It basically measures the amount of air entering your engine. It doesn’t just guess, it’s pretty precise. It looks at the mass – how much actual weight of air is coming in, not just how much space it takes up. That information is sent to your engine’s computer, which then uses it to figure out how much fuel to inject. It's all about getting that air/fuel mix just right. Think of it as one of the key senses your engine relies on. The computer needs to know how much air is available so it can tell the fuel injectors what to do. It affects everything from idling to acceleration, and even overall fuel economy. It’s usually located somewhere in the intake system, between the air filter and the throttle body. Some vehicles have one, some have two. A failing MAF sensor throws everything off. You’ll notice if it’s going bad. Often it starts with a rough idle, maybe the engine feels a little sluggish when you hit the gas. You could get a check engine light, of course. Bad readings from the sensor mean the engine isn’t running efficiently, you’ll burn more fuel, and it could even cause damage to other parts down the line. A lot of times a simple replacement fixes these issues. We carry a good selection here, and you can also find them at places like Fixparts Online. It’s a pretty straightforward fix for a lot of common engine problems. Convenience at its best: Mass Air Flow Sensor (MPN 05L906461B) includes a 12-month warranty!
