What This Sensor Helps Address

• Rough idle caused by inaccurate airflow readings
• Hesitation or poor throttle response during acceleration
• Check engine light concerns related to airflow measurement
• Fuel trim issues from incorrect air-to-fuel calculations
• Driveability problems on Ford and Lincoln vehicles with MAF-related faults

Installation Notes

Verify the connector shape, terminal count, and mounting location before installation. Inspect the intake tract for dirt, oil residue, or air leaks that can affect sensor readings, and confirm the sensor is seated securely in the air intake assembly. For best results, clear diagnostic trouble codes and perform a relearn or idle adaptation procedure if required by the vehicle.
