Product Details

Delphi AF10431 is engineered for vehicles that use a probe-only mass air flow sensor configuration. It is a direct-fit emission control sensor for the intake system, helping the engine control module measure incoming air so fuel delivery and drivability remain properly managed. This part cross-references Standard Ignition MAS0383 for the same application. The Delphi AF10431 also cross-references Cardone Reman 74-50066 for select applications.

Compatible With 2008-2010 Ford F-250 Super Duty, N/A, and 2008-2010 Ford F-350 Super Duty, N/A, when equipped with probe-only Mass Air Flow Sensors. Search terms such as Ford F-250 Super Duty mass air flow sensor probe, Ford F-350 Super Duty MAF sensor replacement, and Delphi AF10431 fit these applications.

Common Issues This Part Can Address

• Rough idle caused by inaccurate airflow readings
• Hesitation or poor throttle response
• Check engine light related to mass air flow sensor faults
• Incorrect air-fuel mixture from a failing sensor
• Driveability problems tied to contaminated or worn MAF sensing elements

Installation Notes and Tips

Verify that the vehicle uses a probe-only mass air flow sensor before ordering. Confirm the connector style, terminal count, and bolt-on mounting points match the original unit. Inspect the intake tract for dirt, oil residue, or air leaks before installing the new sensor, and follow the included instruction sheet during service. For best results, handle the sensing element carefully and avoid contamination during installation.

Quality Assurance

Delphi draws on more than a century of OE experience and long-standing supplier relationships with major automakers. That OE background is reflected in the design and construction of the AF10431 replacement sensor for service on Ford Super Duty applications.
