Spectra MA275 Mass Air Flow Sensor
The Spectra MA275 mass air flow sensor is built for direct replacement in select Nissan and INFINITI applications with an integrated housing. It uses a programmable ceramic circuit board with premium silicon coating to help protect the sensor from under-hood heat swings and vibration, while platinum resistance thermometer elements support quicker signal response and steady readings.
Key Features
- Mass air flow sensor with integrated housing
- Programmable ceramic circuit board construction
- Premium silicon coating for added protection against heat and vibration
- Platinum resistance thermometer sensor design for responsive signal output
- Direct-fit replacement for select Nissan Pathfinder and INFINITI QX4 applications
- Part number MA275 for catalog and cross-reference lookup
Detailed Description
Use the Spectra MA275 when replacing a failing air metering sensor on 1996-1997 Nissan Pathfinder and 1997 INFINITI QX4 models. Accurate airflow measurement is critical for fuel delivery, idle quality, and drivability, and this unit is engineered to restore consistent sensor output in vehicles equipped with an integrated housing. This part cross-references Hitachi Automotive MAF0024 for the same application.
Common Issues It May Resolve
- Rough idle or unstable engine speed
- Hesitation during acceleration
- Lean or rich air-fuel mixture readings
- Check engine light related to airflow sensor performance
- Poor throttle response on Nissan Pathfinder and INFINITI QX4 models
Installation Notes and Tips
Verify the connector style and housing configuration before installation. Clean surrounding intake components and inspect the air ducting for cracks, loose clamps, or contamination that can affect airflow readings. After installation, clear diagnostic trouble codes and confirm proper engine operation.
Quality Assurance
Spectra designs this sensor with heat-resistant circuit protection and responsive platinum sensing elements to support stable operation in demanding under-hood conditions. Part number MA275 is listed for 1996-1997 Nissan Pathfinder and 1997 INFINITI QX4 fitment.
