Hitachi MAF0081 Mass Air Flow Sensor

Hitachi MAF0081 Mass Air Flow Sensor

Hitachi MAF0081 is a new mass air flow sensor built for accurate air measurement and stable engine management. It is a direct-fit emission control sensor for select Chevrolet Express, Silverado, GMC Savana, and Sierra applications, including 2001-2007 Chevrolet Silverado 2500 HD and GMC Sierra 2500 HD models.

Key Features

• Measures incoming air volume and air characteristics for precise fuel control
• New Hitachi sensor with precision elements and high-quality components
• 100% air flow tested for application-specific performance
• Calibrated for each vehicle application to support factory emission standards
• Protected circuitry for added durability in daily driving conditions
• Wiring harness not included

Detailed Description

The Hitachi MAF0081 mass air flow sensor is engineered for vehicles that rely on accurate airflow data to manage fuel delivery, idle quality, and emissions performance. Hitachi uses precision sensing elements and application calibration to help maintain OE-style operation on compatible Chevrolet Silverado 2500 HD, Chevrolet Silverado 3500, GMC Sierra 2500 HD, and GMC Sierra 3500 trucks, as well as Express and Savana vans. This part cross-references Standard Ignition MAS0280 and Delphi AF10146 for the same application. If you are replacing a failing MAF sensor on a 2001-2006 Chevrolet Silverado 2500 HD or a 2006-2007 GMC Savana 3500, MAF0081 provides a direct replacement path with OE-focused construction.

Common Problems This Sensor Can Help Address

• Rough idle caused by inaccurate airflow readings
• Hesitation or poor throttle response during acceleration
• Check engine light related to mass air flow sensor faults
• Reduced fuel economy from incorrect air-fuel calculations
• Emission test failures tied to airflow measurement errors

Installation Notes and Tips

Verify connector style, terminal count, and housing configuration before installation. This sensor uses a 5-terminal blade connection and does not include a wiring harness or housing. Inspect the intake tract for dirt, oil contamination, or air leaks before installing the new sensor, and clear diagnostic trouble codes after replacement. Confirm vehicle application by year, make, and model before ordering.

Quality Assurance

Hitachi manufactures this sensor as a new OE-style replacement with 100% air flow testing and protected circuitry. Application-specific calibration helps support accurate airflow measurement and factory emission requirements on listed Chevrolet and GMC vehicles.
