Mass Air Flow Sensor Guides

Zero restrictions in hoarding air plus enough fuel flow, only with an air mass meter.
Automotive experts say that the amount of air-fuel mixture should always be right, but how do you really know if the mixture amount is right? Well, that's the reason your auto has the air mass meter. This metering device measures the mass of air flowing into the engine. Based on this measurement, the engine computer unit (ECU) bases its calculations as to the amount of fuel the injector will atomize into the intake valve. Turns out, an efficiently working air mass flow meter equals better MPG and fuel economy.
An air mass meter is a plastic tube mounted right after the air box and through which the filtered air freely flows. As the air passes through it, a sensor measures the air mass. Electrical wires attached to the meter then transmit the measurement to the ECU for calculation. This meter is crafted to last the life of a vehicle, but micro particulates seeping through, coming together with the filtered air, may build up in and around it over time and render it useless.
There are different air mass meters for different applications: vane meter, cold wire, membrane, and hotwire meter. Among these, only the last three directly measure the mass of air going into the engine. The vane meter measures air volume, temperature, and pressure to determine density. Air mass is then calculated from the result. Whichever air mass meter is mounted in your auto, see to it that you keep it in shape for a long and reliable service.

Mass Air Flow Sensor Buyer's Guide

Summary

  • The mass airflow sensor works by measuring the amount of air that flows into the engine and reports it to the Engine Control Unit (ECU).
  • The common types of mass air flow sensors are: Moving Vane Meter, Hot Wire MAF Sensor, Cold Wire MAF Sensor. 
  • A mass air flow sensor usually costs $180-$284. Parts are usually sold individually. Brands offer different variants when it comes to design and packaging. Make sure to choose one that is the right fit for your vehicle type. 
  • A faulty mass air flow sensor decreases fuel efficiency. Have your vehicle checked if the check engine light illuminates.

 

In order to keep a car running at its best, it is important to make sure that the engine is in good condition. One of the key components to make this happen is the mass air flow sensor or MAF. These sensors are installed in fuel injected engines to ensure an efficient combustion process.  

 

How does a Mass Air Flow Sensor work? 

The car’s intake system is an integral part of the engine’s health. The MAF works by measuring the amount of air that flows into the engine and reports it to the Engine Control Unit (ECU). This sensor gets accurate information on the air’s mass, temperature, and pressure. By doing this, the ECU can control the amount of fuel injected into the engine’s combustion chambers.

 

It is important to monitor the amount of air flowing into the engine because it can constantly change due to external factors such as temperature and altitude. Airflow also change if you have engine enhancers such as turbochargers. 

 

A mass air flow sensor is installed in the intake manifold between the air filter and throttle valve. The MAF can be classified into three types:

 

Moving Vane Meter

This type of mass air flow sensor can be found in older fuel injected engines. Moving vane meters contain a door or a flap. This door pushes open depending on the amount of air that passes through the engine. It measures air density by how much the door is opened due to the air intake and sends this information to the ECU through electric signals. The ECU, in‌ ‌turn,  adjusts the fuel delivered according to this information. 

 

Although this design is simple and uncomplicated, it has its drawbacks. Moving vane meters can limit the amount of engine power because its design can restrict airflow. It can also be difficult to install and find a place to mount this kind of sensor in a tightly-packed engine bay. 

 
Hot Wire MAF Sensor

This newer type of mass air flow sensor is more accurate than a moving vane meter. Commonly located between the air filter and the throttle valve, it uses platinum wires to measure air density. As the platinum wire increases intemperature, so does its electric resistance. As the air flows through the engine, the wire becomes cooler which also lowers its electric resistance. The difference in resistance will determine the data sent to the ECU.

 

One of the advantages of using this type of mass air flow sensor is that it comes in a smaller package compared to moving vane meters.  This makes finding a place to mount it easier. The sensor does not restrict airflow because it only relies on a wire. Because it has no moving parts, it will not fail easily. 

 

If there is a drawback in having this kind of mass air flow sensor installed, it is the fragility of the platinum wire. Dirt and oil can easily damage the wire. Platinum wires can also be damaged if handled incorrectly. 

 

Another variant  that falls under this type is the hot-film MAF sensor. It works just like the hot wire MAF sensor but it uses sensor plates instead of wire. 

