This is the best video I have watched on how to clean the MAF Sensor and I am going to try and clean mine ,will get clearer and I hope it solves my problem .Thanks you sir for your explanation and the video !
This happens to so many Toyota cars because people have always been told: You buy a Toyota and the only thing you have to do is put gas and change the oil, and that is exactly what they do, then you have neglected maintenance like in this Camry
You are talking about me. My 2003 Tacoma 280,000 Miles has original coolant and brake fluid. All the belts are original too. I couldn’t get “CRC mass air flow sensor cleaner “ anywhere these days. No Walmart, AutoZone, nor O’Reilly. So I am using something else O’Reilly guy recommended “Lectra Clean 3000” even though the can says “ Not for Automotive use”.
@@chonghwang8028 Driving around with 280,000 mile, 19-year-old coolant is hard to believe. Coolant becomes acidic with age; I'm surprised your car hasn't fallen apart yet.
@@chonghwang8028better change that serpentine belt. Whether you think you need to or not. There's got to be some small cracks in it. I've changed mine long ago. I have 175k on my Toyota FJ. I had to change the alternator about 3000 miles ago.
NOTE : Remove the O Ring before cleaning. The spray / chemical can cause the O ring to swell making the O ring very difficult to go back into the intake port. Use a small pick - carefully remove the O ring. Clean the MAF - dry and reinstall the O ring. Preferably wipe a thin layer of silicone grease on the O ring before re installation.
@@bebo5558 My statement is a generally good practice. When you work with as many different fluids and cleaners as I do - it's a general practice to remove o rings prior to prevent them from being damaged during cleaning.
I find a quick spray and let it sit for a few moments to soften up the deposits then a final spray to wash uses a lot less spray. I've never used a half can on a MAF myself.
Thank you for an excellent video. Very valuable tip that engine will initially idle high after cleaning and once computer learns new information from sensor idle will drop down to normal.
Thank you for sharing. I have seen a few videos from others besides you previous videos. This is the BEST quality video and explanation of techniques. May you have a happy and prosperous New Year!
Did you do a video showing how the engine was working prior to cleaning the MAF sensor? It would be nice to see the difference in rpms before and after cleaning.
What a great video. My mass airflow sensor went bad because a stinkin squirrel made a nest inside my engine compartment of my brand new Toyota 4Runner and shoot through the wiring harness leading to the mass air sensor. I drove the car for a little over a month with a bad sensor and that made my mixture bad and dirty the heck out of my sensor. I had to buy a new connector and rewire it myself which wasn't that big of a deal but it still didn't fix it until I clean the mass air sensor. Just a note that you can have for yourself and give to your subscribers is how to keep squirrels out of your engine compartment. Buy some peppermint essential oil and put it in a spray bottle with water about 40 drops per 16 oz of water or a liter maybe is what you call it. Spray it all around your engine compartment and the squirrels will stay away. It works very well but you can't drive your car for about 10 minutes until that oil dries because your engine doesn't like burning peppermint oil
I have talked to more then one professional mechanic that have told me that they OFTEN has use break-cleaner, and done this for many years; the type that totally evaporates.
On my 2000 Corolla, this is easy to access an remove for cleaning. Use ONLY electronics cleaner spray ... NOT brake cleaner. The 2 small screws that hold the MAFS on are going into plastic, so be careful and loosen the screws to remove them with fingers and do NOT drop the screws. Set them aside safely for re-install. Do NOT forget the inside 2 wires to clean that are unseen inside the 'barrel' ! Clean them too ...and a MAF Sensor ic cheap to buy ... much like a PCV valve is cheap and easy to replace...
Outstanding job, as always. I would be interested in hearing your thoughts about different Toyota models and engines. Which ones perform better, reliability, ease of maintenance, etc. I've had a tundra for 19 years. Still runs good, but I'm not looking forward to replacing the starter if it ever goes bad.
Awesome dear friend. Thank you so much for sharing how to clean MAF sensor. If you could show us the video about how that works after cleaning it. Thank you.
