Detailed Description

The Delphi AF10442 is a mass air flow sensor engineered for vehicles that require a probe-only MAF sensor rather than a complete housing assembly. It measures incoming air so the engine control system can maintain proper fuel delivery, idle quality, and drivability. This part number AF10442 is listed for applications including 2007-2013 Mazda 3, 2007-2012 Mazda CX-7, 2004-2009 Subaru Legacy, 2004-2009 Subaru Outback, 2004-2008 Subaru Forester, and select Jaguar models such as XJ8, XKR, and S-Type.

This part cross-references Spectra Premium MA234 for the same application. It is also listed among interchange references used for select Cardone Reman applications.

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 probe-only MAF sensor
• Driveability issues on Subaru, Mazda, and Jaguar vehicles with the correct connector style

Installation Notes and Tips

Confirm the vehicle uses a probe-only mass air flow sensor before ordering. Verify the connector shape, terminal count, and mounting style against the original unit. This AF10442 uses a rectangular female connector with 5 male blade terminals and bolt-on mounting, so matching the OE connector layout is important for proper installation. Follow the included instruction sheet and inspect the intake tract for contamination or air leaks that could affect sensor readings.

Quality Assurance

Delphi builds aftermarket parts using OE experience and supplier knowledge developed over decades of original-equipment service. That OE heritage is reflected in the AF10442 design and application coverage for Subaru, Mazda, Jaguar, and Saab platforms.