 
Cold Wire MAF Sensors

This type of sensor works just like the hot wire variant. The only difference is that it uses a second wire that is usually cold. The data from the hot wire is compared to the data from the cold wire. This gives a more accurate result in terms of air density. 

 

What are the things to consider in choosing a MAF replacement?

It’s important to consider your engine’s structure in choosing a MAF sensor. This will determine the right type of MAF sensor for your vehicle. It’s best to consult your trusted mechanic and have him recommend one for you. 

 

A mass air flow sensor usually costs $180 to $284 and are sold individually. Brands offer different variants when it comes to design and packaging. Make sure to choose one that is the right fit for your vehicle. 

 

Why is it important to have a faulty mass air flow sensor replaced? 

Having a faulty mass air flow sensor will decrease fuel efficiency. If the MAF is not working properly, it might send the wrong signal to the ECU, causing excessive fuel consumption. Your car will also burn more fuel even when idling. If you notice that you’re filling up your fuel tank more often than usual, it might be time to have your engine checked. 

 

Fortunately, most cars have a check engine light that illuminates when something is wrong with your sensor and engine. It is best to have your vehicle checked as soon as the warning signal appears to avoid other issues with your car. 

Important Facts You Need to Know About Mass Air Flow Sensor

Better fuel combustion is just a click away/ Install only quality Mass Air Flow Sensor, Mass Air Flow Sensor Plug, and replacement Mass Airflow Sensor.
The 1980s may have given us a lot of things to cringe about. There's the introduction of new wave music, weird hairdos, and outrageous fashion statements. However, the decade did provide us with something to smile about when the fuel injection system officially replaced carburetors. As a result, a number of components were developed to complement this system. One of these components is the Mass Air Flow Sensor.
This sensor is considered as an important part of your vehicle's electronic fuel injection system. It's installed in the intake air duct between the air filter and engine. This component measures and records how much air your fuel-injected engine is using. Once it's been able to collect the needed data, the mass air flow sensor plug then transmits it to your engine control unit or ECU. Using this information, the ECU proceeds to calculate the exact amount of fuel that will be injected into your engine's cylinders.
With the right amount of air, the engine can have superior performance. That's why you need a Mass Air Flow Sensor to calculate the right amount of air for your fuel-injected engine. This will enable your car to enhance combustion and reduce carbon emission. If you don't have this sensor yet, you can easily find a wide selection of mass air flow sensors for your car on the Web.

The Automobile Basics: Mass Air Flow Sensor

With the advent of fuel injection systems in modern times, vehicles are now outfitted with mass air flow sensors. A mass air flow sensor functions as a gauge which measures, true to its name, the amount of air which flows into your car's engine. It works hand in hand with the ECM. The ECM, which stands for Electronic Control Module, is the on board computer used by the car which is responsible for determining the metering of fuel and the timing of the injection as a response to parameters such as crankshaft position. As the mass air flow sensor takes the reading of the incoming air, it subsequently sends the gathered data to the ECM for it to provide a proper response. The end result is better performance from your car in the form of optimized fuel combustion as well as minimal emission. However, a malfunctioning mass air sensor can be very bad news for you. Such results of bad mass air sensors are poor acceleration, misfiring, and stalling during cases when the engine is cold among other things. To prevent such maladies from ailing your trusty ride, replace dysfunctional mass air flow sensors immediately with prime-grade quality replacements from CarParts. Check out our catalog now!

Mass Air Flow Sensor: Just the Facts

Your vehicle's engine can't make use of even the most expensive fuel without one basic element: air. For proper fuel combustion, the engine needs a mixture with the right amounts of air and fuel.And how do you make sure that the mixture sent to the engine's cylinders contains the ideal fuel–air ratio? Well, your best bet is to equip your vehicle with a reliable air mass meter. The air mass meter is a plastic tube usually mounted behind the air filter.The meter's interior contains sensors that determine how much air enters the engine bay. Attached to the meter are wires that relay the information to the vehicle's engine control unit (ECU), which in turn control fuel injection.Through information detected by the air mass meter, the ECU releases the right amount of fuel relative to the amount of air in the engine. See how helpful this meter can be? Should you want one for your vehicle, browse our catalogs.Various meters brands and designs are available here at Car Parts for you to choose from.
