Does CRC Mass Air Flow Sensor Cleaner Really Work?

Does CRC Mass Air Flow Sensor Cleaner Really Work?

In this video I have a look at a Ford F-150 that came in with customer complaint of a check engine light. Reading the codes revealed several “lean codes.” A few quick tests leads us right to the MAF sensor. Can we clean it with CRC MAF Cleaner and PROVE it worked? Let’s find out. -Enjoy!

    I need one of those Gizmo’s, having sensor troubles on my old Tortus, how much are they? I’d like to see that done in a top fuel, you were getting close😁 Gotta a spare mas sensor in junkyard other day and new uncracked air cleaner box, my Vulcan was eating dust. New iacv and EGR pressure sensor, it was done. I’ll put map sensor on tomorrow, should cover all the codes I had

  2. ThedopestOliver on August 4, 2022 at 1:20 am

    Related to the charge: the car owner could have done it himself and saved. Mr.O always says "if I can do it, you can do it." He really could have done this one.

    $100 obd scanner
    $7 mass airflow clear

    Still a win win the cost was surly under $160 I hope 🤞🏾

    I don’t think that’s a good test for how well CRC MAF sensor cleaner works, as indicated in the title that that is what this video is about. Usually that’s for stuff you can’t necessarily see, not for obvious problems like a dandelion seed. First take tweezers, compressed air, something like that and remove that dandelion seed, THEN see what happens after that. Just MHO. But I’m still subscribed 😁, as of today, because your video, this being the only one I’ve seen of yours, is entertaining.

  4. Glenn Cordova on August 4, 2022 at 1:22 am

    Dandelion fuzz of death. It was lion 🦁 there.

  5. Jerry Simpson on August 4, 2022 at 1:23 am

    Would help clean that nasty air filter shoo nasty

  6. Slewfoot on August 4, 2022 at 1:23 am

    And a 30-06 too?? WOW! LMAO. thanks for the video🙂

  7. generic dude on August 4, 2022 at 1:23 am

    How much MAF cleaner is enough?

  8. C#PO on August 4, 2022 at 1:23 am

    You have a fiduciary responsibility to your family to maximize your income within fair practices. No one can accuse you of being anything but ethical and highly competent at what you do.

  9. Gene Foster on August 4, 2022 at 1:25 am

    25 minutes to explain a can of MAF air sensor cleaner.???????

  10. jim von feldt on August 4, 2022 at 1:25 am

    Getting 2 codes. P0017 and p0171. Chevy tb. Where to start troubleshooting ?

  11. paul kaufman on August 4, 2022 at 1:26 am

    I always enjoy your videos – LOVE your Attitude!! And, I always learn something. Thank You.

  12. RJB on August 4, 2022 at 1:27 am

    Had to get rid of my 1987 Camaro, in 1988, because three different dealers couldn’t figure out why my car would continue at speed after lifting off the gas. After selling it, a friend found out her daughters Camaro had the same problem and the cause was the mass air flow sensor. The car was a lemon anyway. Worse car I ever owned.
    You pay taxes in that town?

  13. thinkorthwim69 on August 4, 2022 at 1:33 am

    71 years old here and everyday learning more. Even my mechanics did not diagnose MAF sensor as why my car started then slowly died. After weeks of google and reading I find this useless POS is the reason . It reinforces to me the principles of KISS. Keep It Simple Stupid and the ONLY reason I can see for making all of this electronic gadgetry which does NOTHING to make the car run better as in the 60’s cars so easy to work on and fix but now they like to make built in bombs to make people have to spend thousands of dollars to keep their car running by fixing the crap they never even needed in the first place to make it a good ride. ANother GREAT example of this is the ABS modulator. WHAT a useless piece of crap it is and is only valuable if people who are tail gating or driving poorly have to slam on the brakes. MORE useless crap that does NOTHING to enhance car performance but EVERYTHING to do with draining your bank account. IMO

  14. CallMeLee on August 4, 2022 at 1:33 am

    Watching this one for review in October, 2021 – got so engrossed in the diag and teaching that when Eric got out on bumpy-ass, torn-up Main Street, I wondered out loud, "Didn’t Main Street get repaved a long time ago?" Why yes, yes it did, a month or so after this video was made IN JUNE, 2019. SMH, time travel via YouTube…

  15. Cody Tran on August 4, 2022 at 1:35 am

    Yes it can if its dirty, no it wont if its electrically broken.

