Bosch 0281002516 Mass Air Flow Sensor

The Bosch 0281002516 is a hot film mass air flow (HFM) sensor designed for diesel engine management systems. It utilizes a thin-film sensing element to measure mass air flow rate directly, providing a voltage signal proportional to air mass entering the intake manifold. The sensor operates on a 5V supply with a 0-5V analog output characteristic calibrated for Isuzu 4HK1 engine control modules. Constructed with a glass-fiber reinforced polyamide housing and gold-plated terminal pins for corrosion resistance. The sensing element is protected by a calibrated bypass channel and integrated intake air temperature compensation. Direct-fit replacement for Isuzu OE part numbers 8-97240-057-0 and 8972400570, compatible with Isuzu 600P and 700P series light-duty trucks equipped with 4HK1-TC engines. Interchanges with Wilminck Group WG1014208, WE Parts 330880043, Bremi 38732, and Fispa 38732 aftermarket references.
