What It Helps Address

• Rough idle caused by inaccurate airflow measurement
• Hesitation or stumble during acceleration
• Incorrect fuel delivery from a failing airflow sensor
• Check engine light conditions related to mass air flow sensor performance
• Poor drivability on Ford Ranger, Ford Explorer, and Mazda Navajo applications

Installation Notes

Verify the OE number and connector style before ordering, especially on Ford Ranger applications that reference OE # F07F12B579AA. Confirm the vehicle uses the listed 4-terminal female connector and compare the existing sensor configuration to the fitment notes. The housing is not included, so reuse or replace only the components required for your specific application.
