Could this cause a car struggling to stay started on a cold start? I noticed after checking my MAS it was completely black in which i could not get rid of the Residue when spraying it. Once my car has started warming up the idle smooths out with no issues after through out driving the car. I have no check engine lights nor codes. I’m totally confused as to what the issue is. I also change the spark plugs.
+T. Farris We wouldn't be able to diagnose an issue like that here, you may want to have a local mechanic take a look at it. Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
I don’t have a check engine light on but I recently checked my cabin air filter and it was really dirty with leaves and debris… the next thing it effects is the MAS correct?
Sensor cleaner $13 or so Amazon... A new sensor for our truck $55- $145 at 1A Auto. ( The first large round type shown on the table) - Will start with the cleaner. Thanks for the thorough video. 1 A Auto is our go to place for parts for years.
My van (UK) went into limp mode when the MAF went. Main xdealer was £120 per hr plus parts, Local commercial garage £60 per hr, but they used original part. For the warranty.. now runs like a dream.
Hey your a good teacher but if you want to be an excellent teacher do this simple thing slow down. You masterfully understand these different things of how a car works but your viewer is not a master talk to people as if they are children slow down how you explain things and you will be the best teacher you could be.
I know this is an old video but i had same problem with my Silverado my engine light was on and off mostly on thanks for sharing this information and you nailed it with explaining
Awesome, I know NOTHING about cars but I'm learning so much from you, I love it. I will be doing the check-in on my car MAF and air filter. You make it all look so easy, I hope it will be as easy for me too. THANK YOU!!! You are lovely.
Len, thank you much for educational and clear presentation. I was be able to fix "check engine" light by cleaning MFA on my corrola from your video instruction.Thanks.
This guy is AMAZING simply AWESOME it's like he's driven my truck n know's feels n hears what my truck is doing HE'S MIND BLOWING THANK YOU TREMENDOUSLY SIR
Thanks for the video. My mother in law's 2011 Buick Enclave is having problems with the check engine light indicating Bank one problem which says it has rich fuel flow? Changed both upper and lower oxygen sensors, but MFS, also could be a problem. We'll check into it again. Thank you for the video.
Outstanding Vid. The explanation of the Mass Air Sensor and how it works and what it does, helped me to better understand the Air Intake system and how it effects Gas Milage. The Visual Inspection under the Hood of the Air Intake and associated system Components was also good. looking for loose parts and Leaks, that is Good stuff. Well done, Keep up the Good work.
Here's a little advice I just purchased one for my 89 Buick 3.3 . I spent the extra money and bought it off them A1 auto parts rather than buying a cheap one well guess what it didn't fit the guide pins where .003 bigger than the old one with no taper on the ends and one crooked so I had to drill the holes on the throttle body bigger . I left them good feedback on ebay before I had time to install it . Hopefully you get better parts from them than I did . Not sure if I will do business with them again . 🤔
You are absolutely amazing! Thank you for the great enthusiastic, upbeat, and thorough lesson. Was going to use vinegar in a spray bottle to clean the sensor. So happy I looked into this first. One question. Can't seem to find how to clean the fixed filter in a 2004 Lexus RX 330. Do I have to replace the whole filter housing? The inside is full of, what appears to be, nesting material. It is my mother's car and it only sat for 2 months, intact. We replaced all of the coil packs and spark plugs. Codes read 5th coil pack malfunction. When we were ready to replace the housing and new filter, we noticed the fixed filter on top. Then noticed the sensor definitely needed cleaning. And the inside is nasty.
Always enjoy your presentations. The ECU and details on how its works would be appreciated. Do they come from one or two manufacturers, then just programmed to the car company specs? What do you offer in terms of getting the live data out and examples of this. What do you think the 2020 and 2021 scanners models are going to evolve to?
