Thank you so much for this video, you just saved me a lot of money! My 2017 Sentra SV had slipping gear issues (no check engine light though) around 100 kmh/65mph when under load and this seems to have fixed it completely. The engine runs remarkebly smoother and the gas mileage improved too. Will report back in some weeks when the next cold snap hits here in West Canada!

@@RBTheMechanic hmmm yeah this morning there was a terrible grinding noise in my brakes. So I took it to the dealership they checked it out said the rear drum brakes were dirty to clean them they wanted 115$ I declined and went on my way. Noise stopped everything was good. I took a 2 hour break then turned my car on to head towards work. When the traction light turns on and won't turn off that accompany the jerking rpms fluctuating. Took it back to the mechanic that cleared the P0101 code the first time and he said the ABS sensor was on something about losing signal and the mass air flow sensor code was still showing. So he recommended to change out the mass air flow sensor because he thinks thats what caused it. Mind you this is the first time this has ever happened

@@exsparkxelraz5569 well let’s see how it goes I had few that I had to send out for programming u prolly can find some local shop that dose that avoid dealer

[@LuisSilva-de9js]

Before you take off the sensor disconnect the negative terminal of the battery and let the sensor completely dry before you put it back in.

[@RBTheMechanic]

Luis Silva you can disconnect the battery but the problem is u will loose throttle memory and it will stall

[@kevinbazan6097]

Can i use any other spray to clean the sensor?

[@RBTheMechanic]

I wouldn’t recommend it use only MAF cleaner

[@lanway95]

Isopropyl alcohol works fine

[@avhv566]

Gracias me funciono bien 👍

How do I reset the light?

[@RBTheMechanic]

You can buy $40 scan tool from Autozone

[@briantate1614]

Can you reset the light by just disconnecting the battery?

[@RBTheMechanic]

Nooo noooo noooo alll these new Toyota’s with electrical throttle body u cannot disconnect the battery u will loose the memory and it will stall due to low rpm till it rebuilds memory which will take couple of drive cycles

[@edgarcampista9523]

I can't disconnect the sensor it's to hard to pull off! Any chance I can remove the 2 screws off or would that be wrong?

[@oscarcid5449]

You Have To Remove the 2 Screws for it to Come Off

Thank you very much for your video, I have a 2013 Nissan Altima s 4 cylinder. I cleaned the sensor just like you did. But the check engine light came back again, with the same code P0101. Do you have any other advice, please? Muchas Gracias 🙏

You don't have to wait for it to dry? Also, how do you reset the check engine light?

[@RBTheMechanic]

It will dry by the time ur finish installing or u can give it few more minutes u have to rest using scan tool

[@tomcaudill8681]

Very goog video but I am having problems unplugging wire harness.

[@RBTheMechanic]

Use flat heat or pick

[@pulgagutierrez2192]

What's happened if I don't have the diagnose computer take the black wire from battery

[@RBTheMechanic]

you will mess up the memory on the computer it will reset the light but your rpm might be low and car might stall so its better to go purchase cheap one good investment anyways

[@sourcreamsanchez6012]

My 2011 Sentra has the same code P0101 and hesitates when I push the gas. It can be a bit scary. I replaced the MAF sensor back in July. I got the part from Amazon for only $20. I guess I got what I paid for.

[@RBTheMechanic]

True replace it with better one let me n ow how it goes I had car one time I did some work took out the filter housing dust got on the sensor it was scary and hard to figure out what happned eventully we cleans it and it was like brand new

[@sourcreamsanchez6012]

I have a 2014 sentra. Will this trick work for my car? I bought the sensor for 169 bucks but I will return it if this trick works.

It works most of the time I would return it try this first if code comes back then I would replace it

My light came back on after cleaning it and after replacing it with a new one, wtf??

[@RBTheMechanic]

Yes that means issue with ECM prolly Ned software update

[@jonrogers3282]

That’s what the dealer told me today but you also need to change or make sure PCV valve is working properly, which in my case it wasn’t, so I changed it. Also, you need to clean the throttle body make sure the flaps don’t get stuck. And sure, it may need ecm reprogrammed but it is way too expensive. Maybe the engine can learn on its own after a while?

Hi thanks for your help.I disconnected the batterie before I replaced the mag sensor now my car stalled and I don't get a crank or dash board lights what should I do?

Well if u not getting crank that’s prolly starter u need to figure that out. And stall could be related to disconnecting the battery it looses memory and ur idle drops ... how did this happen did it stall and then it never cranked? Also scan the car for codes
