Hitachi MAF0101 Mass Air Flow Sensor

Hitachi MAF0101 Mass Air Flow Sensor

Hitachi MAF0101 is a new mass air flow sensor for select Infiniti applications, including the FX45, M45, and Q45. It measures incoming air volume and airflow characteristics so the engine control system can maintain accurate fuel delivery and emissions performance.

• New Hitachi mass air flow sensor
• Measures air entering the engine for precise airflow reporting
• Precision sensing elements and quality components for durability
• 100% air flow tested for application-specific performance
• Calibrated for the listed Infiniti applications
• Protected circuitry and contaminant bypass port where applicable
• Wiring harness not included

Fitment Details

Compatible with 2003-2004 Infiniti FX45, N/A; 2003-2004 Infiniti M45, N/A; and 2002-2004 Infiniti Q45, N/A. This part cross-references Standard Ignition MAS0372 and TYC 7410132 for the same application.

What It Helps Address

• Rough idle caused by inaccurate airflow readings
• Hesitation or poor throttle response from incorrect air metering
• Check engine lights related to mass air flow sensor performance
• Fuel trim issues caused by contaminated or failing sensor output
• Emissions test failures tied to improper air measurement

Installation Notes

Verify connector style, terminal count, and housing configuration before installation. This Hitachi MAF0101 uses a blade terminal design with 5 terminals and includes the housing as listed for the confirmed applications. Inspect the intake tract for dirt, oil, or leaks that can affect sensor readings, and replace any damaged connector or harness components before final testing.

Quality Assurance

Hitachi builds this mass air flow sensor with OE-focused calibration and application testing to support accurate airflow measurement on the listed Infiniti vehicles. The design uses protected circuitry and durable components approved for OE-level use.
