Product Details

HELLA Electronics has supplied OE-focused electronic components for decades, and this mass air flow sensor reflects that background with a direct replacement design for airflow metering. By measuring incoming air precisely, the sensor helps the engine computer adjust fueling more accurately, which supports drivability and consistent engine performance. This part cross-references Spectra Premium MA133S and Walker Products 245-1051 for the same application.

Fits 1993-1995 Ford Aerostar, N/A. Fits 1994 Mazda B3000, N/A. Fits 1994 Mazda B3000, N/A.

Common Issues This Part Can Address

• Rough or unstable idle caused by inaccurate airflow readings
• Poor throttle response during acceleration
• Reduced fuel economy from incorrect air-fuel calculation
• Check engine light related to mass air flow sensor performance
• Hesitation or drivability problems under load

Installation Notes and Tips

Verify connector count, mounting style, and suction pipe diameter before installation. This sensor uses a bolted mount and a 4-pin connector, so matching the original configuration is important for proper fitment on the listed Ford Aerostar and Mazda B3000 applications. Inspect the intake tract for contamination or air leaks before replacing the sensor, since those conditions can affect airflow readings.

Quality Assurance

HELLA is known for OE-oriented electronics and sensor manufacturing, and this part is built to deliver accurate airflow data for the specified applications. Confirm the stamped reference number and vehicle fitment details before installation.
