THIS is how DIY maintenance videos should always be done. Simple and to the point with some subtle entertainment. Thanks! ('04 Taco 2.7L 4 Cyl, 5speed)
I had a code Po420 before. I put a bottle of B12 Chemtool into the gas tank. After that, I had 2 codes, Po420 and Po171. After replacing the catalytic converter, Po420 gone and Po171 was still there. I followed this video on my Honda 2009 CRV last week. Cleared the code and drove 400 miles. Today I passed the smog test. Very happy.
Had this exact issue. Took it into a place without actually reading the codes myself and they quoted me $1,200 to replace the sensor and spark plugs. Thank you for saving me the money.
Thank you so much for this video! I have a 2001 Nissan Pathfinder that was running bad showing the PO171 code. I had no idea what to do for months. I just watched your video and did exactly what you did. Now it runs great again! You just saved me a lot of time and money! Thanks again! Great video!
I hear it's also a good idea to disconnect the battery or pull the EFI fuse after clean the MAF to allow the computer to relearn using the improved sensor readings.
Thank you Fix It Angle, I have 94 T100 2.7L 5 speed with the same issue P0171, I cleaned the MAF Sensor the way you did and it worked. The engine light no longer on thanks again.
Nice video, thank you. I had the same problem with on a 99 4runner with the same engine. Turned out to be a rock in the gas cap! Popped out the rock, drove 5 miles, light went off and never came back.
@@carlosrrr2011 I fought that code a long time. I cleaned MAF twice, replaced TPS, looked for vacuum leaks...ultimately, it was the upstream O2 sensor that solved the problem.
Hi Bear, Thank you for the comment. I really appreciate it. I try to help as much people I can to they save some $$ and they are very grateful. I enjoy fixing cars...most of the time. LOL Have a nice day.
I was working on 2000 Corolla with P0171 code. MAF sensor PASSED idle test for flow rate per manual, however examining one of the resistors under scope 10X magnification revealed broken wire (so cleaning would not help in this case). I pulled new one (on PYP) from 02(?) Echo. It fit Corolla setup and connector configuration (despite different connector angle) and fixed the problem!
Hi mkrp4, wow that's great you found the problem and the new one fit and worked. This is good to know. Thank you for the comment as usual. Happy Holidays!!
I got the same code on my 07 corolla. Did some research and changed out my gasket for the intake manifold. I also cleaned out the maf sensor. Easy 15 min and 10 dollar fix.
I did finally figure out to clean the MAF sensor - after I did everything else. Such a simple thing to do and I never had an idea it was even a thing. lol
thanks, all the fixing on cars i have done i have never pulled one of them out and cleaned it.. never owned a scanner before and i just bought a cheap one and this is the code im getting will start there and try it.. thanks for the simple short video..
Hey great work you definitely know your stuff. One thing though you should wear rubber gloves. I had my blood tested and the guy showed me my blood on a super high powered microscope and said “I see you area exposed to a lot of chemicals “ and he showed me how the blood cells were clumping together and he said that’s from solvents. Just a friendly reminder, thanks for the awesome videos. Be safe
Mahalo for the info. Dont want to bash you. I don't think you should use carb cleaner on a maf sensor. Its caustic. You should only use maf cleaner. But I have a p0171 code and it's only reading 7gps at 2500rpm. I will try this first. Before replacing the maf
There is a coating on them and after washing the dirt off you allow new dirt particles to sandblast the rest of the coating away causing failure of the mass airflow sensor to be sooner this could be done if you plan on replaceing it anyway ..but if you dont you will half to clean it more and more often untill it fails completely . i.e engine wont start.
great work!! i have a problem with a car that has Ltft at minus 30% and no error(check engine). Engine runs rough at idle. it doesnt matter if it is at cold or hot. still rough!! what can i do ?? thanks!!
Awesome "free" fix! I fixed my 4Runner the exact same way except I didn't clear the codes afterward. I just started it up and watched the STFT go really negative (-30) countering the long term of +30...after a short test drive the fuel trims were back to normal, and after a a couple short trips, the check engine light turned itself off so there was no need to complete the monitors over again. Cool channel man, keep it up. Merry Christmas!
Hi Josue, Thank you for the comment. yes that is a better way to find out if cleaning the MAF fixes the trouble code. Merry Christmas and a Happy New Year!!
Cleaning the MAF is almost a requirement not long after cleaning and re-oiling a K&N air filter. Also, check for vacuum leaks when you get a P0171 if cleaning the MAF doesn't help.
I had a factory original filter on my 2011 malibu with 59000 miles. I changed it yesterday but the air box was filled with sand.. it takes a long time for the car to accelerate... will cleaning the mass air flow sensor help??I vacuumed out the box n put a new air filter on...please advice thanks
I have a 2005 Mazda Tribute 3.0 with 162000 miles. It runs great. The problem I'm having is that I get different miles per gallon for every tank full. On one tank full I will get 19 MPG, then the next I will get 15 MPG, then 13 MPG, Then 10 MPG, then 15 MPG, Then 19 MPG, and so on. Originally I used to get 20 miles per gallon. I have replaced the spark plugs, spark plug wires/coils, and every filter I can think of. I’m the type of driver that does not have a heavy foot. What is weird about this issue is that the gas mileage fluctuates so much. Could this sensor be the problem?
Great video. Got a 1994 v6 4runner that has the same code. Looks like a simple fix. I like your Guam flag. Lived there from 1996-1980. Loved it there. Hafa Adai bro.
I've got a 2000 Corolla and it was giving the same code. Changed the MAF sensor and still get that code. ST trim is like 5.5 but LT trim is 38.......fuel filter or pump maybe???
