. So I watched a bunch of videos about HOW to do it. I did it yesterday. It worked great. Now today, I’m STILL watching videos, about repairs, that I already did!!! Does anyone else do that??

EDIT :Just cleaned up the MAF and replaced air filter, cleaned the MAF housing too, the car now goes excellent, it's amazing, thanks Paul!

Scotty Kilmer twin brother 🤣🤣😂😂

My sisters Nissan Sentra dash light came on, in this case, I think it's called "service engine soon". So, she goes to one of the biggest names in auto repair and here is the bill, around 1,300 dollars. What's wrong? Well, the Mass Air Flow sensor code came up (100 dollars to throw the scanner on a car, when it's free at the auto parts store). Also noted, missing "clip" on air filter box, so, box won't close. The rest were minor things like air, oil, cabin filter and wipers. So, they tell her, 332 dollars for the Mass Air Flow Sensor AND 96.50 to install it. By the way, Nissan charges about 100 dollars LESS than that AND aftermarket ones are about 200 less. What's the solution to the missing clip? You got it, a NEW AIR CLEANER BOX!! 600 dollars plus 70 to install it. She is stunned and calls me, I see the estimate and say B/S. So, I take out the Mass Air Flow Sensor and clean it, it takes about 1 minute to remove it and put it back. Don't know where they get off charging 96 dollars for that install. I change the filters, and find nothing wrong with the air box. 6 dollars at Nissan and I have a new clip. 600 dollars saved (I would have found a aftermarket for much less). I reset the codes and fire up. I still got a code for the Mass Air Flow Sensor. So, is it ACTUALLY BAD? Do I NEED to buy a new one (but not the 332 dollar one)? I took another look and what did the shop miss (or worse yet, created)? A large tear in the hose that goes from air box to throttle body. Nissan wanted around 90, I decided to try a 18 dollar aftermarket, put it on, turned on car, and NO MORE ENGINE LIGHT. So, if that Sensor still has codes throwing, check for air leaks before you toss it. And find a more honest repair shop.

By far the best explained mechanic... My car will barely run its throwing codes p0171 P2015 P0016 P0299 this seems like the easier one to start with to diagnose that even I can do as a woman Thanks

I used Carb Spray Cleaner to clean my MAF. Helped as far as I can tell. I'll be on the look out for this specific product however and clean it again when I find it.

Keeping MAF Sensor Clean will Improve Gas Mileage and Better Engine Performance

Yes like he says, it dries almost instantly. You don’t have to wait 2 -3 hours like some other RU-vidr stated.

I thought you don't spray them upsidown cuz it could mess up the inside??

Thank you

You are the man :) Thank you.

Skatman John! Ski-bi-di-da-dop!!

🇿🇦 From South Africa: Please give the name or link to the site where to buy the MAF cleaner.Once again thank you for the post.

Great video, does he talk like this all the time😄

Red Foreman. Except he’s MUCH nicer!

yes sir thanks for the info

Well done and explained! Thanks for the video.

Can I use wd40 contact cleaner?

ty ... watched another vid and russian dude used Carburetor cleaner and a )Q-Tip !?!?!?!?!?!?!

Scotty is that you????? 😀

did you remove your battery connection? before you start?

Take it down a couple of notches... your at a 12🤏🏼 maybe a 6 or 8

Like a knockoff Scotty Kilmer

Excellent video 5 ***** The message was audible ,clear informative and precise and extremely helpful Thank you

Wear gloves, man, that liquid can't be good for your health.Try not to inhale the fumes either. Be safe, take care.

Who was first? This guy, or Scotty Kilmer? lol

Very detailed and perfect presentation Sir! My question is how often should I clean MAF Sensor? Maybe every time I do oil change? How many minutes should I wait for MAF Sensor dry? Hope you read this message! Thank you Sir!

Are you really supposed to inject cleaner inside the housing. I was always told properly just spray the sensors not inside the cartridge it short out the whole sensor unit. So note that the sensor is straight down never spray inside the cartridge of the sensor unit just the sensor on both sides not far not close but safe distance when spraying sensor always remember to keep the downside of the sensor down spraying the Sensor unit. Thanks Paul that was very instructional very educational.

