Thank You! Have a Mazda 3 08 manual and got the P0102 error code. Went to the auto store and said the MAV sensor had to be replaced at a cost of $550. Researched, saw this video, bought the MAV cleaner and followed the steps. The steel rods on the sensor was very dirty and probably was not reading at all. After cleaning by following the steps the steel rods was shining again. However, after turning on the car and driving it around the block multiple times, the engine light was still on, so I disconnected the battery for a couple minutes to reset the system as I didn’t have the device to reset it. Turned on the car and voila!, the engine light was off and the engine was literally running smoother and not sounding as heavy between shifting gears. A potentially $550 repair, cost me $20. Thanks once again, much appreciated!!!!

Worked beautifully on my Mazda, I mean scion ia ;). Mine wasn’t even dirty per se, but all of the ash my little ia has probably been breathing in the last 12 months probably made it worse. Went from hiccup-like noises on idle to a smooth purr in 15 minutes

[@5MinuteFixit]

That’s great! I’m glad it was helpful and you got the smooth purr result. Thank you for watching and please consider giving the video a thumbs up if you haven’t already! Thank you!

[@svtirefire]

The part you cleaned is the IAT, not the MAF. They are integrated into one part. The MAF is up inside that hole at the tip.

I took my car to autozone to see why my check engine light was on, they said i need a mass air flow sensor. if i do this and it works, will it make my check engine light go off?

[@elvismanrocks]

Another nice video!

[@tehxii7706]

Would this help if my 2009 100k 2.0l struggles up hills but is better when I put fuel injector cleaner in it?

[@5MinuteFixit]

I would do both, they are both relatively cheap to do and if that doesn’t seem to help dig a little deeper. Thank you for watching!

[@miscellaneousstuff2901]

I wonder if acetone would work? Basically you just need a solvent that will remove the grime but not damage the maf sensor. Acetone is pretty good at that. Anyone know?

[@certifiedhero7]

So don't touch the wires with your finger or the nozzle.... but spray liberally?

[@5MinuteFixit]

Certified Hero don’t touch the wires with your fingers or with the nozzle but get the nozzle as close as possible and spray liberally. Thanks for watching!

[@flyingcowking]

Keep your finger oils off is why

[@dragoniousmaximus7304]

Sooo. My Mazda 3 2010 is idling rough and when I unplug the sensor it runs fine. Itvwas doing the same thing 8 months ago and I cleaned it like you did and it ran until yesterday then it started doing it again. I cleaned it again bit it hasn't fixed the problem. Do you think I just need a new maf sensor?

[@5MinuteFixit]

Does it only idle roughly when the engine is cold?

[@dragoniousmaximus7304]

@@5MinuteFixit no. It idles like that after 10 min of driving also. I live in Hawaii so it's always hot here. When I unplug the MAF sensor when it is running it runs fine...

@@dragoniousmaximus7304 I would think it’s the sensor going bad then... let me know if you end up changing it and how it works out. Thanks again for watching!

its kind of hard to see but is the tip of the sensitive part suppose to be look like an amber drop? or does that mean its burnt out?

[@jwhit4075]

@@5MinuteFixit can you do the throttle body cleaner video too?

[@5MinuteFixit]

Hopefully this will fix your issue…sometimes you may have to drive a bit to clear the code after you’ve cleaned the sensor.

[@josesapad9138]

hello sir,can i use contact cleaner or penetrating oil for that in reason that i dont have one from CRC?

[@5MinuteFixit]

I would try to use a dedicated MAF cleaner but I believe contact cleaner is very close.

[@marialudwig7863]

I cannot for the life of me get the tab to de-attach from the sensor. Does it matter if it stays connected?

[@OmniNature]

Sorry just seen this video but yes it does matter. Just make sure you push hard enough and pull it apart with force but gently. It will come off.

[@mr2cqql]

I got code p2187 comes on and off on my 06 2.3L, do you think the maf sensor needs cleaning?

[@5MinuteFixit]

I would definitely start there, it’s very easy to clean the MAF sensor so it wouldn’t hurt to try and that could very well be the issue. Keep in mind that Sometimes you have to drive a set number of miles before the light turns off. Thank you for watching, hopefully this helps!

[@historiamotoryzacji1558]

Why I can't touch maf?

[@5MinuteFixit]

You don’t want to touch the small wires/blades inside the MAF housing the oil on your hands could affect the reading.

[@grayprojects591]

Just did this and now my AFR is high af. My MAF is fucked and literally just spent 300 to get new one, don't do this lol

[@bulldozer99]

What about using a carb cleaner instead, would that work?

[@5MinuteFixit]

I would stick with the MAF cleaner if possible only because there are sometimes sensitive electronics that can be damaged. Hopefully this helps, thank you for watching.

[@242-f5u]

As the previous post says, just go with the Mass Air Flow Sensor cleaner from CRC. Any auto parts store will have it. It's maybe $10 and will last you a very long time. Once you have this, you can periodically clean the sensor at any time. It's very easy to do, yet mechanics will attempt to charge you up to $800 to replace the sensor altogether. Even if it needs to be completely replaced, you usually can find an original mass air flow sensor (OEM part) for $100 or so, instead of paying what a mechanic will charge for an incredibly easy job. It literally takes less than five minutes to do.
