Detailed Product Overview
Standard Ignition MAS0138 is engineered to deliver precise airflow data to the ECU so the engine can maintain the correct air/fuel ratio for clean combustion and consistent drivability. The sensor uses a wear-free design with no moving parts, and its hybrid electronics are built to maintain dependable signal quality in hard engine conditions. This part cross-references Delphi AF10131 for the same application.
Compatible With 1999-2003 Ford F-150, 1999 Ford F-250, 1999 Ford F-250 Super Duty, 1999 Ford F-350, 1999 Ford F-350 Super Duty, 1999-2002 Lincoln Navigator, 2002 Lincoln Blackwood, and 1998-1999 Ford Taurus. If you are replacing a failing Ford F-150 mass air flow sensor or servicing a Lincoln Navigator airflow meter, MAS0138 provides the correct fitment profile for these listed vehicles.
Common Problems This Part Can Address
- Rough idle caused by inaccurate airflow readings
- Hesitation or stumble during acceleration
- Incorrect fuel trim from a faulty MAF signal
- Check engine light related to airflow sensor performance
- Poor drivability under load or at varying engine speeds
Installation Notes and Tips
Verify the connector shape, terminal count, and bolt-hole pattern before installation. This MAS0138 mass air flow sensor uses a bolt-on mounting style, a rectangular female connector, and a complete assembly layout with housing included. Inspect the intake tract for contamination or leaks before installing the new sensor, and confirm the electrical connector is clean and fully seated.
