your way of explaining things is wow!!! thank you!!!
Thank you for showing how to fix this problem, it was simple and fixed the problem.
Thank you for this video! I changed the sensor following your instructions and everything is good now!!
bri her what year do u have
You made it look so easy. My daughter's 2013 Altima Has the same Mass Air Flow code. The sealership wants 300 for the part and then labor cost. Im going to probably get a better aftermarket part and install myself for her. Thank you for the informative video..
Thank you for this vid. I'm about to go get the cleaner and try cleaning first. My 2015 nissan Altima has 321326 miles on it and this is the first time this code came up. I will follow up after with my results.
321k miles on the car. That is impressive. Did you do any transmission flushes along the way?
You do a great job at explaining, oh, and I especially loved the cardinal flying in to check on you, lol, thanks again!
i know it is kinda randomly asking but does anybody know a good place to stream newly released movies online ?
@Aiden Duke flixportal
@Darwin Adriel Thanks, I went there and it seems to work :) I really appreciate it!
@Aiden Duke Glad I could help xD
Thank you! Clear and concise
Good information. Thanks for cautioning against brake & carb cleaner. Nice cardinal!
it is an amazing explanation, but that cardinal bird stole your show. you are so lucky guy
Replaced on a Toyota Yaris years ago and did the trick 😊
Thank you for making and sharing this video, it was very helpful!👊🏽👍🏽
Short video and to the point. Thank you 🙏🏻
Great job brother thank you!
Great video and cute cardinal! Nice little bird break 😂
love the bird part :)
Very good video!!
Awesome video. I'll subscribe. You'd be a great teacher of real history or knowledge and or a great father is bet. Cleaned my air filter and it was nasty. My mpg went up insane in a test run around block. I'll clean my mass flow this week. Thanks,great video. Hopefully your cvt didn't die. Notorious for these cars. I only have 37,222 miles but they go out earlier then that.
Mine went at 56,000 cost me $4700.00 to fix. I'll never buy another Nissan product. They are junk.
9:53 is my favorite part :)
Thanks for the video
Thank you you saved me a bunch of money 👍
Thanks for the tip
hi i got this code recently only difference my car went thru was me cleaning my knn filter and re oiled... about 1-2 mont ago do you think i used too much knn oil on filter? thus causing this code ?
Thank you so much, this worked perfectly for 15 Altima P015a 02 sensor issue. Pro tip, if you dont have a scanner, Autozone and most other auto part stores will scan your vehicle for free and give you the print out
Hey before you replaced the o2 sensor in your altima would it shut right off soon as you cranked the car?
@@cedricmiller4370 no sir, I only had the engine light on, no noticeable performance issues
@@cedricmiller4370 why I had the same issue so I crank my vehicle is shuts off now making a weird noise
@@mikegold4559 Describe the noise.. I have had a 2009-2019 nissan altimas except the '13 and the shut off after you crank can be associated with your sensors going bad. Do not replace any parts until you get your codes. If your codes show sensor malfunctions, try not to drive more than a few weeks before getting them cleaned or replaced. Driving with dirty or bad sensors can cause your engine more harm the longer it goes unfixed. Most altima codes for sensors happen right around 60k-90k miles (depending on frequency of use). Also, Altimas are one of the easiest cars to replace parts for. I taught my mom how to fix her own car, she has replaced headlight assemblies, belts, her A/C Condenser, mass airflow sensor, spark plugs, wheel bearings, rotors, brakes.. my mom is 68, if she can do it, you can too. CZcams has all sorts of DIY vids, you'll save tons! Good luck!
2013 Nissan Altima SV. Same code, cleaned the MAF light came back on. Replaced the MAF, light came back on. Searched online for more solutions, and folks have said a faulty PCV valve can give you the same code, or a dirty throttle body. Checked the throttle body, and it's clean. Next is replacing PCV valve and hoses.
There was a service bulletin on the pcv valve, the cars came with some fault ones and Nissan changed the model to the black color valve I believe.
So what did you do to make it work…changed all those items but still have my light coming back on. Believe I need to get the Ecm reprogrammed
@coachtrollinger that's what it is more than likely. Same problem and dmv asked for smog check. Some dude programmed my nissan for 200 in Los Angeles
Fixed problem but I had to run car for about 100 miles before smog
Thank you for sharing a great video. Very helpful.
How did you not notice that your air filter rubber seal was damaged? Air can leak pass that seal.
