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.
Where is the mass air flow sensor.
The part costs from 89 to 380.
A mass air flow sensor maf is a sensor used to determine the mass flow rate of air entering a fuel injected internal combustion engine.
It is intended to be insensitive to the density of the air.
The mass air flow sensor can also get dirty if the engine air filter is not changed on time which results in the same symptoms as a failed sensor.
A faulty maf sensor can cause your vehicle to run too rich or run too lean.
A replacement mass air flow sensor can cost anywhere from 20 to 600.
If the air flow sensor is bad it needs to be replaced.
In automotive applications air density varies with the ambient.
The air mass information is necessary for the ecu to correctly balance and deliver the correct amount of fuel to the engine.
Your car has a lot of sensors and this is just one that helps your car run properly.
Based on this data the ecu directs the fuel injection system to achieve the ideal air fuel mixture as demanded.
A mass air flow maf sensor responds to the amount of air flowing through a chamber containing the sensor.
It s a fairly simple job.
When a vehicle s mass airflow sensor is faulty or defective it can cause a variety of problems and usually results.
Your mass air flow sensor maf sensor is a piece of technology within your engine which tells your car s computer how much air is entering the engine.
Air flow sensor replacement.
This is important as it allows your engine to regulate its performance and change the intake of air to keep your engine running in its best condition.
If you are going to replace the maf yourself then i d always recommend buying an oem mass air flow sensor.
The mass air flow sensor must be cleaned and the air filter must be reinstalled correctly or replaced.
It then sends the data to the engine control unit ecu.
Replacing a mass air flow sensor is fairly straight forward so most of the cost comes from the cost of the part and not the labor.
The air mass information is necessary for the engine control unit ecu to balance and deliver the correct fuel mass to the engine.
Air changes its density with temperature and pressure.
The sensor for volume consumption of air is used in many systems for management of engines for measuring value of the transitory cost of air.
If a sensor is dirty your mechanic may suggest cleaning it cleaning the airflow sensor is a.
What is a mass air flow sensor.
The mass air flow sensor monitors the volume and density of air entering the engine through the intake.
That brings up the question of can your car run without the mass air flow sensor.
The most common signs of a failing mass air flow sensor are poor engine performance such as hesitation or stalling.
