Detailed Description

This Walker Mass Air Flow Assembly 245-1417 is a replacement mass air flow sensor assembly for 2003-2006 Porsche Cayenne models. Mass air flow sensors measure incoming air so the engine control module can calculate fuel delivery and maintain proper drivability. When the original sensor becomes contaminated or fails electrically, replacing it with the correct assembly helps restore accurate airflow readings and stable engine operation. This part cross-references Standard Ignition MAS0451 for the same application.

Common Issues This Part May Address

• Rough idle or unstable idle speed
• Hesitation during acceleration
• Check engine light related to airflow measurement
• Poor fuel control caused by inaccurate sensor readings
• Driveability concerns on 2003-2006 Porsche Cayenne models

Installation Notes and Tips

Verify connector style, terminal count, and housing configuration before installation. This assembly uses a female connector with 5 terminals and includes the housing; mounting hardware is not included. Inspect the intake tract for dirt, oil contamination, or air leaks before installing the new sensor, and clear diagnostic trouble codes after replacement if required.