  16. Morris Dugan on August 4, 2022 at 1:35 am

    How much of the problem would have been solved by simply blowing away the fluff that got into the MAF? I’m asking because it was the title that caught my eye, and I just bought some CRC MAF cleaner yesterday. I don’t have a OBD2 device to check the results; I’m just hoping to improve my gas mileage.

    I think your price was fair. You fixed the problem, and made sure it was really fixed, including a test drive. The cause – in this case some fluff – doesn’t make a difference. It would be very different if you had caused the hose from the air filter to come loose on a previous repair, but that’s not what happened.

  17. Matthew Morrone on August 4, 2022 at 1:38 am

    My 2000 corolla had a lean issue, cold starts it would start and stall right away… once or twice then stay running no CEL ,no codes🤬… the 99 uses a TPS while the 2000 uses a MAF. After a month of this starting issue and me scratching my head, the CEL/MIL came on, lean code. I cleaned the MAF sensor, never happened again.
    Even visual inspection down the flute, could see one clean sensor and the other resistor was filthy. Visually cleaner after using sensor cleans. Toyota using MAF sensors are known for this.

    You have 12psi baro??? Sealevel is 1 bar or 14psi….that doesnt seem right. I have a hard time trusting inputs

  18. Bike Life on August 4, 2022 at 1:41 am

    Love your videos, keep up the good work.

  19. Ronald Todd on August 4, 2022 at 1:42 am

    Very informative. My repair shop wanted $600 for a tune-up which included cleaning the maf sensor. But, I did it for only $100, including the cleaning, replacing plugs and wires and it only took me all day. My time is valuable just like the mechanics. Next time, I will probably bite the bullet and let someone else do it.

  20. R Astraquillo on August 4, 2022 at 1:43 am

    Dee Bee is right…..Do it yourself if you want it "for free". For example, got a toothache? Pull the tooth yourself or pay for professionalism.

  21. Doug Saint on August 4, 2022 at 1:47 am

    Didn’t follow directions on cleaning sensor…

  22. Guillermo Gomez on August 4, 2022 at 1:51 am

    People have some nerve asking if that’s billable. It’s not charity work, it’s a business. Don’t want to pay for work, find alternative means to fix your issues.

  23. John Iredale on August 4, 2022 at 1:51 am

    jeezus what a rickety clunky sack of shit lmao! just watching that test drive was stressful

  24. Art Denning on August 4, 2022 at 1:52 am

    And buy the tools.

  25. Ofc Bob on August 4, 2022 at 1:54 am

    Looks so easy to clean up a MAF sensor, but is there any need to do it if there is no CEL coming on about it needing attention? I have an Infiniti SUV with just over 100K miles.

  26. John Goins on August 4, 2022 at 1:56 am

    Thanks for what you do. I would love you to Work on my car. Can you.

  27. totypme on August 4, 2022 at 1:57 am

    You get paid for your knowledge. That is fair.

  28. Sprnklrmn on August 4, 2022 at 1:58 am

    Time is money. Can’t make a living if you don’t charge.

  29. Art on August 4, 2022 at 2:03 am

    So turns out “make your car run better with a little spray cleaner” does sometimes work. Scotty would be proud

  30. Joey B on August 4, 2022 at 2:03 am

    It’s your job u fix it you get paid even if its 15mins of work I dont mine paying as long its fix.

  31. Steve Vera on August 4, 2022 at 2:05 am

    wonderful video. the cost of that computer you use is what. suggestions on one a diy could buy and get the same results?

  32. Underground Subs on August 4, 2022 at 2:07 am

    You get paid for what you know not bc of how easy it may seem and yes the dealer would of charged for dirty rags too🎃

  33. Enrique V on August 4, 2022 at 2:08 am

    I say your charge is a bargain! Thank you!

