Hi to all, I'm struggling with this mass air flow sensor (P0101) code and i try a few solutions but it last only for 1-2 months and the check engine light on again,limp mode and no power. I have been to a few mecanics,even 2 times to the Nissan dealer and ..... What can be done,i change the sensor,change the air filter,erase and reset the car computer and ...... I don t know where to go or who can fix this problem once for all. Thanks for help and suggestions. My car is Infiniti Q50 -2.2 diesel one year 2016 and only 52000 miles. .
