In this video we will look at 8 symptoms that will tell mass flow sensor is going bad. The mass airflow sensor is used to tell the ECU the amount of air admitted into the cylinder so that the proper amount of fuel will be injected. The mass air flow sensor is located usually immediately after the air filter. The symptoms of bad air flow sensor include the following:
1. Check engine lighting
2. Drop in Acceleration
3. Rough or Jerky Acceleration
4. Hard Starting Condition
5. Black Smoke From Exhaust Pipe
6. Rough Idle
7. Misfires
8. Changed Fuel Consumption

My mechanic said can’t find nothing wrong with car took it to the Nissan dealership and was told it’s gonna cost 10,000 to repair at least. Bought an air filter and cleaned MAF sensor fixed the problem. I’ve been dealing with crooks
$10,000 haha. Like George Costanza said, "Yeah, like I'm gonna take my car to a dealership."
Hi. 2004. Toyota matrix. ,for more then 3 year. Come. On and off , but the car drive good. Then. I buy 3 month. I buy new. Batteries.

I just got scammed by the Nissan Dealership
Oh my goodness. my engine was smoking so bad which I replaced thinking is bad. There after I've been struggling with jerking, weak acceleration, rough idling, high fuel consumption and every other thing you just explained. Thank God I stumble to this video you have saved me. God bless you. Just subscribed to your channel. Can't even thank you enough. I feel like crying too 😂😂
Thank you very much!!
Were you at least able to keep that old engine to be used as a boat anchor?
Will check mine on Sunday
I am experiencing all those problems you mentioned.
Thanks for the video.
Glad it helped! And I wish you good luck with the maintenance plan!
Thank you for sharing this I am experiencing all of these symptoms you give 100% accurate and the best information thanks so much it really helped me
Thanks for your information... Last 3"4 days my 2009 corolla had this same problems but mechanics did so many things like tb cleaning plugs and coil changed...at last they figure out maf not sensing properly... 👍👍then changed it 🤝
Sounds like they were backyard mechanics to me? A professional mechanic would have done a scan and gotten an error code pointing to a faulty sensor.
Thank you for sharing this informative video on the symptoms of a bad mass airflow sensor. It's helpful to know that a faulty sensor can cause issues like check engine lights, poor acceleration, and rough idling. The explanation of how the mass airflow sensor works and its location after the air filter was also interesting. This video will definitely help car owners identify potential issues with their vehicles and take necessary steps to fix them. Keep up the great work!😄
Thank you very much! That was a wonderful encouragement!
@The AbJ Garage My pleasure! Subscribed!
I learned that a MAF engine will idle low when the MASS sensor is bad, but a MAP engine will idle high when there is a problem with the MAP sensor.
super explanation, i think one of the best video on symtems of air flow senser, you did a super video with super and simp;e way of explanations, keep it up, waiting to hear from more from you,
Glad you liked it!
Thank you so much for this info. I think this is all I need to fix my car.
Glad to help
Well was it????
Love your video. I've been trying to solve my rough idle / starting issue for a while now and I can confirm I got some of the symptoms you mentioned.
I have these symptoms:
- Rough starting. (I have to pump the gas a bit, when starting the engine in the morning)
- I don't have the best fuel consumption
- a little bit of grey smoking from the exhaust
- Rough idle / stalling when the engine is at operation temp.
- Sometimes stalls after 1 min, if I do a cold start and just let it idle
Items cleaned:
- MAF
- Throttle body
- IACV valve (including new gasket)
Changed:
- Fuel filter
- Fuel pump
- Sparkplugs
- Coilpacks
- Engine ground wires
- Vacuum lines and intercooler couplers
- battery
- Altenator
I'm going to install a fuel pump hardwire kit and a new MAF.
I hope it works haha.
Buy a new car as well..
Did you fix your problem, did you check or replace the engine temperature sensor, that could cause all your symptoms.
Could be 02 sensor is caked with soot or bad
my map had to be replaced right after my ecm was. i was out of a car for a long while. i got fixed and changed plugs wirez and o2 sensors filters ect.. it runs great now. i use rubbing alcohol to clean mine.
Wonderful! Thank you for sharing!
I listen to his voice to fall asleep so relaxing 💤
Very attractive presentation
I have ever seen. Keep it up.
So nice of you
