Located between the air filter and inlet manifold, the mass air flow sensor is one of the fundamental components of your vehicle's fuel-injection system. There are certainly several types of air mass meters that are created for different applications. Cold wire, hot wire or vane meter - whichever is mounted in your vehicle, you should keep it in shape for a reliable and long service. And we know how to help you.

    MAF sensor identifies the mass of air that enters through the intake and then sends that info to the engine computer (ECU), which calculates the amount of fuel that must be injected to the cylinders. And when the sensor is damaged, the computer is simply not able to ensure the right mixture. The basic principle behind the operation of all MAF sensors is the same. The only thing that differs is the way the sensor meters the air mass.

    The hot wire sensor is equipped with a heated filament. As the cool air rushes by, the filament cools down and its resistance changes so the current required to keep the temperature increases. The current increase is converted into voltage and sent to the ECU. The cold wire sensor defines the air mass using metal strips that vibrate when air goes through the meter. And it's the vibration frequency that is translated into the digital signal. Unlike the cold and hot wire sensors, the vane air meter measures pressure, volume and temperature of the air, then defines its density, and only then allows the ECU to calculate the air mass. Not that complicated, right? Well, however simple a MAF sensor seems to be, the issues are not that simple when it goes bad.

    The MAF sensor is engineered to last as long as you own your vehicle, but things happen and it may fail. And when the sensor doesn't react properly to the flow changes, you get a lot of problems. A damaged unit may cause the engine hiccup when throttle position suddenly changes. The vehicle may hesitate after starting or run excessively rich/lean. So what causes problems in the first place? When the air filter is installed in the wrong way or is just bad, it allows unfiltered air into the system, and the MAF sensor gets dirty. If you use an oiled air filter, it can cause troubles too. And because the cleaning process is quite tricky, it's not that hard to damage the unit.

    There are different ways to determine whether you mass air flow sensor went bad. For example, if your vehicle is running poorly and you believe it's because of the MAF sensor, you can unplug it. Should the engine run better when you do that, the MAF is most probably damaged. There is an easier way though. You can use an engine fault code reader. Anyway, if you see the CEL flashing and notice some of the symptoms of a bad MAF, don't procrastinate - take care of the problem. And when a replacement unit is needed, we'll be here for you.