Thank you
awesome. thank you sooooooooooo much. heading down for some cleaner right now. (and a filter, lol)
Thumbs up for the birdy!!
After replacing the sensor if issue still persist. Does cleaning throttle body will resolve it?
Ty 👍👍
Dec 2021 Thanks JJ
The bird was great. Thank you for this. My hubby passed and he used to take care of my car. My light also went on so i will do all you suggested. Any suggestions on why my 2011 altima is burning oil? No leaks.
Check your valve cover gasket
Very good video would you tell me where is your garage located because I have Nissan Altima 2013
Need help I have 2013 Nissan Rogue I change the mass air flow sensor but I try to erase the check engine light but turns on right away again
Thanks for the video
I live in Atlanta where is your Garage!
I will try this! So right after it's done the light should be off? Or do I have to drive it like 10 miles or so to make the check engine light go away?
nice
Need programming after cleaning??
To get it off did you use a torx bit on the ratchet if yes which size
Phillips head
Could you guide me where evap sensor located in nissan altima 2013 ? Do I need to open dash to replace it?
Assuming you mean the evap purge solenoid, it is on top of the intake manifold towards the back of the engine. You can do a 9 or 12v battery test to see if it closes. If you are replacing that change the pcv valve right next to it.
What about a p0101 and has a new filter, new MAF sensor? Clean air box, cleaned throttle body. I usually reset the battery and the check engine goes off any my fuel mileage stays higher then it kicks on and drips drastically. 2011 xterra
Pcv valve?
Well, I put a new oem maf sensor and clean filter. Still getting the code. Any suggestions?
Change pcv valve as well with nissan oem, pretty cheap.
I changed mass flow air sensor, due to check engine light code, on a 2011 Nissan Rouge Check engine light came back on. What should I check replace next?
You should scan it before replacing stuff to see what is them problem
Hello how would you recommend cleaning the air filter if it is dirty?
Air filters are cheap, replace them. Only if you have k&n filters you can use the cleaning solution to reuse them.
Great video! I changed out the mass air flow sensor but the same code came back a few days later. Anything else I should check?
Change air filter, clean throttle body, and replace pcv valve with the OEM.
@@JJCentral-DIY appreciate the quick reply!! Thanks
This was an awesome tutorial!, Question tho, I did the cleaning, and felt a difference on the idle and throttle, but the engine light still on. Does definitely mean I need to get a new sensor or do I have to reset something
You gotta reset so it relearns and buying a new one i would suggest
@@scorpion_fps how do you reset? I just cleaned mine but the engine light is still showing, even after driving it around (maybe 10 miles or so)
My 2014 just recently started giving me the code but it comes off and on with no real pattern. I’ve replaced the mas twice any idea what else it could be?
If it is not the maf, then it's either the pcv valve or a leak in the air intake house. Also sometimes it needs a software flash when you replace the pcv valve.
jjcentral I appreciate the fast response!! thanks I’ll definitely give that a try
Excellent video. I have a question for you. I have a 2012 Rogue with a MAF problem p01 01 code. The Nissan dealer replaced the MAF. I replaced the air cleaner. I did not replace the PCV valve yet. The dealer I go to tells me they cannot fix the problem any more than they have because they do not have a Master Technician??? I am going to have to travel a ways to get a dealer with a Master Technician. The engine light has gone on twice now. It is supposedly fixed now. If not and the light goes on again and the car seems to run fine I want to turn off the engine light. I purchased a Walmart Hyper Tough HT 100 code reader. It is not much on instructions. It connects with your phone via Blue Tooth to give an explanation of the code. I do not need an explanation and I just want to turn off the engine light. My question is, do I have to use the Blue Tooth feature with the HT 100 or can I just plug it to the plug in the car, turn the ignition to on, read the code, and push the red button to clear the code??
Thank you, Tom Spero
You can clear code with the device itself. But once you clear if it comes back after driving, it is best not to clear after that due to the fact that the master tech will read not just the code but the freeze frame of what was going on when the code was written.
@@JJCentral-DIY Thank you very much
I cleaned my sensor and changed air filter once I had the Check engine light reset it came back on a couple days later do I just need to change the sensor?
Try changing the pcv valve next before you change the maf sensor.
@@djsimma8617 Dealer service bulletin recommends a flash after changing any sensor. I have had plenty luck turning off the light with just code reader and using generic parts. The sensor is just sending low voltage, why does it need to be reflashed? On the other hand a full module change airbag, pcu, ecu, abs etc.. sure definitely needs reprogramming to accept the newer module.