You can also use electrical contact cleaner. Which completely evaporates.

This man does everything Scotty Kilmer does

wear some gloves! Solvents are not good for your skin.

can u explain a bit slower where the sensor is located? i didnt quite get it

I would add that the rubber o-ring be removed first, I experienced rubber warping with the MAF cleaner. Then clean inside first then outside wire. Lube the o ring a bit before reinstalling so it won't dry out.

I wonder how you wake your kids you with that tone hahaha, nice and helpful video sir

does this guy really talk like this?

I wish all how to videos were as concise and to the point and "flufless" as yours. I've got a question I hope you would be willing to answer. Just put on a new mass air flow sensor. Runs totally better except... *Engine slightly trembles in high gear going up a hill at lower RPMs. *While idling, the tach will pulse between 600 and 900 RPMs. (I drove this quite a while before I placed the sensor.) Could my plugs be fouled or does the computer take a day or two to recalculate everything. Or might I have some other sensors that need replacing? (2000 S-Type V-6) Thanks for any help you can give me, Neil

Your intensity shows me that you have a prophetic gift brother! Thanks and God Bless!

Why are you screaming?

Very informative video... you gave very clear, concise and excellent instructions!!

Hey.gd piece of advise dude..i have a 1989 sentra ex wagon...its a caburretor..that the engine has...and i dont kno where is the mass air flow sensor located...do you.know if this make/model.came with this..plz help

Hey, I used isopropyl alcohol which doesn't leave any residue and it worked just fine. It was really dirty too. With 111000mi I don't think it was ever cleaned. I've only had it for the last 18000mi.

What causes the engine to vibrate when the rpm is installed at 1500 rpm in a 2009 Sonata while parking, although I have checked it with the devices many times and I have not found a solution and sometimes it has double torque while driving.. Almost at a speed of 80 km

Straight to the point. Thanks!

i hava atoyota yaris but its not as easy to access the maf as easily as it is on your car there is too much stuff in the way but i will still attempt it at some point.

05 Pontiac Grand Am is acting up and symptoms seem to be related to MAF sensor. Going to clean it ASAP. Will report back. Thanks.

so why do you sound like the other youtuber scotty kilmer? is this just the youtuber mechanic voice or something?

Paul you are a treasure, and help so many people. Aunt Barbara adores you!

Thank you Paul! The content is useful but I love the delivery!

this is easy but somehow i stripped the screw and cant find other way to take it out except buying drill bit. any suggestion?? my last option is go to shop and have it taken out those screw out.

One of the better presentations about simple car component cleaning. Good job Paul! As much as I don't want to, I'll have to purchase either a ZEP brand mass air flow sensor cleaner or a CRC brand mass air flow sensor cleaner. Are there any less expensive MAF sensor cleaners available?

Thanks 👍 and have a blessed year...in Jesus mighty name amen

I think this is my problem on my 2006 Toyota corolla. Auto zone said it was my computer. Already bought a computer! SMH! @_@. Very helpful video. Thanks!

actualy if you clean any oil sludge in the engine vent side of the air cleaner that also makes the engine breathe better. btter to just clean the whole plastic assembly that goes from the air cleaner side and the throttle body side. remove the whole thing and wash it out as well as clean the MAF sensor.

Thanks Paul, I'm having issues like poor revving, lost of torque, hesitation, no power, very low gas mileage, can't reach over 3000rpm, etc. I already changed the filters, spark plugs and even that idle regulator which was expensive. Only thing left is MAF, so thanks on your video, gonna clean it like you suggested and than try it. It's a Ford Fiesta 1.3i Endura engine.

I like your profile pic, that’s why I clicked on the video.

Thank you 👍🎉 GOD bless you Paul🙏 Cheers.

You need to calm down and stop yelling at me 😥 I'm sensitive 😂

I have to remove my MAF anyway to clean the throttle body. It's nice to know how to clean the MAF properly, thank you.