Great job 1000000000℅ how can someone dislike passing on knowledge 🤦 either jealous greed like or cheap mechanics who rip's you off..keep doing the good work champ👍
I HATE NEW CARS! was a Ford mechanic in 90s, Mustangs, Fairlanes... we'd re build them up then maybe put 390s 428s... In them and maybe a MSD box, my 68 Cougar is 400+hp 289, no GD sensors. We knew, know how to adjust the carbs and timing... 2000 Taurus is my 1st fwd drive car ever had, 8 yrs, mechanicly fine I fixed it, all these BS sensors can blow me all the sudden with the trouble codes. I'll be getting my 82 Bronco 4spd going again, sooner than later! Good video though!
My smog test failed due to "too rich," then I went to Auto Zone and used a machine to test for possible causes and it suggested I replace the "mass air flow" sensor, which I did, and am now hoping the 'check engine' light stays off 🤞
Sadly the good explanation of how a MAF works is diminished by cleaning the wrong part of the MAF. What you cleaned is the air intake temp sensor bulb not the hot wire resistors. They are located deeper in the tube on that sensor and can cleaned as well.
Great instructor, this guy is the real deal. Not the problem I have but wow he is good. My 2013 Ford Explorer, stops on me while driving. I had a diagnostic tool plugged in which indicates code PO2111 ( throttle body stuck open) I have never done this before. How do I solve this problem, and how do I locate the throttle body actuator? Thanks for your help in advance.
super, super video, thanks. Question: in addition to cleaning the sensor probe, should you also hit the male/female sides of the connector with same spray?
Other instructions via You tube recommend spraying the inside of the Mass Air Flow Sensor with Mass Air Flow cleaner but you did not. Why? I am assuming you alluded to the reason why when you spoke about the internal circuit board.
Super, and well done,,, haven't bought many parts from you guys in 2021, but that's good since old folks are staying home more 😁 but best to all at 1-A1for the Holidays,, Bears Rod Shop, Tx
Great , explanation. I have a question for you. What should I do to to enhance MPG for Toyota Rav4 2001. I have replaced the four sensors on the cathalyc converter. I am getting 22.5 MPG on High way. Thank You, Mateos.
I replace my Mass air flow sensor twice on my 2012 Nissan Rouge in the past few months and my check engine light keeps coming with the same code. no leaks, changes air filter, reset the code and it drives great for a couple weeks, then when I'm coming up on a stop it will do a little chug like it wants to die and the check engine light is back on. any suggestions on what I should be checking for
hi brother. just a quick question, does changing the air flow sensor from a stock one maybe to a better branded air flow sensor could actually ehnace the air intake into the engine? does this modification actually affects the ecu or any parts of the car?
Hi.. Thanks for the video.. I have a touareg vw 2006 model has p0102 code and tcs light came on..thevair bag light also was flashing sometimes since long time..Replaced maf sensor.. It was fine for a half hour journey.. Tcs also went away..after hslf hour tcs light came on and scanned by odb2..code getting now p0101..totally confused.. Checked air filter snd hoses everything fine..intake manifold was removed once a time replace the head cover gasket.. It is fine fitted by looking..no leaks found anywhere.. I guess while code p0102 got i was got a misfire cilynder 1 and after multiple.. Do i removed out the spark plugs outvand checked one plug was little bent its metal rode where the spark occurs..removed out all plugs and coils..cleaned all with petrol and the bent plugs adjusted spark gap's and installed back andvsame time replaced maf sensor also.. After i am gettimg p0101 code.. Do uou have any idea about it..? It spatk plugs or coils damaged due to cleaning by petrol.? Is this bad coils or plugs cause this code..? I have a sudden or lazy pick ups sometimes while driving..gear shifting also not smooth sometimes.. But when clearing codes its runs fine for a hslf hour..after Tcs is on.. Air bag is also flashing some times....i am totally confused what to do.. Kind uour help please.. I am an Indian from Kuwait..
I had a hose the ripped off and it was extra long so I cut it in half and it still fit . It’s running good but now it’s saying my MAF sensor circuit bank 2 code . You think it’s because the hose ? I just cleaned the sensors but it threw the code up again