I'm driving my sister's 2005 V6 Camry right now, and earlier got a check engine light with code P0174. Didn't hear any hissing, and car wasn't experiencing any sputtering or anything, so I pulled out the MAF Sensor, and sure as shit, it looked EXACTLY like the one in the video. Went to the auto parts store, bought a can of CRC for $11, and in 10 minutes, it was good as new!
Boom! This comment is what I was looking for! I have the check engine light come on and similar error code (PO171) on my vibe. I think I found the solution and will buy and do this also. I'm praying it will fix it and happy new year also!
@@yo-gx6gn No! Sadly.... I fixed it by replacing the intake manifold gasket. On the matrix, vibe and other Toyota's the gasket is flat and was a design fault. By replacing it the car runs perfectly again. Scotty kilmer has a video also called "Toyota won't fix this" or something similar.
@@yo-gx6gn It may work. My problem was air leaking into the manifold gasket. The Toyotas have a design problem and the gasket leaks air. What car is it and do you have an ODB tool?
Nice and very clear demonstration is perfect. Sir can i ask you if you have idea why my car innova deisel 2011 is not start even the fuel is good work but i think the injector is not work what is the possible cause or problem of this thank you very much
You can use isopropyl alcohol. Drip a few drops on the 2 wires hidden right inside. The stubborn carbon deposits just won't come loose. Use a pin to glide over the wires to dislodge the carbon. The wires are tough enough and its not like spider web fragile. When you are done, you will see 2 shiny wires with something cylindrical in the wire's center. I put back everything and it works like new and awesome acceleration. Idle is at 750 rpm and absence of rpm surging or engine dying off. CRC spray for MAF is just overpriced. Just don't use cotton buds or something that will leave traces on the wires which gets heated up and it will burn if something is stuck there
Nice! Going to clean my 08 Scion xB, lately the rpm go over 4k rpm on cold start hopefully this will help. Might also need to clean the throttle body if this not fixing it. Otherwise vehicle running fine just rpm go up high on cold start and after a few seconds or minute it's back to normal. Thanks for the tip.
In my area MAF sensors for 4Runner 1988 3.0 liter 3VZE engine are not available, even remanufactured ones. The cheap Chinese ones are apparently quite useless. Is there a good reputable competent source for remanufactured or Denso equivalent MAFs for this application? Please advise. Several people may have need for these. Otherwise cars will be undrivable.
My 2000 2.7 4runner was stalling when slowing down. I did the throttle body cleaning as well as MAF cleaning. Still stalls at red lights. Any idea? I'm going to clean MAF again, how long do you wait before reinstall?
I cleaned mine on my 2019 Toyota Tundra..why do they put white paint over the top of the screws. Had to buy new screws…crazy. Thanks for sharing your videos
I have a 04 Lexus LX470, got a can of this MAF cleaner, it says do not on maremma vortex sensors and on Lexus vehicles, just trying to make sure it’s safe to use, the maf sensor does seem very similar shown from this video, thanks!
I have a 02 Sequoia. Code came up for Mass airflow sensor . I cleaned it. Cleared code but code comes back. I replaced it and cleared code. Code still there. Dissconnected battery. Waiting 10 min. Trying to see if this will clear it.
So where the screws go in as I was screwing them in one of the brass threads popped out of place as I was tightening the other side and I can’t get it to tightening without the thread popping out
Clean the fuel injector with fuel additives; is it about the time to change the engine oil ? How about the in-take air filter ? If all of the above have been tried out, then it will come to cleaning the throttle valve, checking fuel pump pressure, checking catalytic converter restrictions and exhaust pipe restrictions, checking oxygen sensor, checking marginal misfires, checking compression leaks, checking carbon built-up in combustion chambers cylindrical surfaces.
Sir, the big one that you was starting clean it is just an intake air temperature sensor. The actual MAF is the two tiny hot wires that are surrounded by blastic. Please, make another video to make people notice that
I've seen alot of these being sadly thrown away due to oil contamination on the electrical contacts. (code 24, 31). 🤦♂️. Good idea to clean them too incl. harness connector.

