Very informative, thank you.
Thanks for watching!
متشکرم از شما آقای محترم ❤
keep it up; it is a nice start
Yeah thanks
Good video; keep it up.
thanks
If you unplug the maf whole ifling and the enhine stalled. That means its functioning fine right, and if you unplug it and nothing happen thats means it a bad maf?
I heard this is correct
Thank you for the info
I changed it and it still doing the same thang and when I unhook it its still cranked up with the new one in
Its bs. It matters depends on car if it has 2 banks that method of checking wont work
gracias por compartir😊
thanks
Good video
Thanks
good video
thanks
When my MAF sensor went out the main symptoms were struggling to gain acceleration, engine light was blinking off and on, my fuel was being ate up VERY quickly.
Symptoms of a faulty MAF sensor include acceleration struggles, blinking engine light, and increased fuel consumption. Prompt diagnosis and replacement are recommended to restore engine performance and fuel efficiency.
EXACTLY what my car is doing
Just take it out every 6 months and clean it .
How should throttle valve positions for leon seat car diesel
Throttle valve positions in a Seat Leon diesel car are dynamically controlled by the engine control unit (ECU) to regulate air flow based on driving conditions for optimal performance and efficiency.
what happens if you leave it unplugged?
Would the engine management light show with all the 17 signs?
I am just puzzle about the engine light so good question though.
Absolutely not. The light would come on if certain parameters are met.
Yes
So i have golf 4 afn tdi 1.9 turbo 1998
Issues i have hard to start 1
Hesitation on Throtle press when i do overtake and Take off fast etc so i unplug MaF it Goes good But After i go 90 100km Looks like Stops getting More speed like limp mode i guess
After i put maf On It dooes a lot vibration when idling at stop When takes of cant go max rpm At all and it Smoke white smoke tooo much dude i go 1 gear 2 gear 3 gear at least 50 km it sucks
So plz tell me should i give fault only this maf bcz My Maf Is not Removable its all maf itself stick at Place
I suppose it could be that . When my car is cold everything is fine, car respond and pulls well, once its warmed up it becomes, hesitant, non responsive, lacking power and fuel consumption isnt great either,
Hi mate I literally have the same problem on my Astra j 2012 did u find out what is the problem cuz iv had loads people looking and can’t find the problem
Code readers are near worthless. Any number of different sensors cause the same problems.
What we need is a code reader that tells you what sensor is bad.
A reader that you can directly plug each individual sensor and see if it is good or bad.
A reader specifically for that car and year.
I have two Mercedes. I bought a specific code reader for that car $800 bucks. Still it was not helpful.
Dealers, who spend, many thousands of dollars, are the only ones who may be specific to an individual sensor.
I can measure ohms in comparison to one sensor to another, but that isn't fool proof either, when the sensor can't be tested under a voltage load.
Get a fixed , it tells you everything. The code, in plain English Whats wrong with the car. How much it would cost to fix it,and where to take it in your area. And if you want to sell it, it will tell you what carfax will give you for the car. Nice gadget. Try it.
@@bobsoto7632 ? I have two specific code readers for Mercedes.
But they don't tell you what parts to replace just the system fault.
Example. Misfire. But doesn't tell you specifically why there's a misfire.
So a person has to apply guesswork and trial and error.
The FIXED will tell you everything in plain English it will tell you the code what causes the code to go off and what sensor is bad. In my case. I had lean banks 1 and 2 not getting enough fuel in the combustion chamber. I looked on you tube to see what causes that error. It came up with not enough fuel check line filter. Check pressure on fuel pump. Vacuum leak or bad MAF sensor. I disconnected the MAF, and the truck stayed running. I CHANGED out the MAF and the light went off problem solved.now I can pass my emissions test.😊
9 times out of 10 they say I need a new gas cap 🙄
@@billloyd3220 that's the BS I went through.
Bu sensör egr valfine komut veriyor test ettim hava girince egr valfi kapanıyor daha güçlü hava giriyor eger bozuksa egr açık kalıyor ve sonuç karaduman bu parça orjinal olanla her 5 yılda 100.000 km de degişilmesi önerilir 😊
stupid question, would the check engine indicator light and vsc indicator lights go on if there was an issue with the mass air flow sensor.
So then what is a MAP sensor and how do you know if it's faulty?
I have a stalling in low gear, I cleand the MAF, clean the trottle body, still no change but this problem it occure only during summer time, the shops already check it they found no problem, no engine light. Maybe I have injectors problem not MAF.
I got a P0106 code on 22 Silverado 1500
I saw that code on a bad "MAP" sensor video.
