It basically measures the amount of air entering the engine. It doesn't just guess, it calculates the mass of the air, which is different than volume, and sends that information to the engine’s computer. The computer then uses that data to figure out how much fuel to inject. It’s a pretty precise little device. Think of it as one of the key players in keeping your engine running smoothly. It works with the fuel injection system and the engine control unit. It’s constantly communicating so everything is balanced. Without a good reading from the MAF, the engine can’t properly adjust the fuel mixture. It's like trying to bake a cake without knowing how much flour you have. You’ll likely end up with something not quite right. A failing MAF sensor can cause a whole bunch of issues. You’ll notice if your engine is running rough, maybe idling poorly, or if the check engine light comes on. Fuel economy usually takes a hit too, since the engine isn't running efficiently. It can even affect how well your car accelerates. Basically, it keeps everything balanced for optimal performance and emissions. If you’re having engine problems, a bad MAF is often one of the first things we check. You can find a good replacement on sites like Fixparts Online, and there are a lot of videos online showing how to replace them if you’re handy. But if you’re not comfortable, it’s definitely a job for a mechanic. We’ve got you covered: Mass Air Flow Meter (MPN ADT374210) includes a 12-month warranty!