Thank you for the video sir.
Does the engine light go away after you clean the sensor. Or it needs to be reset manually?
It needs to be reset for quick erase, if not it will go through few cycles that may take up to a week to go off by itself.
@@JJCentral-DIY thank you.
So which way is better? A quick reset? After that if the the engine light pops up again, I know the error could be due to something else.
@@hulong0205 that is correct. You erase and see what new or old code pops up. That will tell you if you fixed the root cause or the symptom.
@@JJCentral-DIY Thank you so much! Very helpful information!!!
Could you use rubbing alcohol in a spray bottle?
Rubbing alcohol, brake cleaner and other quick evaporators leave a little residue that may affect the sensor, thats why its ideal to use the specific MAF sensor cleaner.
How long after til the light goes away? I changed it today but engine light is still on
Disconnect the battery for few minutes and put it back. Ideally use a code reader to erase and see if it comes back.
Will this code cause your car to not start properly for example Once I turn my car off I have to let sit for about 30mins before it will start again.
No, that is usually a fuel problem or the air intake is severely blocked in someway. Start by checking your air filter.
Same code im lose gas like crazy. Happen 4 years ago will replace maf with oem. I used oem from junkyard last time
And for the Nissan Versa note is the same thing?
Versa has a smaller engine so placement of the sensor could be different. Generally same procedure as long as you find the MAF sensor.
Did you have an issue with a/c
Happened to my 2014. My compressor seized up right after warranty
Don you have to reset the code or will it go away
It should go away after few cycles of driving if the sensor is reading correctly. You can also erase the code and the monitors will relearn.
What kind of screwdriver did you use to get the sensor out
Phillips head
What happens if you replace the mass air flow sensor with and OEM. The engine light still come one again even after the code has been erased?
Here are your options, Check the throttle body, if it's dirty, clean it. Check the connectors and the wiring at the MAF sensor. If you have a scan tool, look at the short fuel trim numbers at high and low RPMs. If the short fuel trim (STFT) goes lean at low RPMs, it's a sign of a vacuum leak. A leaking purge valve, as well as brake vacuum booster can also cause this problem. Check the MAP sensor; it's used to check for rationality of the MAF sensor. If the oem MAP sensor is faulty, it also can cause the code P0101.
@@JJCentral-DIY What about if the MAF sensor is reading 195 g/s constantly, and sometimes drops to the normal range 6-9 g/s? Is this a sign of a failed MAF, or is this a wiring issue? ( I ask because the car had the MAF replaced a year ago)
@@roofcamper3473 at idle it should read between 2 and 8 and at full throttle it will be 30 to 40 times as idle. But if yours is putting 195 constantly, it is stuck in full throttle open loop. Clean it, if not replace it.
Have a 2011 Nissan Altima. Only 75k on it. Same issues Check engine soon light on. Traction control engages out of nowhere. Shaking etc. an absolute mess. Dealer said they fixed it only to happen again days later. Brought back for 3 weeks gave me loaner now got car back last week and check engine soon light is back on traction control engaging out of nowhere. Bought a cleaner today trying to fix myself. I hope my car is not a lemon.
Read the codes and see how many codes are there and what are they.
Did your resolve your issue? What was the problem? I am having traction control issues as well!!
Did the check engine light just go away for did you have to reset the code?
Reset the code and didn't come back. If it comes back then change the pcv valve and mad sensor.
I also have a 14 Altima and it has the check engine light and reads the same code ... cleaning it didn’t help and I replaced the MAF sensor with one from autozone and it still comes up and my car hesitates when I try to accelerate . Took it to a mechanic and he said I need to buy a MAF sensor directly from Nissan , he didn’t charge me because he knew the check engine light would come back and it did :(
Elena Davalos did you end up fixing the problem ? My car is doing the exact same thing
The Best Of Fortnite well I ordered the Nissan part 275$ (auto zone was 180$) but the mechanic didn’t work all last week because it rained all week . Haven’t called him this week to replace the sensor . Check engine light is still on but since he gave it back to me my car had not hesitated at all and it’s ran very smooth. But I hate seeing the check engine light
Did replacing the sensor fix your problem?
Efrain Carrillo once I had the genuine Nissan sensor put in the light was still on but it went away a day later and had not come back , the lesson I learned was just buy genuine Nissan because the after market sensor I got was a waste of money .
