Product Details

Walker 245-1584 is part of Walker Products’ Sensor Only program, which focuses on replacement MAF sensors rather than complete housing assemblies. The design uses custom-engineered circuitry and calibrated flow characteristics to match the vehicle’s airflow measurement needs across the operating range. Walker states that many of its MAF sensors are manufactured in the USA using OEM-quality components and are verified through production and on-vehicle testing. This part cross-references Standard Ignition MAS0488 for the same application.

Common Problems This Part Can Address

  • Rough idle caused by inaccurate airflow readings
  • Check engine light related to mass air flow sensor performance
  • Hesitation or poor throttle response during acceleration
  • Fuel trim issues from a contaminated or failing MAF sensor
  • Driveability problems on Honda Civic and Honda Clarity models

Installation Notes and Tips

Before installation, inspect the air inlet tract and connector area for dirt, oil, or damage. Because this is a sensor-only replacement, transfer only the needed components and avoid touching the sensing element with bare hands. Confirm the connector shape, terminal count, and mounting style match the original unit before installation on your Honda Civic or Honda Clarity.

Walker Products has supplied fuel system components since 1946 and is an ISO 9001 / IATF 16949 certified manufacturer. Walker 245-1584 is 100% new, programmed, and tested for fit, form, and function before sale.
