Standard Ignition MAS0118 Mass Air Flow Sensor

Mass Air Flow Sensor for Ford and Mazda Applications

The Standard Ignition MAS0118 is a complete mass air flow sensor assembly built for accurate airflow measurement and stable engine management. It is a direct-fit emission control sensor for select Ford, Mercury, and Mazda vehicles, including Ford Escape, Explorer, Ranger, Mustang, Taurus, Windstar, and related applications.

Key Features

• 100% new, never remanufactured construction
• Computer-tested for accurate airflow readings under demanding engine conditions
• Proprietary sensing elements for consistent output across a wide ambient temperature range
• Complete assembly with a rectangular female connector
• Plastic housing with 6 male pin terminals
• Built to strict quality standards for aftermarket replacement use

Detailed Description

Standard Ignition MAS0118 is a mass air flow sensor designed to report incoming air volume to the ECU so the engine can maintain the correct air/fuel ratio. Accurate airflow data is critical for clean combustion, smooth drivability, and proper fuel control. This unit is a complete assembly with a rectangular connector layout and is engineered for direct replacement in a range of Ford, Mercury, and Mazda platforms. It cross-references Beck/Arnley 158-1256 and Delphi AF10127 for the same application.

Compatible vehicle coverage includes 1999-2003 Ford Explorer, 2001-2007 Ford Escape, 2001-2004 Ford Mustang, 2001-2003 Ford Ranger, 2000-2003 Ford Taurus, 1999-2003 Ford Windstar, 1999-2003 Mercury Mountaineer, 2000-2003 Mercury Sable, and 2000-2006 Mazda MPV. The MAS0118 part number is also used across additional Ford E-Series and related applications listed in the fitment data.

Common Issues This Sensor May Resolve

• Rough idle caused by incorrect airflow readings
• Hesitation or poor throttle response during acceleration
• Check engine light related to mass air flow sensor performance
• Fuel trim problems from inaccurate air/fuel calculation
• Hard starting or unstable engine operation after sensor failure

Installation Notes and Tips

Before installation, verify connector shape, terminal count, and vehicle fitment against the existing sensor. Inspect the intake tract for dirt, oil contamination, or air leaks that can affect sensor readings. After installation, clear diagnostic trouble codes and confirm idle quality and airflow data with a scan tool if available.

Quality Assurance

Standard Ignition manufactures this sensor as a new replacement part and computer-tests each unit to confirm accurate signal output. The design uses proprietary sensing elements and production controls intended to maintain consistent performance across changing temperature conditions and engine loads.
