Mazda 3 mass air flow sensor problems.
A faulty maf sensor can cause your vehicle to run too rich or run too lean.
As a result the engine either halts or idles roughly.
Unplug the wire harness.
Quick test to tell if mass air flow sensor is bad or dirty which could be causing your car or truck to run bad or keep cutting off.

We will cover exactly what that means and potential fixes for it below.
With the mazda 3 p0101 means the the mass air flow maf sensor has a range performance problem.
These are the bad maf sensor symptoms that indicate that the sensor is completely out of order.
