Walker 245-1585 Mass Air Flow Sensor

Walker 245-1585 Mass Air Flow Sensor

Walker 245-1585 is a complete assembly mass air flow sensor built for precise airflow measurement and OE-style drivability. It is a direct replacement for select Volkswagen applications, including Atlas, Atlas Cross Sport, Crafter, Crafter Van, and Teramont models.

Complete Assembly Details

This Walker Complete Assembly line is designed for customers who want a sensor and housing assembly rather than a sensor-only service part. Walker builds these MAF sensors as 100% new units, with programmed and tested electronics, custom circuit boards, and flow characteristics tuned for the vehicle application. The result is a replacement part engineered to match the airflow calibration expected by the engine management system.

Installation Notes and Tips

For Volkswagen Atlas, Atlas Cross Sport, Teramont, Crafter, and Crafter Van applications, verify the connector style, terminal count, and OEM reference before installation. Because this is a complete assembly, inspect the air tube and connector area for contamination and ensure the intake tract is clean before fitting the new unit. Walker 245-1585 is also referenced for OEM number 03N906461 and Standard Ignition MAS0491 applications.
