• Black housing with rectangular female connector
• 6 blade terminals for the specified application
• Meets or exceeds original equipment manufacturing specifications

Detailed Description

Part number MAF10131 is designed for vehicles that rely on accurate air metering to maintain proper fuel delivery and drivability. Fitment includes 1996-2005 Ford applications such as F-150, Expedition, Excursion, and Super Duty models, plus select Lincoln, Mercury, and Jaguar vehicles. This part cross-references Hitachi Automotive (e.g., MAF0039, MAF0040) for the same application.

As part of WAI's Sensor Only line, MAF10131 is a replacement sensor built to OE-level specifications and intended to match the original connector style and terminal layout. The design supports a direct installation path for technicians replacing a worn or inaccurate mass air flow sensor on Ford F-150 and other listed vehicles.

What It Helps Address

• Rough idle caused by incorrect airflow readings
• Hesitation or poor throttle response
• Check engine lights related to MAF sensor performance
• Fuel trim issues from inaccurate air measurement
• Driveability problems tied to a failing sensor element

Installation Notes and Tips

Verify connector shape, terminal count, and application notes before installation. This part is listed as sensor only, and one fitment row notes a 90-degree sensor and terminal orientation for the 2005 Ford F-150. Confirm the vehicle's original sensor configuration against the fitment notes, especially on Ford trucks and vans with similar model-year overlap.

Quality Assurance

WAI states that this mass air flow sensor is manufactured to meet or exceed OE specifications and is backed by a limited lifetime warranty. The Sensor Only line uses precision-engineered construction and high-grade materials to support fit, performance, and service life.
