Where is the mass air maf sensor in a 2002 buick regal?

The mass air flow (MAF) sensor in a 2002 Buick Regal is located in the air intake duct, just before the throttle body. It is a cylindrical-shaped component with a wire mesh screen inside. The MAF sensor measures the amount of air flowing into the engine and sends a signal to the engine control unit (ECU) which then adjusts the fuel injection accordingly.
