Spectra MA252S Mass Air Flow Sensor

The Spectra MA252S mass air flow sensor is built for direct replacement on select Infiniti and Nissan applications. It uses a programmable ceramic circuit board with a premium silicon coating to help protect the sensor from under-hood heat swings and road vibration, while platinum resistance thermometer elements support quicker signal response and consistent airflow measurement.

  • Programmable ceramic circuit board for stable sensor operation
  • Premium silicon coating helps protect against heat and vibration
  • Platinum resistance thermometer sensors for faster signal response
  • Direct replacement for select Infiniti G20, Nissan Sentra, and Nissan NX applications
  • Part number MA252S for streamlined catalog lookup

Detailed Product Overview

As an emission control sensor, the Spectra MA252S measures incoming air so the engine control system can calculate fuel delivery more accurately. This matters on vehicles such as the 1991-1996 Infiniti G20, 1991-1994 Nissan Sentra, and 1991-1993 Nissan NX, where airflow data affects drivability, idle quality, and fuel management. This part cross-references Delphi AF10213 for the same application.

Common Issues This Sensor May Address

  • Rough idle caused by inaccurate airflow readings
  • Hesitation or stumble during acceleration
  • Check engine light related to mass air flow sensor faults
  • Poor fuel economy from incorrect air-fuel calculation
  • Hard starting or unstable engine performance

Installation Notes and Tips

Verify the connector style and application before installation. Inspect the intake tract, air filter housing, and wiring connector for contamination or damage, since debris or air leaks can affect sensor readings. After installation, clear diagnostic trouble codes and confirm idle and throttle response during a road test.

Quality Assurance

Spectra designs this sensor with materials and circuit construction intended to withstand demanding under-hood conditions. The MA252S is built as an OE-style replacement for select Infiniti and Nissan vehicles and is identified by part number MA252S for accurate ordering and fitment verification.
