Hitachi MAF0123 Mass Air Flow Sensor

Hitachi MAF0123 Mass Air Flow Sensor

Hitachi MAF0123 is a mass air flow sensor for select Nissan and INFINITI applications. It measures the volume and characteristics of incoming air so the engine control system can maintain accurate fuel delivery and emissions control.

Built with precision sensing elements and protected circuitry, this Hitachi air flow sensor is calibrated for each application and tested for airflow performance before release.

Key Features

• Mass air flow sensor for emission control systems
• Application-calibrated for accurate air measurement
• Precision elements and quality components for durability
• Protected circuitry for reliable operation
• 100% airflow tested for performance verification
• OE-approved design for direct replacement use

Detailed Description

The Hitachi MAF0123 is engineered to monitor intake air entering the engine and send the data needed for proper fuel management. This helps the vehicle maintain the air-fuel balance required for smooth operation and emissions compliance. It is a direct-fit replacement for select Nissan Altima, Maxima, Murano, Pathfinder, Quest, Rogue, X-Trail, and INFINITI QX60 applications, including 2014-2020 model years listed in the fitment data. This part cross-references Standard Ignition MAS0467 for the same application.

What It Helps Address

• Rough idle caused by inaccurate airflow readings
• Check engine light related to mass air flow sensor faults
• Poor fuel economy from incorrect air-fuel calculation
• Hesitation or sluggish throttle response
• Emissions test failures tied to intake air measurement errors

Installation Notes and Tips

• Verify the connector style and terminal count against the vehicle listing before installation.
• Inspect the intake tract for leaks, contamination, or damaged wiring before replacing the sensor.
• Clear diagnostic trouble codes after installation and confirm live data readings.
• Use the exact year and model notes shown in the fitment data, including date-specific applications such as 2014-2016 Nissan X-Trail and 2016 INFINITI QX60.

Quality Assurance

Hitachi manufactures this sensor to OE-level standards with application-specific calibration and airflow testing. The design uses durable components and protected circuitry to support consistent performance in the listed Nissan and INFINITI applications.
