As a result the engine either halts or idles roughly.
Mazda 3 mass air flow sensor problems.
The maf sensor is used to measure intake air volume for use in calculations to determine fuel and timing.
Engine idles roughly or halts.

The mass air flow maf sensor part of your vehicle s electronic fuel injection system is responsible for calculating the total amount of air entering the engine.
Locate the mass air flow sensor on your mazda 5 the sensor is located near the engine air filter housing.
In that case the car s computer cannot control the fuel to air ratio because the sensor does not send any information to it.
Next open the hood of your mazda.
These are the bad maf sensor symptoms that indicate that the sensor is completely out of order.
A completely failed maf sensor will not send any airflow information to the pcm.
Remove the screws that hold the mass air flow sensor in place.
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.
If the circuit has an issue replacing the sensor will not solve your problem.
With the mazda 3 p0101 means the the mass air flow maf sensor has a range performance problem.

Photo s show my 2005 mazda 3 2 3l but this generally applies to all models.
You ll notice if the tailpipes eject black smoke or when the engine runs rough or backfires.
We will cover exactly what that means and potential fixes for it below.
A maf sensor that behaves like this will require replacement.
Let the engine cool down.
Rough idle or stalls.
