Your car, truck, or SUV has many small, but important sensors. The mass airflow or MAF sensor - measures the amount of air entering the engine. Your engine needs a precise amount of air & fuel to perform properly. If your mass airflow sensor is not functioning correctly, the engine will not inject the correct amount of fuel, which can impact your fuel economy, acceleration, and overall power.