You do not clean a mass flow air sensor with brake spray cleaner there is a special cleaner for mass air flow sensors that you can purchase at the auto parts store Walmart but you never use brake cleaner to clean a mass air flow Center
You are absolutely right!
Lol 😂 😂 😂 let it to clean it, you destroy the thin heatfilm Sensor cause the Suppe is to aggressiv!!
Hey man, thanks for your video. I think you should put the link to the MAF cleaning video in the description
Thanks 🙏🏽🙏🏽🙏🏽🙏🏽🙏🏽
Thanks for the info.
Im getting P107 Error Code. Cleaned mass Sensor with CRC Mass Sensor Cleaner Twice. Error goes away after I rest engine light, but still comes back. Tells me bank 1 running to lean? So maybe its time I replace my mass airflow sensor? But I keep hearing from others that that p107 code can be a nightmare and so many other things.
Hi my car altima 2015 sometime while i am at the junction. When i press the gas pedal to move.. Its takes me 2 strokes and sundenly accelerates and start to move. Kindly guide please.
Hi i have code p0171 and i tried removing the clip from MAF and truck did in fact turn off. So my MAF sensor is fine? What else could it be???
Hi I replaced my MAF sensor, engine light came back on almost straight away. I removed the wiring harness on the sensor, engine carried on running, which I was told it shouldn't do that. Is this a wiring fault? As far as I know the new MAF is correct, could it also be the MAP sensor? Please help, I'm tearing my hair out, over this Grand Cherokee Summit, 2015 3.0 crd. Thank you in advance
In some models, if the MAF sensor is disconnected or malfunctioning, the ECU may enter a default mode or use pre-programmed values to estimate the air intake, but this can result in a compromised fuel-to-air ratio. In such cases, the engine may still run, but it will likely experience a decrease in power, reduced fuel efficiency, and potentially rough idling or stalling. Furthermore, the vehicle's onboard diagnostics system may detect the MAF sensor issue and illuminate the check engine light. Have you scanned the vehicle for trouble codes? If MAF problem codes were generated and replacing the MAF sensor wouldn't fix the issue, it could mean there is wiring problem. Scanning the engine might reveal other problems as well.
I’ve got 2006 Lexus rx400h….ran perfect with no check engine light. I plugged in obd2 reader and read code p0133 so I cleared it to see if it would come back…now getting super rough idle…codes P0300-p0306 are now on, misfires…would that be the maf is bad or be the issue?
Bad MAF sensor can cause engine misfire. Insufficient fuel delivery or an improper fuel-air mixture can cause misfires.
Thanks much
You're welcome!
Is it possible to clean a MAF that has a film and not a wire; no one never explains the differences and which ones can't be cleaned. You need to know what kind of MAF sensor the vehicle has before you can clean it. correct?
Could bad signals from MAF cause Temperature gauge to toggle? My 2011 Nissan Frontier was fine until recently cleaned my K&N air filter, then Check Engine Light came on. Happened once before after cleaning/ oiling K&N. So, its obvious that oil got in them Sensor.
Now my Check Engine on and may temperature gauge has been acting funny: temp toggles but goes back to normal.
I'm running the miles after CRC cleaning to clear Dash lights
Anyone experienced temp gauge toggling?
Oh yes , the oil you spray on a K&N will mess things up sure , get cleaner and clean the MAFS .
@@jasontimothywells9895 CRC to the rescue but not this time...K&N oil got the best of my MAF Sensor. Had to replace. Got rid of K&N filter...oil is sensor danger
@@supercraig2009 why’s there oil recommended anywhere near the MAF
Hi sir
Pls share me detail information
I have Toyota yaris 2001 model manual. i hv got some proble like when i push the clutch then idel run over ( high idel ) i changed TPS and also Idel sensor still the problem is happen
another problem when i use signal light on or turn on any light engine shaking so
What should i do ???
Love the Vid Bro Great Information on the MAF 💯 now i fill like a MAF Professional Tech 😂😂😂 U the Man Thanks Keepem Coming 👍🏽
I really appreciate that! Thank you very much!
Great information..my 2008 Infiniti G35 car it Lost power in acceleration..I pulled out on the highway an it wouldn't go..it's just lazy I would stop at the stop light, stop sign an the car just wouldn't move I ofto almost floor the gas pedal for it to go..an then I can hear a little vibration like the car it's just struggling..
You can just have the MAF cleaned, you don't have to get a new one.
Thanks !

