How To Buy a Mass Air Flow Sensor
A failed mass air flow (MAF) sensor can put a hole in your pocket due to your vehicle's overconsumption of fuel. Understanding what your MAF sensor does can help you know its importance and in turn, make you inspect the problem sooner, if you notice any failure symptoms. We make it easy at Buy Auto Parts to find the right replacement mass air flow sensor for your vehicle. This buyer's guide helps you in learning the basic functionality and answers the questions you may have when purchasing a MAF sensor.
What does a mass air flow sensor do?
The mass air flow (MAF) sensor is an electronic sensor that helps in determining the amount/mass of air flowing into the engine. It sends the value of the mass of air measured to the Engine Control Unit (ECU). The ECU then regulates the amount of fuel injected into the engine to prevent the engine from running rich or lean. The MAF sensor is responsible for maintaining the perfect air-fuel ratio, thereby ensuring optimal efficiency of the engine. The mass air flow sensor's readings are combined with readings from other sources such as the oxygen sensor to efficiently maintain the perfect air-fuel ratio.

Finding Your MAF sensor's OEM Part Number | |||
If for any reason you cannot find your mass air flow sensor by entering your vehicle's year, make and model, you can find the best MAF sensor for your vehicle by its Original Equipment Manufacturer (OEM) number. The OEM part number can be found directly on the part itself. You can also call a dealership with your VIN number, and they will provide you with the OEM part number. You can give one of our car specialists a call at 1-888-907-7225 for further assistance in purchasing your MAF sensor. | |||

Direct-Fit or Universal-Fit Direct-Fit Mass Air Flow Sensor: The name of this style is pretty self-explanatory. These mass air flow sensors are designed to precisely bolt onto your application without any additional modifications. Universal-Fit Mass Air Flow Sensor: The alternative to a direct-fit style is the universal-fit mass air flow sensor which does require some minor modifications. This style fits hundreds of applications but you still need to confirm your application before purchasing. This style is recommended if your vehicle already has a universal-fit MAF sensor in it or if you are looking for a more cost-effective option. | |||
Things to Include with your Purchase | |||
Air Filter
|
Don't forget to inspect your air filters while replacing the MAF sensors. An air filter is responsible for purifying the outside air and sending it to the engine. Since the mass air flow sensor is located between the air filter and the engine, a failed filter will cause damage to the sensor. While replacing the MAF sensor, it is often recommended to inspect the air filter and replace it, if required. | ||||||||||||||||||||
