It reads the volume of incoming air so the engine control module can set correct fuel delivery; when a faulty MAF is the cause of drivability issues, replacing it with the correct part number and connector type can resolve error codes and rough-running conditions. Before installing, verify fitment against vehicle year and part references and clean the air box and filter to avoid false readings after replacement.\u003c\/p\u003e\n\n\u003ch3\u003eWhich vehicles and part numbers does this MAF sensor replace?\u003c\/h3\u003e\n\n\u003cp\u003eThis 6-pin MAF is specified to replace several OE numbers and fit multiple Ford and Lincoln applications across the mid-2000s.