  34. Mike Harrison on August 4, 2022 at 2:09 am

    Ugh. Significant exhaust manifold leak (that ‘Ford thunder’ you heard on startup) can lead to fuel trim issues as well.
    Had a few 5.4s in the dealership with modified intake tubes/oily cone filters on them that the tech finally convinced them to swap to OEM air intake parts instead of spending more money chasing their drivability issues.
    Fuel trim reset is ‘clear KAM’ on Ford OEM scantool and I believe SnapOn as well.

  35. starving artist on August 4, 2022 at 2:09 am

    That a bad highway you’re on there, sounds like it

  36. tube-dude on August 4, 2022 at 2:09 am

    Your *Autel MaxiCom* what is the exact model you have?

  37. Edwin C. on August 4, 2022 at 2:10 am

    I have the same codes p0171&0174 on my 03 ford E150 4.2 v6. My freeze data shows 25% on long term at idle engine warmed up to 190 rpm at 854. I give it some gas and the short terms drop to the negative digits meaning vacuum leak. But I’m stuck because if I let it idle without the air filter the shorts terms drops drastically and the percentage between both combined is less than 10% If I put back the *New* air filter the short trims go back up in theTeen’s. Any advice I would appreciate. I did smoke, propane, water spay, visual and can’t find no vacuum leaks. Cleaned the Mass air flow sensor, TB, changed the egr valve due to alot of smoke coming out when tested but nothing. PCV working fine. o2’s are monitoring correctly.

  38. Fito King on August 4, 2022 at 2:10 am

    You pay for the amount of experience someone has. It takes time and patience to learn all this automotive stuff. I think the 1 hr minimum rate was more than fair. I would pay that all day.

  39. john whitaker on August 4, 2022 at 2:12 am

    I have a buicl lesabre 2002 check engine light code says o2 sensor replaced one of 2 no difference. had it hooked up to a diagnotic tool said both o2 were were working. i tried spraying mass air flow seem to run smooth for a minute then went back to rough running.

  40. Mellow Guy on August 4, 2022 at 2:12 am

    Never apologize for charging shop rates. I’d have tossed another couple of bucks on there for the CRC spray cleaner too. I’m sure the parts store didn’t simply gift that stuff to you.

  41. tube-dude on August 4, 2022 at 2:12 am

    That Air Filter should be changed.

  42. WayneS World on August 4, 2022 at 2:12 am

    Weathermen are called “wrong”.

  43. Mikey Swerve on August 4, 2022 at 2:14 am

    Actually it’s not the rrrr nor the C it’s the bootE

  44. Segundo Slot Gambler on August 4, 2022 at 2:15 am

    Can a faulty mass air flow sensor cause a p1870 transmission component slipping?

    It also has lean codes.

    Gmc Sierra, it runs good on start up but then after a bit, it doesn’t want to drive anymore, pushing gas pedal down, rpm just goes up, and gears don’t change.
    Turn vehicle off then back on and it does the same.
    Any advice would help. Thank you.

  45. William Vangorden on August 4, 2022 at 2:16 am

    Sounds like you need a tire rotation ha ha!

  46. Elijahtree on August 4, 2022 at 2:16 am

    Great video, has anyone ever told you that you sound like beetle juice

  47. William Vangorden on August 4, 2022 at 2:16 am

    Chiropractors must be busy in your area I know they are in my area. Starting to think it’s quite lucrative considering that the roads are very bad.

  48. J. Mark Krzystofiak on August 4, 2022 at 2:17 am

    I bet you’re even overdue to raise your rates.

  49. Scott Moore on August 4, 2022 at 2:17 am

    Dam Skippy you should’ve been paid. Auto shit ain’t cheap!

  50. Santiago Elias on August 4, 2022 at 2:18 am

    ..is that chew tin in your driver’s side pocket?..and what’s up with you techs from the east?…mustie stores his wallet in his FRONT right pants pocket…you carry you wallet in the right rear…and your pocket knife in your front right…is it because of the whole time difference between east coast west coast..?..anyhow…you have one of the best vehicle repair Channels I’ve ever spent 2-3 hours watching…"wicked "awsome dude!.
