Detailed Description

Standard Ignition MAS0478 is a direct-fit mass air flow sensor for select Volvo S60, S90, V60, V60 Cross Country, V90, V90 Cross Country, XC40, XC60, and XC90 models. It is used to measure incoming air volume so the engine control system can calculate fuel delivery and maintain proper drivability. This part cross-references Beck/Arnley 158-1813 and Delphi AF10672 for the same application.

What It Helps Address

• Rough idle caused by inaccurate airflow readings
• Hesitation or stumble during acceleration
• Check engine light related to airflow sensor performance
• Poor fuel mixture control from a failing MAF sensor
• Reduced throttle response on Volvo S60, S90, XC60, and XC90 models
