The sensor uses a programmable ceramic circuit board with premium silicon coating to help protect the electronics from under-hood heat swings and road vibration, while the platinum resistance thermometer sensor design supports quicker signal response and steady measurement output. This part cross-references Delphi AF10676 for the same application. If you are replacing a worn Mercedes-Benz Sprinter 2500 mass air flow sensor, Mercedes-Benz E250 MAF sensor, or Mercedes-Benz GLE300d airflow sensor, MA494 provides the correct OE-style service fitment.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Solve\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRough idle caused by inaccurate airflow readings\u003c\/li\u003e\n\u003cli\u003eCheck engine light related to mass air flow sensor performance\u003c\/li\u003e\n\u003cli\u003eHesitation or poor throttle response during acceleration\u003c\/li\u003e\n\u003cli\u003eFuel mixture issues from incorrect intake air measurement\u003c\/li\u003e\n\u003cli\u003eDriveability problems tied to a failing Mercedes-Benz diesel MAF sensor\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify connector shape, terminal count, and inlet\/outlet diameter before installation.
