Hitachi MAF0031 Mass Air Flow Sensor

Hitachi MAF0031 Mass Air Flow Sensor

Hitachi MAF0031 is a new mass air flow sensor for select Nissan and INFINITI applications. It measures incoming air volume and airflow characteristics so the engine control system can maintain accurate fuel delivery and emissions control.

Key Features

• New Hitachi mass air flow sensor
• Precision sensing elements for accurate airflow measurement
• High-quality components for durability
• 100% air flow tested for application-specific performance
• Calibrated for each vehicle application
• Protected circuitry for reliable operation
• Wiring harness not included

Application Details

This Hitachi MAF0031 sensor is an OE-style replacement for a wide range of Nissan and INFINITI models, including the Nissan Armada, Titan, Titan XD, Frontier, Pathfinder, Murano, Maxima, Altima, 370Z, GT-R, and select INFINITI QX, Q, G, M, FX, and Q50/Q60 platforms. It is built to support accurate airflow readings on vehicles that use a blade terminal connection and, where noted, OE-style 5-terminal configurations. This part cross-references Delphi AF10141 and Standard Ignition MAS0208 for the same application.

What It Helps Address

• Rough idle caused by inaccurate airflow readings
• Check engine lights related to mass air flow sensor faults
• Poor fuel trim control from incorrect intake air measurement
• Hesitation or drivability issues during acceleration
• Emissions test failures tied to sensor performance

Installation Notes

Verify connector style, terminal count, and housing requirements before installation. Some listed applications use no housing and blade terminals, while others note specific build dates or package restrictions. Confirm the vehicle year, make, model, and notes against the fitment list before ordering. The wiring harness is not included, so reuse the existing harness where applicable.

Quality Assurance

Hitachi calibrates each MAF0031 sensor for its specific application and air flow tests every unit to support consistent performance. The design uses protected circuitry and OE-approved engineering practices to help maintain factory-level emissions control on covered Nissan and INFINITI vehicles.