I have the same code with my 2013 altima 2.5. I replaced MAF, air filter, and PCV valve with cleaning Throttle body. Still have the code. Now I clear the code whenever it shows using obd2 scanner. Strange thing is that the code appears more than 20 times, but it shows only when my car starts up. The CEL never pops up during driving. Will Reprogramming the ECU fix the problem? Could I ask the dealer to update the ECU program without diagnosis of the car?
Yun Gu Lee I have a 2015 sentra with same issue. I found out there’s a bulletin out for the issue. You have to take car to dealer and reprogram the ECU.
@@jcr23bv89 Because the dealers charge much money, I want to do everything that I can do before taking car to the dealers. Does your car pop up P0101 only when start up?
@capitalismforme There is no visual crack in the air intake hose. Also, I think P0101 may pop up during driving if there are cracks.
I got the same code 3 times. Ended up cleaning it like so and got the code again. Second time I purchased whole new band name sensor. Now I'm getting the code again. Someone help. What should I do?
I was told the ECU had to be updated after replacing depending on your car. Not sure if that’s the issue but maybe?
same thing is happening iwth my car, did you ever get it fixed??
TheAlife18 So according to Nissan this happens a lot. The code ended up resetting on its own. I was also told if you put a new sensor in it takes a while for the car to get use to it. So drive as normal and it SHOULD reset on its own within a week or so.
You can also pull the ground on your battery and let it sit for awhile draining the computer of it's power, thus resetting it. If it's a hard fault or code it will still be in the memory, if it's a soft fault or code it will erase and relearn accordingly.
Clean you MAC
I changed mine today but the check engine light is still on. Any suggestions?
It will take some time before your check engine light turns off. You need to drive the car for couple of days and then see. You can also turn it off using a scanner.
@@JJCentral-DIY okay that Answered my question
Hola yo tengo el mismo problema en mi nissan 2013 lo yeve hacer el smog check y no paso me dijeron que tengo que cambiar el sensor del que usted hala y que ban a reprogramar la computadora es verdad eso k ocupa reprogramar la computadora me cobran 450 dolares
No todos los coches necesitan flashear el PCM. Depende del sensor. Si se trata de un reemplazo OEM directo, no es necesario volver a flashear. Si se trata de una pieza no original, entonces sí es necesario volver a actualizarla.
Was that the cure long term?
I wouldn't say long term but a year or two and another cleaning before you replace.
I was quoted $430.00 at Napa auto parts and canadian tire don't even have a listing for it
Update, refer below for old posts. Replaced air filter, cleaned entire airbox, no vaccum leaks, not a bad ground to the maf. Cleaned the throttlebody, light came back but restored some mpg. Replaced maf with a brand new hitachi maf, no reprogram from the dealetship and mpg went up even more and the light is finally gone for good. Ended up being the mass air flow sensor needed replacing, the old unit ran the car, no symptoms other than a missing a few mpg average and a CEL. Problem solved.
Thanks for the update, I don't believe a straight resistant measuring sensor like this one needs any dealership reprogramming. A replacement one should fix the issue. Just check the continuity and clean up everything.
Why did you replace maf? Didn't cleaning the maf resolve the problem?
I’m experiencing the same issue, cleaned sensor twice a light came back on. No drivability issues other than less mileage.
@@blainemcdonald6972 I cleaned it because it had never been cleaned before at 65k miles. I was hoping it would fix the issue. It improved it slightly, but all in all, it was due for replacement.
Im going to do this right now
The MAF is not the fix for this DTC. There is a SERvice bulletin for that p0101 DTC. You have to replace the PCV valve and reprogram the ECU. IF you have an oramnge PCV valve than the DTC will return eventually. Replacing it with the updated part (its Black) and dont use an aftermarket part, then the ECU needs to be reprogrammed. I work for Nissan.
Good to know. My DTC hasn't returned in the past 10,000 miles after the MAF replacement. If it comes back I will explore the pcv valve option. Are you saying that if I replaced the pcv with the genuine Nissan part, I don't have to reprogram the ECU?
@@JJCentral-DIY no im saying There is a Service bulletin that applies to your vehicle for that particular DTC. That requires PCV valve (updated part number) and reprogram. If the MAF fixed it. Then i would not worry. Its possible your MAF was bad. Typically i find that the MAF sensor is not usually the cause of that DTC. Most of the time its people using cheap aftermarket air filters that dont fit properly allowing dirt to get into the MAF sensor or some type of intake boot leak. Usually just cleaning the MAF and putting a quality good fitting air filter in (doesnt have to be Nissan Just has to fit properly) works. I just did a video on my channel on a Murano with the P0101 DTC. check it out.