Silverados are like tampons
Will this part cause your car to start and shut off within 5 to 10 seconds i cant even drive my car it will not stay started
Try looking into crankshaft position sensor....my Mercedes would run for 30 minutes then shut off..had to wait for it to cool down then would run again for a few minutes ...changed my cps and now it runs fine
Hi i got a code p219e on my honda accord sport 1.5l if i change coils and plugs will that solve my problem or do i got too change my injectors
Hi! The P219E code on your Honda Accord indicates a problem with the fuel trim in bank 2. This code is typically related to a lean condition, which could be caused by a variety of issues including faulty injectors, vacuum leaks, or even a faulty oxygen sensor.
While changing the coils and plugs could potentially improve engine performance and efficiency, it is unlikely to solve the underlying issue causing the P219E code. If you suspect that the injectors may be causing the problem, it would be best to have a qualified mechanic diagnose the issue further before replacing any parts. This will help ensure that you are addressing the root cause of the problem and not just throwing parts at the issue.
If your gonna keep the car for a long time it’s worth it to have the fuel injectors replaced. Well worth the money to fix and it will run a lot better!
But what makes the car to perform better in a colder rain days ?
Moist, cooler air is denser thus the engine takes in more oxygen per unit of air. Water also expands 1,700 x - ish the volume of water. More oxygen + bonus steam power + cleaning some carbon too. Fill up your gas tank in the morning when it's cooler and you (theoretically, probably immeasurably) get a little more gasoline for same reason. Density per volume.
Mi carro se encendió la luz de check y dio el código de MASS AIR FLOW SENSOR lo cambié y la luz sigue encendida cuánto tarda en apagarse la luz ? Si alguien sabe que se lo agradecería
This all fine and dandy, but check this out my friends, my 2001 Toyota tundra threw 2 codes, upper bank 02 and a transmission code, what! Trans code🤔, my brother in law said the torque converter is incorporated into the emissions system, Great, now what, so I googled and found a man in a lab coat that basically said, “ it all starts at the air filter and ends at the tail pipe, the issue is usually before the victim, so I inspect the air filter alls fine, next is the MAFS, it’s dirty, I clean it, two days later no more codes😜
Help ! Combustion not happening at the right time in cylinder 7 & 8 F150 1999
make sure the coil on top of cylinder is firing
Or spark plugs are good

Whats the difference in a MAF, AND A MAS SENSOR ?
Just depends who your talking to
The MAF (Mass Air Flow) sensor and the MAS (Mass Air Sensor) are both components of a vehicle's engine control system, but they serve slightly different functions.
The MAF sensor measures the amount of air entering the engine, which is used by the engine control unit to calculate the correct air-fuel mixture for combustion. This helps to ensure optimal engine performance and fuel efficiency.
On the other hand, the MAS sensor is responsible for measuring the mass of air entering the engine, as well as the temperature of the air. This information is also used by the engine control unit to adjust the air-fuel mixture and optimize engine performance.
@OneAuto23 would a bad MAS sensor make car engine run worse when at operating temperature as opposed to cold idling?

They are the same component.. some ppl call it mas/mass airflow sensor and someppl call it maf/mass air flow sensor.. the confusion comes by ppl separating the work "Airflow" to "Air Flow" hope this helps. Its the same exact component now there is a MAP sensor which stands for " Manifold Absolute Pressure" Sensor
Those sensors are the same they measure the air flow coming in an example 1.8 liter engine. Should be pulling 1.8 to 1.9 grams per second that is to overcome the parasitic loss of the motor then divide by the into each cylinder to produce right air fuel ratio for each cylinder
Is there a fault code for a bad MAF sensor?
yep
P0101
po307 & 308
Other alternatives for women cause we don't know nothing about unplugging that shit 🤦🤷
😂😂😂😂
I have all the symptoms mentioned above except for the check engine light, I clean my MAF sensor but still the same. Any advice 🙏🏽
While the car is running unplug MAF sensor , if the MAF sensor is working properly your engine should shut off when unplugging. If u unplug and engine is still running replace MAF sensor its faulty
@@joelm.4446 I found the problem it was my PCV valve 🫡
I replaced my MAF but still when unplugging MAF the car still running but is a new MAF😔😔😔😔
@kmmmap3877 try unplugging battery for 15 min and plug battery back on so computer can relearn.
2 symtoms the rest the same
As my auto mechanics teacher told me in 1977 all a n engine needs to run is fuel and fire. And that is true so we need to go back to carbs points and a coil and to hell with all this electronic garbage. If we get hit with an emp the whole world go to pot everything fries nothing works so to all the lil go green whimps cars don't hurt the environment it's the hot air coming out of your pie holes let up live our lives and stop all the impossible to fix electronic poop !
Fuel and fire but in the right order😅
lmaooo 17 GTFO bro might as well say ur gonna need a new engine if u need 17 symstoms for a maf trashh content
good video
thanks
