Hitachi MAF0046 is a direct-fit sensor for select Ford trucks and cars that rely on accurate airflow data for fuel delivery and emissions control. This part cross-references Delphi AF10154 for the same application.

Common Symptoms It Can Address

• Rough idle caused by incorrect airflow readings
• Hesitation or poor throttle response
• Check engine light related to air metering faults
• Reduced fuel economy from inaccurate fuel trim control
• Emissions test failures tied to faulty sensor output

Installation Notes

Confirm connector style and terminal count before installation; this unit lists 4 terminals for the covered applications. The wiring harness is not included, so reuse the existing harness or source the correct connector as needed. Verify the intake tract is clean before installing the new sensor to help protect the sensing element.

Quality Assurance

Hitachi builds this MAF sensor with precision elements, protected circuitry, and application-specific calibration. Each unit is air flow tested to support accurate readings and OE-level fitment on the listed Ford applications, including Ford F-150, Ford F-150 Heritage, and Ford Mustang.