If you change you engine air filter regularly you won't have to do this. My camry is 11 years old and the MAF was spotless.
I feel like I’m watching a cooking channel with your beautiful narration
close-up super-slow-mo of cleaning spray. 10/10 would watch again.

Who cares about the 0 ring? Take that Shit up with Bilbo Baggins or someone else who cares.
You dont have to remove the o ring.
Poor attempt at trying to be relevant by adding a non relevant comment.
Mixter. It says right on the spray can, safe for plastic and leaves no residue and O-rings are very chemical resistant! Your statement is false!

Just cleaned MAF on 99 Tacoma 2.7l- Worked great! Thank you for the pointers.
I just love your shows, I can just listen to your voice to be honest, it's very soothing

It’s not that bad I replaced mine 5 months ago. Tom me 4 hours
Thanks. Good to know.
I really liked the slow motion video on that one.
Pervert.
great demonstration
the other important thing is to let it dry naturally and not use any compressed air
Awesome dear friend. Thank you so much for sharing how to clean MAF sensor. If you could show us the video about how that works after cleaning it. Thank you.
Thank you for this video in slow motion. I felt very comfortable following your steps.
Tnk u best explanations..im from South Africa
I love your Videos your explanations are great and honest-Thank you my friend-HD
Will the alarm light turn off itself after cleaning?
Could this be why i may have P0171? I took out MAF and it is dirty. Should i buy the cleaner n give it a try??
So hepful and entertaining, thank you!
Just cleaned my MAF sensor (had -10% LTFT. Now improved to -5%g). Amazing for 5 mins maintenance.
I used a Liqui Moly brand MAF sensor cleaner spray.
Same here my LTFT is now 4% but STFT is still 19.5%. What’s wrong?
Thank you for your expert advise.
Do I need to disconnect the negative terminal of the battery if I clean the maf sensor?
Excellent video
can we use different brand of dirt remover such as WD40 to clean the airflow sensor?
Attention! cleaner spray will destroy the MAF gasket. Clean w/o gasket on the MAF or protect this. Keep going.
Great video.
Can we use Contact cleaner? (electrical contact cleaner)
No
Everybody says to only use maf sensor cleaner. This is my first time doing mine so I watched a ton of vids.
Thanks for the video, Very helpful.
Can check engine light stay on by Having a dirty air mass flow?
idk if it's the accent or the energy, but I'm crying over here man xD

Might be your fuel injector too
Can the carburetor cleaner be used, as they dont leave any residues too. Out of curiosity, what about WD40, can that be used too?
Can we use break cleaner?
Do you have to disconnect battery first?
You mentioned shaking after cleaning. Can you use compressed air?

How often would you recommend inspecting and cleaning the MAF sensor? Every 30,000 miles? The owners manual of my car does not mention this component.
I personally do our Toyotas every time I change the air filter, at a minimum.
Very informative. Do you recommend cleaning or replacing anything else?
Hello .. is toyota verso 2016 diesel 1.6 same as toyota corolla .thanks
How long should I wait to put it back after cleaning it 🤔?
If you change you engine air filter regularly you won't have to do this. My camry is 11 years old and the MAF was spotless.
Oops! I had cleaned this sensor with throttle body cleaner a few days back ....does it mean that my sensor is bad now ?
Several mechanics say CRC Electrical Cleaner is safe to use on MAF too??
any problem if i use a electrical cleaner that evaporates ?
Don't brush it. Don't touch it. Don't remove it. Don't look at it! lol j/k ;-) This guy is the best.
Should I need to disconnect the car battery before cleaning this sensor ?
I've heard u have to
Thanks you so much for sharing your knowledge

YOU ARE NOT SUPPOSED TO SPRAY THE MAF UPSIDE-DOWN. CHEMICALS MIGHT GET INSIDE THE COMPONETS
how long do i leave it to dry please at 7 mins 10 sec ?
What about 99% isopropyl alcohol? Will that work

Just Superb 👌
Thank You, Bro! What else must I do, like on a 2012 Prius V, if this doesn't solve it? On an OBD II P0172 trouble code, Brother?
Is it good to use Electric contact cleaner spray too cz i cannot find mafs cleaner spray in my city.
Hi. Can I use contact cleaner spray? For my rav4 2008
Wasnt you suppose to disconnect then reconnect the battery for the Ecu can recognize the clean maf to updated specs?
You can do that if you wish, sure. Or just drive the car for a while and let it recycle through the system naturally.
I have a 02 Sequoia. Code came up for Mass airflow sensor . I cleaned it. Cleared code but code comes back. I replaced it and cleared code. Code still there. Dissconnected battery. Waiting 10 min. Trying to see if this will clear it.
Can the MAF of the 2013 Chevy Impala LT be cleaned like this? It looks different.
Another well informed video . What is your opinion on cleaning O2 sensors as a preventative maintenance practice?
So where the screws go in as I was screwing them in one of the brass threads popped out of place as I was tightening the other side and I can’t get it to tightening without the thread popping out
My car is still hesitating when accelerating at slow speed after changing new maf sensor and spark plugs. Pl advice. Tqvm

Hi..can this cleaner be use to air flow sensor for mitsubishi triton @ L200 (year 2017)?
EXCELLENT video !!!!
Make sure it's completely dry before you reconnect the plug.
Please where can I buy the cleaner
what if I touched the sensor with a soft brush?
Does the o ring need to be lubricated or the housing lubricated to prevent dust or the sensor sticking
Can I spray the connector area I did it and my truck still shakes
How long does it take to dry?
30 minutes
Very imformative
