Standard Ignition MAS0140 Mass Air Flow Sensor

Mass Air Flow Sensor for Ford and Mazda Applications

The Standard Ignition MAS0140 mass air flow sensor is a sensor-only replacement built for accurate airflow measurement across a wide range of Ford, Lincoln, Mercury, and Mazda vehicles. It uses a bolt-on mounting style, a female oval connector, and a 6-pin male terminal layout for a direct-fit service replacement.

Standard Ignition MAS0140 is 100% new and computer-tested to help the engine control unit receive consistent airflow data under demanding engine conditions. That supports proper air/fuel ratio control for cleaner combustion in Ford F-150, Ford Explorer, Mazda CX-9, and other listed applications.

• Mass air flow sensor, sensor only
• Bolt-on attachment method
• Female oval connector with 1 connector and 6 male pin terminals
• Metal and plastic construction
• No housing included
• Hybrid electronic design with no moving parts for wear-free operation
• Cross-references Hitachi Automotive MAF0012 for the same application

Detailed Product Overview

This Standard Ignition MAS0140 mass air flow sensor measures incoming air so the engine computer can calculate fuel delivery accurately. By providing stable airflow readings, it helps maintain the correct air/fuel balance in vehicles such as the Ford Escape, Ford Fusion, Lincoln MKZ, Mazda Tribute, and Mercury Milan. The new, never-remanufactured design avoids leftover debris from prior use, while the electronic construction is built for consistent signal output.

Compatible With 2004-2010 Ford F-150, 2004-2012 Ford Explorer, 2007-2015 Ford Edge, 2007-2015 Lincoln MKX, and many other Ford, Lincoln, Mercury, and Mazda models listed in the fitment data. Part number MAS0140 is also referenced in aftermarket catalogs under related OE-style numbers for this application.

What This Sensor Helps Address

• Rough idle caused by inaccurate airflow readings
• Check engine light concerns related to mass air flow sensor performance
• Hesitation or poor throttle response from incorrect fuel metering
• Lean or rich running conditions tied to airflow signal errors
• Reduced drivability when the ECU cannot balance air and fuel correctly

Installation Notes and Tips

Install MAS0140 as a sensor-only replacement when the housing is being reused. Confirm the connector shape, terminal count, and bolt pattern before installation, and inspect the intake tract for contamination that could affect the new sensor. For best results, clear diagnostic trouble codes after installation and verify airflow data with a scan tool.