I have ford ranger 2009 model its burning lot of patrol, black smoke in the tail pipe and my airflow sensor its its damage inside. Whats the course of black smoke
DO NOT USE carb cleaner or alcohol specially it dries things out.
USE ONLY M.A.F. sensor cleaner. or cleaners designed for sensors/electronics. they dry clean an leave no residue
Well said!! I totally Agree! Thank you very much!
Do you know if a 2016 Hyundai Tucson 2.0 have a MAF? I can’t visually see it. Would like to clean it.
Am not sure about your particular model but on those I saw it is immediately after the air cleaner housing, on some models you would have to remove the air cleaner housing to get to the MAF sensor!
I have a 2011 Chevy impala v6 LT check engine light is on reduced engine power both came on once I replaced my starter and traction showing up also but
It starts perfectly… I go into drive and my car moves but then it’s like the car isn’t responding to the wheels anymore not even in reverse I push the pedal and it’s nothing but I cut off the car and restart it it’s back working but it doesn’t last long I’ve changed the throttle body (this probably the shiniest part on the car now lmao ) and the acceleration pedal now but notice I was getting more response from the old pedal then the new one. What can be the issue it’s like a sequence with it having to restart it for it to only work but only for a couple seconds

Could this possibly affect other sensors? I got the P0068 code. Throttle position, MAF, MAP.
sometime its only dirt air cleaner thats why the intake cannot flow air normally thats it
yes indeed!
My car has no check engine light on but sometimes car moves very slowly when I accelerate, especially at traffic signal lights. Car don't move as expect. And very high fuel consumption. Would that be the problem of MAF.
Bro I have a same issue .. could you help me out… how did you fix it this issue
Can we use carb cleaner other than mass airflow sensor cleaner to clean massairflowsensor
Preferably use MAF cleaner always.
Waoo very detailed explanation.👍
Thank you so much 🙂
I have got Toyota spacio 4AFE engine when you load the gear it just cut but if you adjust idle to high idling it will not cut pliz what will be the problem I need help.....
If the idle speed is lower than recommended, many different problems could be a probable cause. dirty fuel injectors, clogged air filters, bad spark plugs, and ignition related problems are among them. Meanwhile if the normal idle setting is made lower than recommended, engine cannot handle the load on car start up. Some people intentionally reduce the idle speed setting to save fuel and the car will have difficulty starting to travel and have frequent stops.
I have an issue with an infiniti g35 that has a multiple cylinder misfire. This happens when the engine warms up but when it's cold there's no misfire. Sometimes it take a long crank hope someone can give me some insight.
I had a problem with my 2006 Chevrolet Trailblazer SS that would cause it to slam bang shift when it got warm and when pulling a light weight trailer. It ran just fine, didn't use more fuel than it normally did, and the check engine light NEVER came on! I replaced the MAF and the problem with the transmission shifting never came back. Just to be sure, I pulled the plug on my new MAF and the problem immediately came back. This was tough to find because the slam bang shifting only happened when pulling a trailer on the highway
Engine sensor location and its specification for 60 series engine
To find the MAF sensor on any car, just find the air cleaner and follow the duct that is going to the intake manifold. You will usually find the MAF sensor right after the air cleaner.
Really must there be 4 or 5 commercials in a video
Hello guys I changed new Maf but still have problem why??
There’re numerous reasons to these specific symptoms beside Maf sensor. There could be a leak in emissions vacuum, purge valve not working properly, canister gone bad, brake booster leaking air . The best thing to DIY, is to get a OBD reader and watch some good videos on RUclips which they show you how to monitor those symptoms using OBD reader in real time to pinpoint the problem. Don’t change anything until you know what is causing. I learned hard way by changing coil pack & spark plugs just to find out that the purge valve was bad & I had to change it. But I still have issues currently working on it myself to save some bucks
wat was the problem
I have a 2008 infinity G37 coupe where is the intake air temperature sensor at. ? Please answer ASAP
9 - DPF Regenerations would run much more often than what they should creating excessive heat ending up in a melted DPF or blown up turbo or both
Thank you very much!
Does it take time for light to go off once the MAF is changed ?
No you have to reset it, but it shouldn't come back on if you cleaned it properly. use ONLY Mass Air Flow cleaner CRC is usually the best. NEVER use carb cleaner or brake cleaner it can damage the sensor and leave residue behind which gives false readings to the ECU. Do not clean it when it it plugged into the car, remove it completely and disconnect from the harness. Allow it to dry for 15-30 minutes before plugging it back in. To Reset the light you can by a cheap OBDII scanner from Walmart or Amazon that costs around $20 Hope that helps. Autozone and Advance Auto reset them for free
On some models the check engine light will be turned ON after some time of starting the engine, and therefore once the MAF sensor is cleaned and replaced, the check engine will go OFF. On other models, you need to reset.
i clean the wires with isopropyl alcohol wipes. can spray first and spray screen. they can look different on various cars.
@@TheAbJGarage and other Modells habe a wide spectrum thats the Mil doesnt Set!! My own Car has some Problems between 1200 and 1700 RPMs with acceleration is hopping but i disconnected and drove without the MAF. And the Problem are the same!! 😉 😉
I just changed my plugs, coils, and MAF together..I'm having smell coming from under hood and exhaust. The light is still on...
Red Bank, NJ Blessed Love
It's very wonderful to have you here!
Thanks much but how do we clean it
I've watched a lot RUclips videos about Mass Air Flow but non have given me this full details Thanks
So nice of you!
Very informative, I believe mine is faulty
Sorry to hear that about your car! and am glad you found this video helpful.
Thank you so much for this very informative video. I’m getting the misfires. I already had the plugs changes and the coils checked. This will be my last ditch effort before taking car back to the shop. This is starting to sound like the solution. Either way, thank you so much for posting this!
You are welcome! And good luck!
Did this fix your issue?
Yes all true👍 very well spoken
Thats very good explanation of mas air flow sensor
Or you could read the fault code and not watch this
It may show more than one code
Awesome! Simple but detailed explanation of the MAS to the point even I cld understand & I know nothing about vehicles! Got my van running smoothly
Awesome, thank you! Glad you liked it!
Very Good!... #9 ✝ {9-25-2022}
Thank you very much!
Ive always heard to ONLY use MAF airflow sensor cleaner, nothing else.
Lol 😂 yeahhh thats the Best way to destroy the MAS....
You are 100% correct. NEVER use brake cleaner or ANYTHING ELSE. It will damage the sensor.
i use maf cleaner spray and i wipe the wires with alcohol pad gently,, leaves no residue.

