Cummins 4984928 Mass Flow Sensor Assembly

The Cummins 4984928 is a mass flow sensor designed for monitoring exhaust gas recirculation (EGR) and intake air mass flow in heavy-duty diesel and natural gas engines. It provides critical data to the engine control module (ECM) for optimizing combustion efficiency and meeting emission standards. This sensor is engineered for high-temperature exhaust environments and vibration resistance typical in construction machinery and commercial truck applications. It serves as a direct OEM replacement for Cummins C-series, ISC, QSC 8.3L, QSL 8.9L, and ISL G engine platforms. The sensor housing is constructed from high-temperature resistant aluminum alloy with integrated electrical connector.
