How to clean a Mass Airflow Sensor. Mass Airflow Sensor cleaning can increase fuel economy, stop hesitation and stalling, and shut off your check engine light. This is a simple procedure and in this video I go in-depth about cleaning the sensor and I take readings from an OBDII scanner to show before and after cleaning the sensor.
A mass airflow sensor gets dirty because of oiled filters such as a KNN air filter, air filters that are not replaced often enough, and dusty roads (salt, sand, pollen, etc). Symptoms of a dirty MAF sensor are hesitation, poor idle, bad fuel economy, and stalling. You can also get a check engine light with codes P0100, P0102, P0103, P0104, and P0105.

Average Fuel Economy for the month before I cleaned the sensor: 17.5mpg
1 fill-up later: 18.97mpg
2 fill-ups later: 20.86mpg
3 fill-ups later: 19.10mpg
4 fill-ups later: 20.1mpg
5 fill-ups later: 19.13mpg

Is Contact cleaner/ Electrical cleaner spray, the same chemicals as MAF spray ?
19mpg? Damn i thought this mazda would be getting good gas. Atleast it aint my 91' stang that gets 8-10 on a good day
Hi does the engine have to be cold when cleaning the maf sensor or can i do after driving thanks
19 mpg , I know gas is cheap in America but , wow , i'd be crying.
Nicely done.
Not sure if you check you old videos. Think this could cause my Outback to stall when I have the clutch pedal pressed? It runs fine while driving. Just when I come to a stop (or press the clutch in to come to a stop)
Why wouldn't you remove the sensor from the airbox to clean it? Seems like would be much easier that way.
Excellent ,Excellent video. !!!!!!!!!!!!!! Great demo, great simple explanation. Step by step. Thank you very much !!!!!!!
Can I use air intake cleaner instead of mass air flow sensor cleaner??
Is there any chance that a MAF may be causing issues due to being faulty or dirty but without throwing a code? I am thinking of taking my wifes off her beetle to clean it as her car struggles to start and it lumpy when first started.
Hey Chris fix😀 I took me 2005 Chevrolet Malibu 3.5 L engine and needed to get a smog test but it failed the test 😢 my obd 11 reader says it's a cat, Evap, Egr issue can I check or would it be fair to say to clean The MAF first to see if it's going to clear my emissions system 🤔???
Thank you for being thorough most people don’t do a before and after.
Outstanding presentation. Reminds me of military instructors. Nothing to question 👍🏾
Sounds alot like contact cleaner 🤔
Someone used 70% alcohol to clean their MAF and it appeared to work as well. Well, I guess if person does need a MAF cleaner 70% isopropyl alcohol should work as a good subsitute.
You're the man, ChrisFix. The process worked a treat. Easy to follow, easy to do. Nothing beats a late-night, high-speed "diagnostic" ride. Had to test the throttle response. Lol.
Hi Chris, you say to clear the code after the repair and if the light doesn't come back on, then it is repaired.
How long should it take for the light to return if there is still a problem ?
Also, I think I heard that you can just go ahead and drive it, and if the problem is fixed, then the light will just go out.
Is this true?
If so, then how long should it take for the light to go out?
