    "Mass Air Flow (MAF) sensors are used on some General Motors, Ford and import multiport fuel-injected engines to measure the volume of air entering the engine.

    This is necessary for the engine’s computer to calculate and maintain the proper air/fuel ratio for optimum performance and emissions. Other engines with “speed-density” fuel injection systems do not have a MAF sensor and use inputs from the throttle position sensor (TPS), manifold absolute pressure (MAP) sensor, incoming air temperature (IAT) sensor and engine rpm to estimate air flow."