Hi got a Toyota Yaris GLS 1999 got a problem What I start the car it run then cut off But when I take of the air intake sensor then it run When I reconnect the sensor and start the car it keep cut off What could be the problem??
Hi bro. Was wondering if you could help me out. I had the same problem but instead of cleaning my maf sensor I bought a new one for about $100. After I replaced it, it still won’t start. Code said it was a fuel injector #5. I replaced all 6 and it still won’t start.. got a different code for spark plug in bank 1. I changed all 6 and now I’m not getting any more codes and it still won’t start. I even replaced the fuel filter hoping it’ll solve the problem but no luck.
Nesiian Jboii hi bro, did you try spraying some starter fluid into the throttle body? If it starts the problem is the fuel pump. If it doesn’t, you may have an electrical problem. What year make and model is your car?
Wow glad I found your channel. I have a 2004 Toyota Tacoma that has been occasionally showing this code. It only happens when the truck is a high speed for awhile. 85mph in Texas on our toll roads. The other issue is the truck falls on its face at more than 3/4 peddle of throttle and starts cutting out at 90mph. My truck used to run 105 flat out but there is definatly something wrong and would really like your opinion if you dont mind. Thanks for your time. Subscribed!
Always a great idea to do this when having any trouble with power, idle, throttle response. Dirty MAFs won't code, only broken ones will. so your often left scratching your head. Must uses sensor cleaner, not brake and part cleaner. 10 bucks will often fix your problem.
Thank you for your comment. Since 2002 I have been using brake and carb cleaner. I'm still waiting on friends and family to complain on a bad MAF sensor because of a wrong cleaner I used on their car. I have done this on many different makes/models. Is brake/parts cleaner really that bad? My 2004 Camry, I cleaned the MAF sensor every year using brake or carb cleaner, it has 200K miles on it. Same with my 2002 Sienna, with 180K miles. I honestly never replaced the original Genuine Toyota MAF sensors. I guess you can say I'm lucky? I proved it with this video. Did you have a bad experience when you used a wrong cleaner?
Fix It Angel brake and part cleaner is not safe for plastic and rubber (if you've ever gotten it on a rubber caliper boot you'll know this) also it does leave a thin white film behind which can cause increased resistance within the maf resistors. Brake and part cleaner will probably work, but it's not the best cleaner to use. For $10, I would rather use the sensoclean that way you have no worries about damaging a $200 part.
I do this every 30k as preventative maint. My suggestion to others, remove the rubber o-ring or do not spray it because it will be loose when exposes to the cleaner.
Hi angel, I originally had a maf code, and I tried to clean it it turns out I needed to replace it, mow it is giving me a code p0710 , what do you recommend I do now thanks
Great video....My truck still hesitates under heavy throttle ( no codes thrown) however, and does not fire when hot after sitting for 15 to 20 mins.....I have new throttle body, TPS, both crank sensors, coolant temp sensor...any ideas?
My Tacoma hesitates to pick up rpms 3× & up . replaced plugs coil , fuel pump injectors regulator filters timing chain. i replace everything on that engine 2.4 but Mas.sensor or computer 💻 .
Brother my 4 cylinder suzuki dzire have same code system too lean on bank 1. I had bad battery which I recently replaced, checked my air filter area for air leakage. Clear obd code but after some time code still pops up. My car giving awesome milage on cng gas kit but, not good on petrol. I feel my car running with very low torque and have low power until it reaches to some respectable speed.
hello my brother, I really like your videos, I watched almost everyone, but I have a question: do you think it's cool to get all dirty in the customer's car? Why do not you put a cover on the car seat?
Hello nice video, thank you for the info.. sorry one question, i have a sienna xle 2012 , is consuming a lot of fuel, 130 km half tank, the spark plugs are new denso original.. could you give me a hand with this please..?
@@FixItAngel Hello Angel, nice to talk with you, today i was trying to clean te maf sensor but is very difficult to get out of the place, how i can know if is good or bad? and the air fuel ratio sensor i dont sure wich is there are to many sensor jajaja this is the one that is on the escape manifold with four wires ?
Andrew Jeffrey you can use MAF cleaner. It's up to you. I have been using carb cleaner and believe it, brake cleaner too. From my experience, I have not seen a maf sensor break because of using carb and brake cleaner. I would have not made this video if it will break it.
you know whats funny i went to diagnose what a customer thought was a bad fuel pump... instead of spraying startING fluid after the maf sensor i sprayed it before the maf sensor and accidentally cleaned it that way... went to turn the key and the car turned on and stayed on Lol it still running today i tested the fuel pressure and it was at 40 psi so the fuel pump was good xD what im trying to get at is starting fluid works too LoL
hey, my friends 2001 tacoma has this same code P0171, and also has a catalytic converter monitor that doesnt want to complete, any advise you can give? His longterm fuel trim is around 22% any help would be appreciated.
this is so great. I loves the shirt Vegas sky timelapses. artistic license great. although you can probably chop down your driving selfie bits. don't eliminate them just more jumpcuts to show the lapses. and I swear that was flamingo going west into the sun towards Las Vegas Blvd. so how much were the strut labor? haha. I'm debating mine. 95% of the time they were ok. about three times out of six months driving it was a really big dip or a sharp turn where it bottomed out in the front and another time I don't remember what it was, not a speed bump more like another dip. small dips are fine however. potholes fine, if the car probably will be sold in 5 years, should the struts be changed? the airdam diverter under the car does catch sometimes going up or down driveways. it's that plastic half round under car spoiler. a 98 es300
