Standard Ignition MAS0202 Mass Air Flow Sensor

Mass Air Flow Sensor for GM Performance Applications

The Standard Ignition MAS0202 mass air flow sensor is a complete assembly built for accurate airflow measurement in GM performance and truck applications. It is a direct-fit replacement for select Chevrolet Camaro, Corvette, Express, Tahoe, GMC Savana, Pontiac Firebird, and Pontiac GTO models.

Key Features

• 100% new, never remanufactured construction
• Computer-tested for accurate airflow readings under demanding engine conditions
• Dual-heated sensing elements for stable performance across air/fuel systems
• Upgraded circuit components for improved reliability and ESD protection
• Thicker housing wall for added durability
• Plastic housing with bolt-on attachment, oval connector, and complete assembly design
• Female connector with 1 connector, 3 male blade terminals, and 2 bolt holes

Detailed Description

Standard Ignition MAS0202 is engineered to help the ECU receive precise airflow data so the engine can maintain the correct air/fuel ratio. That matters on vehicles such as the 1995-2002 Chevrolet Camaro, 1993-2002 Pontiac Firebird, and 1994-2000 Chevrolet Corvette, where accurate sensor input supports clean combustion and consistent drivability. The sensor uses high-quality sensing elements that hold up to supply-voltage changes and harsh operating temperatures from -40degF to 257degF. This part cross-references Delphi AF10056 for the same application.

What This Sensor Helps Address

• Rough idle caused by inaccurate airflow readings
• Hesitation or stumble during acceleration
• Check engine light concerns related to airflow sensor output
• Poor fuel control from incorrect air/fuel ratio data
• Driveability issues on GM Camaro, Firebird, Corvette, Express, Tahoe, Savana, and Pontiac GTO applications

Installation Notes and Tips

Install the MAS0202 as a bolt-on complete assembly and verify the connector style, terminal count, and housing shape before installation. Inspect the intake tract for leaks, contamination, or damaged wiring that could affect sensor readings. After installation, clear any stored diagnostic trouble codes and confirm idle quality and throttle response.

Quality Assurance

Standard Ignition manufactures this sensor to strict quality standards and computer-tests each unit to verify airflow signal accuracy before release. The upgraded internal components and reinforced housing are intended to improve circuit reliability and durability in demanding operating conditions.
