Detailed Description

Walker 245-1045 is a mass air flow sensor assembly engineered for specific Ford and Lincoln vehicles, including 1991-2000 Ford and Lincoln applications such as the Ford Mustang, Ford F-150, Ford E-Series vans, Ford Expedition, Lincoln Continental, Lincoln Mark VIII, and Lincoln Navigator. This assembly supports the airflow measurement needed by the engine control system to help maintain proper fuel delivery and drivability. The included housing and female 4-terminal connector make it a practical replacement for vehicles requiring a complete MAF assembly rather than a sensor-only service part. Walker Products manufactures engine management components with OEM-level specifications in mind, backed by ISO 9001/IATF16949 certified quality processes.

What It Helps Address

• Rough idle caused by inaccurate airflow readings
• Hesitation or stumble during acceleration
• Check engine light related to mass air flow sensor performance
• Poor fuel control from a failing MAF assembly
• Driveability issues on Ford and Lincoln engine management systems

Installation Notes and Tips

• Verify connector style, terminal count, and housing configuration before installation.
• Confirm vehicle application by year, make, and model, especially for Ford E-Series, Mustang, F-150, F-250, Expedition, Taurus, and Lincoln Continental listings.
• Inspect the intake tract for contamination, damaged wiring, or air leaks before replacing the sensor assembly.
• Use the part number 245-1045 to confirm catalog match and interchange references.
