Can you clean a bad mass air flow sensor?
Can you clean a mass air flow sensor? We recommend that you clean your MAF sensor every time you change your air filter.

What does it mean when MAF sensor is low?
It means the the Mass Air Flow (MAF) circuit is low, and that it is not performing within its specified operating range. We will cover exactly what that means and potential fixes for it below. It should be considered a high priority to fix, as the MAF sensor not reading properly can really make an impact on the performance of the vehicle.
