LITERALLY THE BEST MASS AIRFLOW SENSOR VIDEO IVE SEEN BY FAR!!!!!! Thank you!
Have spent a lot of money on other senors and repair shop visits for my problem in a 2000 Miata. And after seeing this I purchased a mass airflow sensor and WOW, problem solved. Doesn't say a whole lot about the competence of mechanics in my area. This guy covered a lot in this video, but was all related to the sensor. Thank you for the video. It was well done. If ever in Midland Texas let me buy you a steak dinner and beer or two........................... Or three.. lol
Thank you for taking the time to make this video. My truck was running rough and rich. Cleaned the Maf sensor and it's like a new truck.
I know he knows what he’s talking about because I didn’t understand anything he said in this video
Funniest comment lol
Nathan Dominguez unplug the maf sensor and turn your car on if it doesn’t turn on it no work if it does turn on its ur beryllium agitator acting up causing non linear dioxide flow over the silicone filament of the pulse disruptor

CYPHER MOTE Oh jeez rick you know I really messed that one up man!
I've suspected a MAF problem on my new car (first time with a turbo and aftermarket intake), and this told me everything I needed to know. Thank you!
I have been struggling with a intermittent vibration at speed in a 2003 Camry V6 primarily going up hills. Symptoms were the car body and steering wheel vibrated. It felt like a out of balance tire (I just had the tires rotated) so I took it back into the tire shop and had the tires checked. I chased my tail trying to correlate the driving issues. Yesterday, the weather changed from sunny and warm (thin air) to cool overcast with light rain (thick air) and the vibration subsided! It had something to do with air density. I came across this video and you articulated how/why the MAF functions within the system. I was convinced this was the problem. I removed the sensor and cleaned , now Car runs perfect.
You very seldom get to see subject matter experts on UA-cam. Thanks for sharing your knowledge.
Thanks for your help. I appreciate your expertise and you taking the time to share it.
Liked the way he explained this. Even us girls could understand this. Great job.
Dude! You are a legend. Thank you for this spectacularrrrrrr explanation.
Wow! Your video has made me understand a lot better on how this all works. Very educational and have to say the best detailed and informative video on UA-cam. Thanks for sharing your knowledge 👍🏻
Nice walk through. If I were ignorant enough to not understand terminology... I'd look it up. You did an excellent job A-Z.
Thank you for a clean and clear video about the MAF system.
Thanks, nice descriptive explanation of a mass airflow
Sensor, you know your stuff. Thanks!
Love the video.... Just trying to get an idle of why my ford ranger is running rough...and I like the way you expanded things... Should have a show...
I wasn't expecting to get schooled by shawn, this guy is great! He protunes my car.
You just save me hundreds of dollars in repairs on my Jaguar with your explanation of how the MAF sensor works. I thought I had a vacuum leak that required a lot of labor to repair. I had installed a K&N filter on my S-Type and it started leaning out under heavy air flow. As long as the engine was cold and the choke was operating, no problem. But once the engine was warm, it would not rev over 3,000 rpm without the automatic ignition cutout coming on. The car drives fine as long as I kept it under 3,000rpm, which is about 73mph. Is that any way to drive a Jaguar? Hell, no!.
So I replaced the K&N oiled element with a dry element ($16) and installed a new MAF sensor ($14.74) and the check engine light is out and everything is fine.
very good information. you have described half the problems I have experienced before. Thanks Fastuun
Great presentation. I never post anything online, but I felt it pertinent to mention how well that information was delivered and presented. Thanks for that. Good stuff, Cheers.
I actually understood what you said. Great presentation, it was very informative.
nice!
lot of focused info in 10 min video.
Really gets a guy thinking .
Thanks for the knowledge!
Outstanding! Wish I (and the two mechanics who missed it) had seen this when my van was overheating. I thought it was running too lean and hot. They checked and replaced everything else - thermostat, pump, radiator, even the radiator cap without success. I suspect I probably over-oiled my air filter and or the MAF was just dirty.
Thanks You solved a car problem I had 20 years ago Great video !
Wow is all I can say. Amazing video! Thank you for taking the time!
Thanks. Have rough idle on cold start and I have to believe it is a vacuum leak by how you described the symptoms. Makes sense now.
Wow. I feel I should get a diploma or certificate in Mass Airflow! Great discussion on the topic!
That 'was' pretty in-depth & informative... I agree.....
Wanna really blow your mind?, and learn some deep shit about engines and how they work?, and 'why they don't' when they're having problems ?
Dude..?, .. go check out this Guy!! ... *He gives ya the REAL low down*!
To me, it was **!so interesting!**, I watched 'em TWICE !!
It's allot to take in, but Man, lemme tell ya ... It's fascinating! to learn how it all really works!!
AWESOME I tell ya !!!!!!
Enjoy ! ....... and .. learn. I absolutely did ! ! !

