Accurate airflow input is important for fuel delivery, idle quality, and overall drivability. This part cross-references Hitachi Automotive MAF0094 for the same application. Compatible vehicle coverage includes 2003 Nissan Pathfinder, 2002 INFINITI I35, and 2002 Nissan Maxima.

Common Issues This Part May Resolve

• Rough or unstable idle caused by incorrect airflow readings
• Hesitation during acceleration
• Poor fuel control from a failing mass air flow sensor
• Check engine light related to airflow sensor performance
• Reduced drivability from contaminated or worn sensor elements

Installation Notes and Tips

Verify connector style, terminal count, and housing configuration before installation. The 5-terminal female connector and included housing should match the original setup on the vehicle. After installation, clear diagnostic trouble codes and confirm idle quality and throttle response during a road test. For fitment-specific service, use the vehicle application data for 2003 Nissan Pathfinder, 2002 INFINITI I35, and 2002 Nissan Maxima.
