The MAF Sensor: Keeping Your Engine’s "Breathing" Precise

The Mass Air Flow (MAF) sensor is the primary sensory organ for your engine"s fuel management system. Located between the air filter and the engine intake, it measures the volume and density of the air entering the combustion chamber. The Engine Control Unit (ECU) uses this data to calculate the exact amount of fuel to inject. Because this sensor sits directly in the path of incoming air, it is highly susceptible to contamination.
