Standard Ignition MAS0219 Mass Air Flow Sensor

Mass Air Flow Sensor for OE-Style Airflow Readings

Standard Ignition MAS0219 is a sensor-only mass air flow sensor built for direct replacement service on a wide range of Chevrolet, GMC, Hyundai, Kia, Buick, Cadillac, Pontiac, Saturn, and related applications. It uses a bolt-on design with a female oval connector and 5 blade terminals to deliver accurate airflow data to the ECU for proper air/fuel control.

Detailed Description

MAS0219 is engineered to provide the ECU with precise airflow readings so the engine can balance fuel delivery and maintain clean combustion. Standard Ignition manufactures this unit as a 100% new part rather than a remanufactured sensor, helping reduce the risk of leftover debris affecting sensor operation. For drivers servicing Chevrolet Express and GMC Savana vans, as well as select Hyundai Sonata, Kia Sorento, Buick LaCrosse, and other listed vehicles, this mass air flow sensor supports OE-style replacement where accurate airflow measurement is critical. This part cross-references Delphi AF10058 for the same application.

Common Issues It May Help Address

• Rough idle caused by inaccurate airflow signal input
• Hesitation or poor throttle response during acceleration
• Check engine light related to mass air flow sensor performance
• Incorrect air/fuel mixture from faulty airflow readings
• Driveability problems after sensor contamination or electrical failure

Installation Notes and Tips

• Confirm the connector shape, terminal count, and bolt-on mounting style before installation.
• Transfer only the sensor portion where the vehicle uses a separate housing assembly.
• Inspect the intake tract for leaks, dirt, or oil contamination that can affect airflow readings.
• Clear diagnostic trouble codes after installation and verify idle quality and throttle response.
• Use the vehicle-specific fitment list to confirm application details for Chevrolet Malibu, Buick Lucerne, Hyundai Genesis, and other listed models.

Quality Assurance

Standard Ignition tests this MAS0219 sensor electronically to verify accurate airflow output for ECU control. The part is manufactured to strict quality standards and built as a new replacement component for consistent service across the listed applications, including Chevrolet Express, GMC Savana, and Hyundai Sonata fitments.