Good explanation pal. Thanks from the UK.
Makes a lot of sense now..had my k&n filter on there along time. Thanks
Thanks again bro, you saved me 130 bucks.
Great stuff! I almost feel like watching it again at half speed to catch all that information, lol
Why do people just take 12000 plus views and only 53 bother to like . Good solid and comprehensive info thanks

When I watch a knowledge filled video like this I always give a thumbs up , The creator put time and good effort in this vid !!
I been trying to get my truck to pass smog since 2017 and I been trying to figure out this lean code I been having for years ! A/F to lean bank one sensor 1 so I have changed both 02 sensors, didnt work , installed new cat converters still don’t work , changed MAF sensor still nothing ! But I do have a k&N intake and the MAF sensor is mounted underneath instead of facing up “. You just gave me so such valuable information That I been trying to find for years “ so last week I did clean another filter and sprayed some of that oil on and yesterday it’s giving me all kinds of idol problems “ codes popping up like crazy “ cylinders misfired ‘ just making my truck sound like crap “ so when you said it that the MAF can get coated because of the oil 💡. I hope it’s because of that I’m about to find out right now thank you so much
Well said & spoken. I understood the layout of symptoms better the way he explained it.
Very thorough information, loved the video!
This video is amazing! Good job in explaining everything!
Damn!!! U R smart as a Whip..very knowledgeable...Thank You!!!!
Good video and information; I really liked words toward the end of the video as how to test it.
This is a great explaination for a layman to understand what and how the MAF sensor works and what symptoms occur and where the problem might be...thanks
wow- that was impressive. You just gave me everything I needed to know
Daniel Martin agreed lol, he mentioned everything wrong with my maf lol xD
Best MAF sensor video I watched
Bravo! I didn't understand it all but thank you sir! Pretty sure my turbo Subie has a bad MAF. Will be replacing it on Monday :)
Very good useful information. Very interesting is the explanation and diagnose of various problems. Many thanks
This guy knows exactly what hes talking about!
excellent explanation! Thank you very much.
I have a 2012 wrx but im getting a exclusive fuel trim code running very rich .cleaned the maf and works great for a few days then it does it again . And no boost leaks. Started happening this summer the only thing different is that I've been keeping it in a air condition garage.
Great Video, Helped me alot... Thanks
Very good explanation...I would just suggest that you explain the jargon terms like "rich" and "lean".
dude, I learned so much from this video. gosh, thank you.
Physics and mathematics in context... Hot...! Thank you, I now realise I have misdiagnosed maf symptoms due to misunderstanding causes... make alot more sense now!
Thank you very much I was having problems with the rotary specs on my inline girder 😂😎
Great video, thank you. Very informative.
nice video good explanation really good info appreciated thanks!
thanks and i agree, you should have your own show. telling me how the MAF acts, or not, tied into another issue i have.
Dude .. Go check out this Guy !! and you'll understand a WHHOOLLLE lot more ! .. I certainly did !!
Absorb.. & Enjoy !! Lol
I take my hat off, great video man, Thanks alot

good information, helpful
Information presented on a nice rhythm and concise.
Great information!
Excellent explanation
Thanks ...very informative
Well explained
Thank you
Best explainer!
No idea what you said bro, the comments were the biggest help!!!!