Greetings from Aden/South Arabia, question to be raised do we have to disconnect the Bettery Negative Terminal prior of MAF Sensor cleaning ,many thanks nice and interesting information.

Rev Up Your Engines,,,

Thank you Paul. Another learned lesson in keeping my car up to date.

Great video. 👍👍 Is there an equivalent product to MAFSC? Can I use 90% alcohol instead as it's a quick drying solution?

Electrical contact cleaner will work fine too, but great tips on cleaning the mass air flow sensor. But still important message that Petrol, WD40 (except WD40 electrical contact cleaner) and any water based solution will NOT work! And very good tips on not touching the contacts directly! And great point that it needs to be done EVERY time the air filter is changed! Remember using wrong solution or touching directly can damage the sensor, so DON'T do it!

Although I appreciate the video, I will never understand why anyone would get solvents on their skin. There is absolutely no reason for this. Use a rag, or something to hold it instead of your hand. It's easy to research what these types of solvents can do the a human, (brake cleaner is particularly bad) or you can just not do it and not worry about it. These are known carcinogenics, dont do it.

This is a very good video, delivered clearly, with all the warnings that I humbly believe should be heeded. I'd never think of touching part of the sensors themselves. My father was the only person I've ever seen "mechanically" clean one. He used to take anew scalpul out and lightly run it up and down the wire with the touch of brain surgeon. for the rest of us mere mortals, we should stick to the spray, heh heh. God bless man!

I would add to keep the MAF upright at all times when spraying, the puddle on the floor will stain so down with some card. No need to go point blank with the spray, it's solvent. Extra care not to drop it, easily damaged through shock. Eye protection and gloves. If you have hands you can do this job.

If the spray dries very quickly, could you reinstall the MAF sensor right away and let the air flow finish the drying process?

I have almost an exact highlander just like yours, i have been working on it but no luck, changed throttle body, purge valve, spark plugs and fuel injectors, engine runs rough when I accelerate and makes a hissing sound at air filter housing. Please help!!

Outside the USA may be difficult to find MAF cleaner. But you can use good quality electric contact cleaner. Many report success. Of course, do at own risk.

I honestly really do think it does affect your fuel consumption my car start drinking gas bad i was thinking this is not right i knew something was going wrong but didnt know what a month later my check light came on mass air flow meter had stopped working i replaced it my car went straight back to its normal consumption i think it really does pay to service them .

Oow man! U crazy. I want to say in bangla, U R a Pagla.oow ya...haha....😆😆😆

Thanks, this was helpful, but has anyone suggested wearing gloves and eye protection? What is the solvent in the cleaner spray?

ah it just another scotty kilmer. video.......oh wait,its not

Just experience the same problem todae and my car is jetta 3Cli will have to try this thanks.

You sound crazy, like your trying to copy 'Scotty". I guess if it works tho lol.

Do not spray that MAF cleaner on any silicone gaskets especially the one in the electrical connector. It will make the seal swell.

Act and sound like Scotty

I nearly fainted when I done mine in shed😭😭

Thanks Scotty :)

Do I need to buy the oem or does aftermarket work for these.

What a stupid title for the video.

Hi scotty Kilmer 😁

Canal de repered, ils extensive,and IWant a shema intériorise of O2 sensor.good

Scotty says to fully dry a couple of hours.

I used normal dry contact cleaner and its work

You need the scotty sunglasses!

Lol ! Hilariously specific and to the point with no BS ! Thank you ! 😂

Thank you so much! It's a very clear video and even English is not my first language, it's still very easy to understand!

Don’t hold it in a way that the cleaner fluid goes into the actual sensor board though

Thank you, a nicely made video with great information. I needed this. God Bless you too! Amen.

So you don’t clean the connector piece itself? Just the sensor?

This guy's probably an elementary school teacher 😜🤣

straight to the point, no time for bullshit. thanks!

Rev up you engine. It’s time for ..........

Why are there any thumps downs, shame on y'all

Awesome videos thanks

Yes and for God's sake , don't use WD-40.

Why oh why the screaming? Jeeminy Jeebus man.

ECU reset once complete?

Your motor is just to damn clean the it's suspicious
