Hitachi MAF0099 Mass Air Flow Sensor

Hitachi MAF0099 Mass Air Flow Sensor

Restore accurate air measurement with the Hitachi MAF0099 mass air flow sensor. Built for OE-style performance, this sensor is calibrated for specific applications and uses precision elements to help maintain proper engine airflow readings on select Infiniti and Nissan models.

Compatible with 2002-2004 Infiniti I35, 2003 Infiniti G35, and 2002-2003 Nissan Maxima applications, the Hitachi MAF0099 is a direct-fit emission control sensor for vehicles that require reliable airflow data for engine management.

Key Features

• Mass air flow sensor for emission control and engine air measurement
• Precision sensing elements for accurate airflow readings
• Application-specific calibration for OE-style operation
• Protected circuitry for added durability and stable signal output
• Housing included for the listed applications
• 5-terminal blade connector design

Detailed Description

The Hitachi MAF0099 measures the amount and characteristics of air entering the engine so the control system can manage fuel delivery and emissions more precisely. It is engineered for select Infiniti I35, Infiniti G35, and Nissan Maxima models, including 2002-2004 Infiniti I35, 2003 Infiniti G35 to 06/2003, and 2002-2003 Nissan Maxima. This part number, MAF0099, is calibrated for each application and 100% air flow tested to support consistent performance.

This part cross-references Delphi AF10216 and Standard Ignition MAS0153 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 control from incorrect air measurement
• Hesitation or drivability issues tied to sensor signal errors
• Emission test failures caused by improper air-fuel management

Installation Notes and Tips

Verify connector style, terminal count, and housing configuration before installation. This Hitachi MAF0099 uses a 5-terminal blade connection and includes housing for the listed applications. Confirm the vehicle build date where noted, since some fitments apply only through or from specific production months.

Quality Assurance

Hitachi manufactures this mass air flow sensor with precision components, protected circuitry, and application-specific calibration to support OE-level fitment and signal accuracy. The design is approved for OE manufacturer applications and tested for airflow performance before release.