Just went to order a MAF Sensor for my 98 Mazda but you dont have any..
I don’t have a check engine light on but I recently checked my cabin air filter and it was really dirty with leaves and debris… the next thing it effects is the MAS correct?
Good Advice
If I had to take a class I'd definitely want you to be my instructor. You're information is so clear and understandable.
Sensor cleaner $13 or so Amazon... A new sensor for our truck $55- $145 at 1A Auto. ( The first large round type shown on the table) - Will start with the cleaner. Thanks for the thorough video. 1 A Auto is our go to place for parts for years.

This man is amazing at explaining. The hand gestures, close up shots, and overall detailed information. Subscribed!
You are beautiful 😍😍
Can do without the animated hand gestures, way too distracting. Awesome explanation though
He had. Me at "runnability"
You guys should be at a million views, all 3 of you guys are experts , simply the best I have ever seen.
You're so good at explaining.
Never even heard of MAF sensor. Very well explained and extremely helpful! Not my current issue but great job.
Come on
Nobody who just heard of a MAF calls it a MAF. Liar. :D
I know this is an old video but i had same problem with my Silverado my engine light was on and off mostly on thanks for sharing this information and you nailed it with explaining
Your simplicity makes a great deal. My lexus es330 does Engine hesitation,and I can see where the fault is coming from.
Awesome, I know NOTHING about cars but I'm learning so much from you, I love it. I will be doing the check-in on my car MAF and air filter. You make it all look so easy, I hope it will be as easy for me too. THANK YOU!!! You are lovely.

Enjoy this RUclips channel. I have a 2012 F-150 Lariat CrewCab 6.2L 4x4. When should I change the airflow, belts, hoses, shocks & struts?
I like it when the content creator know what they are talking about and give good advise to their viewers. 🍻
Such a clear explanation ...wow ..he should get million views....
Your very good at explaining, thanks for clearing up some things.
I loved this guy , I've seen a lot of RUclips videos but no one was as clear as this guy thanks !!!!

Now I'm going to watch some more of your videos.
You are absolutely amazing! Thank you for the great enthusiastic, upbeat, and thorough lesson. Was going to use vinegar in a spray bottle to clean the sensor. So happy I looked into this first.

What do you think the 2020 and 2021 scanners models are going to evolve to?
Thank goodness for this guy explained it 💯, will look forward for his next videos
I would agree, this guy's the best. Loving the (your), energy! Great stuff.

Thanks for the information....I just clean my MAFS using your method...
+Mahmoud Al Shawi Thanks for checking us out! 1AAuto.com
If you used method in video, you completely missed 2/3 of the sensor elements 😆.

+Jay Anderson Thanks for the tip! We'll pass this info along to our production team.
The way you explain this is awesome.
Very direct and to-the-point appreciate it all
Thank you. I just had to have my sensor replaced today and wanted to learn why (and what the heck it was lol!).
as an added bonus, you will see the check engine light iluminated, ha ha ...great vid. thanks.
Thanks you for giving me some information how to check mass air flow sensor
The hand gestures are killin me😆but very encouraging like a cheerleader 🤣Great job Sir🙏🏽👊🏽🤙🏽
I cleaned mine and all good!
Good afternoon sir I'm really appreciate your jobs please can you help me to found where the map sensor location please in the Toyota Noah 2007 please
Thank you for help .but I need to know about the idle air control valve where is it located
You guys are always there when I need you thank you
U make all this sound so simple to me
Thanks man.i know what's wrong now..im ordering parts now
Thank you. Love this presentation. Very helpful and educational.
GOOD. JOB. ..THANKS. I. AM TRYING TO. DECIDE. ABOUT. A. SCAN. TOOL...THEY ARE VERY USEFUL..I CAN'T AFFORD A VERY EXPENSIVE ONE

Thank you for your time to teaching, and thank you for the video
This is aunt a comment but it is a question. I have a 2010 Ford 5.4 L and it surges what would cause that.
Good job in explaining this part and how it works
Great instruction, Great video. Thank You !
Hello wear can I get the sensor please answer need one please
You're a good teacher
Well done video on a little known about component - thanks
+John Goard Thanks for checking us out! 1AAuto.com

Lenn: drops airflow sensor
Random voice: Quick! The quicker picker upper!
Excellent demonstration... thank you.
Thank you . This would be my first time
Does it have any thing to do with transmission
What is a Veericle? Lol Great vid
🤣🤣🤣🤣🤣🤣🤣
Dude his hand gestures are amazing, right on the point! I think he is sign languaging to the silent community.
Excellent tutorial! Thanks heaps mate!🧰⚙️🔧👍
Thank you dear...u such expert ...very informative TPS information...thank you again
great video and a great commentator
Does my replacement have to be original equipment?

I am having 420 coad I have changed exhaust manifold cattslack converter and still get coad.I am going to replace this cheap part shot on the dark.
Great video clear as always
why the RPM in my nissan murano 2007 stays at 3 RPM when's I am waiting at trafic light ?
I had a hose the ripped off and it was extra long so I cut it in half and it still fit . It’s running good but now it’s saying my MAF sensor circuit bank 2 code . You think it’s because the hose ? I just cleaned the sensors but it threw the code up again
Thanks for this tech. Info. Q.. Can we use DW40 for cleaning MAF sensor... Regards.
Great video Bill Burr