@Travis Butler no, it needs a new PCV and a reprogramming.
if you put a new MAF on (unless its OEM) you will end up with more problems.
Auto Fix Pal any idea would could cause the light to come off and on? I replaced the mass sensor twice and the code keeps coming on I’m getting a little frustrated and my mechanic doesn’t have an idea but after reading this do you think it could be my pcv valve?
From experience for what ever reason, Nissans and Infinitis don't play well with aftermarket parts. If you end up having to replace your maf sensor, get one from the dealer or original factory part online. Paying a little more upfront, will save you in the long run when you have to replace the aftermarket part.
Mine is OEM Hitachi $560.00 dealer price. After market does sell the same Hitachi MAF sensor. Price is $ 385.00. Caution do not buy cheap air filters that are mentioned here. Nissan filter is around $35 better filtration and more durable, you get what you pay for.
man crapy vid but well worth the time, really not a critic, I am actually grateful for your info

Here are the possibilities. Fix in the sam e order 1. Dirty, obstructed, or faulty mass air flow sensor 2. Damaged or disconnected air intake boot 3. Clogged or improperly installed air filter 4. Vacuum leak 5. Clogged catalytic converter / restricted exhaust.
@@JJCentral-DIY I will let you know thank you 🙏🏼 I did change the mass air flow sensor and the filters I’m praying it’s not the catalytic converter
@@JJCentral-DIY I heard that it could take a while to get back on until the car hits the correct “speed” test for it to reboot? Is that true like if I drive 45mph for like 20 mins straight?
Do you know everything about Nissan's
I have owned enough Nissan's to understand what's going on. Whats your issue?
I have the same code on my 13 2.5s Altima. Other than the CEL being on all the time, there are no symptoms affecting performance ot driveability. Im gonna clean the maf and replace air filter and see what happens.
To permanently fix the problem, you need to take your car in to stealership and get your car reprogram. It will stop the high rpm
@@truegrizzlesfan2292Ive read that a dirty throttlebody or a leak of air somewhere, possibly a vacuum leak, maybe bad ground to the maf. The "reprogramming" may infact be them cleaning or fixing a mechanical issue. Its a well kept secret. Maybr hitting a bump causes voltage drop due to faultu wiring and it takes the computer sevetal days to turn off on its own. Which is what my car does. It constantly turns on and off, still no performance loss or any symptoms. I cleaned the maf twice and it stayed off for longer but came back. The 2012 tsb issues seems to correlate to newer year altimas aswrll
@@shaneblack3149 oh k. I know replacing my mass air flow sensor and reprogram fix the problem for me
@@truegrizzlesfan2292 I agree, I'm trying not to go that route and may be able to find the issue myself. I know taking it to the dealer will fix the issue and it may be the maf and reprogram, but if it is more simple than that in my case, i will share my experience to hopefully help a stranger save time and money.
@@shaneblack3149 Needs to have PCV valve replaced (updaed part) and ECU reprogrammed for a permanent fix.

I need to know how u fixed it
You didn’t show the car with the code clearing
pro tip. if it isnt the air filter or sensor or harness, it is 99% chance its the ground screws
Could you be more specific on which grounding screw you are talking about? The main battery negative grounding screw?

Anyone who watching this video, take your car to the stealership and let the mechanic reprogram your ecm. You can't reset the ecm Bec the mafs will not know if it's a new part or an old one I had this done to my car and it fix the problem. I paid like 120 . Lastly, don't let the stealership upsale you either

@@michaelarthur8803 you gotta take your car to the dealer and let the dealer reprogrsm the ecm. Reset the ecm will NOT work. I paid 120 and well worthy
sorry u paid that dealer price on the MAFS. i went to o'relly auto parts and paid 135. I was mad about that price. bec my code was showing again. until i took my car to dealer and had them reprogram. I honestly, believe if I would used the can to spray my MAFS and then had the MAFS reprogram it would fix the problem. You live and learned.
By the looks of the engine compartment it needs some serious TLC UNDER THE HOOD.

Looks like some one's OCD is challenged. Lol. I did clean out the box, but the point is to show the process of elimination and didn't want to focus on air filter. Also filming one hand and working on the car with the other is challenging, so you will see a lot of edits and no mentions.