Will ma's sinsore make my truck skip and run ruff
wrong MAF sensor leads to wrong air fuel ratio which in turn causes rough running
It's the one that came on it new
How do you change it?
It depends on the model! On some cars you need to remove hose clamps at both ends, on some cars the sensor is bolted to the air induction system and hence can be removed by removing the bolts!
use electric wire spray, it evap's.
I'm satisfied, thankyou verry much for the vedeo, watching from Papua New Guinea, 1 question, my crv Honda RD1 engine used to cut off when on the road while I'm slow down, what cause this please

Thank you very much!
perfect
Happy to hear that!
MAF Cleaner
👍
I just replaced my MAF less than a month ago. This should not be happening
There is two of them I just found out. One is directly after the air filter and slides into the side of the pipe. The other one bolts up in line, like this video
Thank u brother great video
My pleasure! So nice of you!
Awesome information & tutorial 👏 👌 👍🏿

What if there is no check engine light comes on
Thanks 🙏🏽🙏🏽🙏🏽🙏🏽🙏🏽
Any time!
How can i test air flow mass sensor??
You cant test this Sensor you need the table which mass on which RPM is possible but to get one is unpossible
Also if you unhook it and nothing changed then the sensors bad but if you do hear a change in the sound its working however may still need another one or cleaned.

You can use throttle body cleaner to clean your mass air flow sensor and throttle body,but u can't use throtttle body cleaner on your mass air flow sensor.
Noted
I have no power when I give my car gad
Gas
What sinsor should I check
I have a Vauxhall Astra diesel 1.7
2011 my dpf light came on so i took it for long drive on motorway the dpf light eventually went off 😊 but now my fuel is getting used up very fast
I purchased the forte injector cleaner and even that didn't sort the fuel issue out
How about the air cleaner? Check to see if it is getting clogged. Check your MAF sensor if covered in dirt, leaky injectors and faulty cold start injectors are also to be looked at.
@@TheAbJGarage all this you've mentioned is it related to dpf issues though?
@TheAbJGarage all this that you've mentioned "
air cleaner
Maf sensor
leakey injectors
And faulty cold start injectors
If all this is faulty above if I take it to my local mechanic tomorrow and if he puts it on computer will it all show up on computer all that you've mentioned?
@TheAbJGarage everything that you've mentioned if that is the fault then will it show up on the mechanics diagnostic computer??