Great video...thank you!
Very informative.
So yesterday my 1998 740il popped a p0301 and a p0300 right before my wife and I were about to go out of town and it was shaking bad and barely would accelerate. We ended up taking our van instead. I went and bought a coil for cylinder number #1, installed it and the car did the same thing. I took out all the coils from that bank and the spark plugs as well. They all looked good. I re-installed the plugs and coils leaving the new one out, disconnected the battery and touched the + and - togther, reconnected the battery and the car ran like normal with the slight miss it's had for the past 2 months. I pulled the MAF connector off and the car cleared up perfectly. I put it back on and the miss and slight shake came back. I was about to unplug it again and the car shut off when I touched the wires to the plug connector. Apparently the wires are frayed or something inside or at the plug. They're connected good enough that the car won't throw a CEL for it when it's connected but the mpg's are bad with it connected. I drove a round with it unplugged for about 4 miles and my mpg's are at factory spec, sometimes better like up to 20 mph in the city. When I shut my car off the CEL was back on with the codes P0100 P0130 and P0136. I understand the P0100 but any suggestions would be great. Thanks
I was wondering why my 1990 Olds 98 3800 is getting poor (20.1 mpg) gas mileage and I noticed the 1 wire was black with soot or carbon. I hope this helps. Thanks for the video.
Good information thank you.
Good solid advice
You'd make a great professor. I know nothing about cars and ten minutes later, I'm part pro.
Great video! Thanks!!
helpful, my car has that problem ( audi a4 b8) I will have it cleaned abd see if the problem persist thanks.
Really good video lot of technical info, by understanding how a particular system works, it makes it easier to do a proper troubleshooting. Thank you so much. We need to support channels like this because that is what we need when we are trying to fix our cars.
I have a 16 wrx with a Cobb intake and I’m having negative AF learning 1 badly at like -20 to -30 and this only happens at idle and low throttle; it’s only a problem that has recently happened but the intake has been in for over a year. Where should I start to look first? Cleaning the maf or checking for a leak? And does this sound like a vacuum leak or a boost leak? I might have missed it in the video but I didn’t quite find what my problem is in the video
Very good vid!
Thank you. Gr8 video.
Ijust put a brand new maf sensor on my 02 325i BMW, and even if I unplug the maf sensor the car would stay idling as normal. In yr opinion what can cause this problem. Thank you.
very good MAF primer for tuners
THANK YOU!!!!!!!!!!!!!!!!
Last tip was a good lookout very close to home condition with my 325ci convertible 02. Gonna test and try cleaning maf and replacing my filter checking my O ring on my Disa and replacing my boots . Just got this car with only 77k miles but it sat obviously forever the engine is filthy below the covers . Was gonna go get familiar with the spark plugs after this anymore key tips ?
BRING BACK the Carburetors! Good explanation.
What is symtomp of rough idle after car has been driving more than 1 hour and only more than 1 hour? At the beginning it was smooth. Thank you
Wow you know your stuff ! 👍
thanks a lot , very good explanation theoretical, needs more practical on what you said the parts.. more zooming cam on the parts inside the engine thanks on all of it at the last I have to ask ::: ? what about the mass air flow controller if the conductive graphite has been removed or crushed or seems to be not conduct easy ?? is pencil graphite do any things better ? what to do please ?? azaad
Don't EVER touch that .. that .. thing inside the MAF sensor.. It's sensitive As Hell !!! Only spray MAF Cleaner on, and around it !! NEVER Touch It ..! and No Foreign Materials! on it either ! !
I loved this! I have been going blind and deaf reading stuff. I don't know crap about cars. You talk fast but, hey, You Tube has rewind. Thank you.
Your explanation on the function and the importance of the MAF being clean was outstanding, thank you...
Thank you smart dude
I have a question? Would a dirty Mass Air Flow Sensor if dirty. Could it be a cause of a vehicle overheating in idol?
My allion 1zz 2003
is stalling at 110km/hr.It does not exceed that speed,any help
if your getting por gas millage.two simple things to check is 1check for corect tire presure.2 check for dirty air cleaner.change if dirty
