Causes and Fixes P0101 Code: Mass or Volume Air Flow "A" Circuit Range/performance 

very clear and to the point. Thanks

I have a 2018 nissan kicks and I have replaced the mass sensor 2 x in one year I had a friends obd2 tool mentioned gave the same error code but also mention the issue could be the altinator. I'm gonna see if my car has a vacuum leak next. Thanks l!

Hi. Thank you for the vid. I have a Vauxhall mokka (maybe Opel Mokka across the pond) I've had power/smoking issues for months now. If I need to put my foot down enough for the turbo to kick in (I know nothing about cars...) it will struggle really badly and start smoking from the exhaust really badly. So far, I've had the turbo replaced and it's since passed it's MOT... The issue is some what better, as it doesn't seem to try to stall anymore, but I'm not putting my foot down, as I'm avoiding motorways etc, so difficult to tell how bad the issue still is as I'm terrified of the pushing it and the engine blowing up!. My engine management light now keeps coming on and that's what's brought me to your vid after getting this error code. The car is currently not really fit for purpose.. I feel like this error code is now resulting from the initial problem... Does that make sense and could you possibly shed some light on what the fix could be. Thank you

Before or while changing expensive sensors... 1. Change air filter 2. Clean the throttle butterfly (for fords the idle air control solenoid also) Carbon/dirt deposits can cause the butterfly to not close completely letting in too much air at idle. YMMV

Hi Sir, when we are replace mass air flow sensor after that, we have to do the program again or just put a new one thank you

I got this code after I installed a cold air intake, could it be fixed still?

Hi I did everything on my 2021 Chevy Equinox check engine light still coming on not flashing just on and I am selling it to carmax end of this month my code reader says P1101 I changed the MAF sensor removed battery cables it drives like new but that light still on any ideas thank you kindly

Well, I replaced the mass air sensor and the p0010 is still on.

Can a bad o2 sensor cause that p101 code because I need a new one of those

Only thing you missed was a test for clogged converter

Hello I have a 2020 kia forte. I have code p0101. I replaced the air filter, mass air flow sensor, wiring has volts and looks good. The car runs fine after a few days the code returns. Any idea? Also when I unplug the sensor the car doesn't stall

Where is the MAF/waf sencor on a fiat Panda pop 2014

I did all that except the catalytic converter, i still got the code Wont go away , any solutions?

Hello Do you know if a bad turbo could cause p0101 codes? Reason I ask is because I have a Fiat 500 1.3 diesel and the car would start and cut out.. I diagnosed it to a bad Maf sensor due to the Maf not reading anything and when disconnected the car would run fine. I then bought a new MAF from ebay and although the car drives fine it throws an engine light after 15 or so miles with the code P0101. I suspect the turbo as the car does give out blue smoke on first start up and I do also feel as if the turbo doesn't kick in like it should (that may just be me expecting too much out of a 1.3😅) that's why I ask if the turbo could be the issue here any ideas?
