A mass air flow sensor MAF is used to measure the air flow that enters the engine at any given RPM range and is monitored by the vehicles computer to make adjustments to the fuel delivery and ignition timing. With the engine at idle the MAFs PID value should read anywhere from 2 to 7 gramssecond gs at idle and rise to between 15 to 25 gs at 2500 rpm depending on engine size.
Here is a fast and accurate way to track a MAFs performance and output to the PCM.
What is a mass airflow sensor. 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. A Mass Air Flow sensor MAF is one of the key components of an electronic fuel injection system in your car. It is installed between the air filter and the intake manifold of the engine.
Mounted in the air intake duct or air filter housing a sensor detects the air density as it heads into the engine intake to be mixed with fuel. The mass air flow MAF sensor part of your vehicles electronic fuel injection system is responsible for calculating the total amount of air entering the engine. The sensor used to determine mass flow rate of the air is known as mass airflow sensor.
Mass Airflow Sensors MAF have the responsibility of reporting the amount of air entering the engine to the Powertrain Control Module PCM. The Mass Air Flow Sensor also known as the MAF is one of the main electronic components of the fuel delivery system. The mass air flow sensor measures the air mass flowing into the engine intake.
Common mass air flow sensors have a very simple design. The sensor has two wires inside of which one is heated and the other left cold. The MAF system measures air through a unique method.
A mass airflow sensor MAS determines the mass of air entering a vehicles fuel injection engine and passes that data to the Engine Control Unit or ECU. The air mass. Mass airflow sensors or MAF sensors for short measure the density of the air passing through an engines intake and report to the ECU engine control unit computer allowing it to deliver the right amount of fuel through the injectors and into the combustion chambers.
The mass air flow MAF sensor measures the volume and density of the air entering the engine. Furthermore the mass air flow MAF sensor also measures the temperature of the incoming air. The mass air flow MAF sensor is always located in the air stream before the throttle body.
Your Mass Air Flow Sensor MAF Sensor is a piece of technology within your engine which tells your cars computer how much air is entering the engine. 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. The mass airflow sensor is a key sensor in your car.
Your car has a lot of sensors and this is just one that helps your car run properly. That brings up the question of can your car run without the mass air flow sensor. In this article we will look at what happens when you disconnect the mass airflow sensor.

A mass air flow sensor MAF is used to measure the air flow that enters the engine at any given RPM range and is monitored by the vehicles computer to make adjustments to the fuel delivery and ignition timing. A MAF mass air flow sensor measures the volume of air passing through the air tube to indicate engine load.
There are several types found on vehicles today. These include the cold wire hot wire Karmen Vortex and the vane type MAF sensors. The vane type MAF sensor uses a paddle or door that moves as air rushes by.
Its always a good idea to test a Mass Airflow MAF sensor before replacing it. Here is a fast and accurate way to track a MAFs performance and output to the PCM. Connect a scan tool to see the MAF sensor Parameter Identification Data PID information.
With the engine at idle the MAFs PID value should read anywhere from 2 to 7 gramssecond gs at idle and rise to between 15 to 25 gs at 2500 rpm depending on engine size.
