The MAF sensor measures the mass of air entering the intake and helps the engine control unit calculate the proper fuel amount for efficient combustion. Over time, factory sensors can accumulate dirt and oil, potentially causing rough idle, hesitation, or a Check Engine Light. This AA Ignition replacement is designed to fit like the factory part and deliver consistent signals to the PCM.\u003c\/p\u003e\n\u003cp\u003eDirect fit and easy installation: This unit is designed as a direct replacement for select GM vehicles and should mount where the original part sits.
