diesel particulate filter (DPF) differential pressure sensor OEM number 2871960

The Diesel Particulate Filter (DPF) Differential Pressure Sensor – OEM 2871960 is an exhaust monitoring sensor used in diesel aftertreatment systems to measure pressure difference across the DPF.

It works by comparing exhaust pressure before and after the filter to determine soot loading and filter restriction. This data is sent to the engine control module (ECM), which uses it to manage DPF regeneration cycles, maintain emissions compliance, and protect engine performance.

Built for Cummins and other heavy-duty diesel applications, this OEM sensor is critical for accurate emissions control, helping prevent clogging, improve fuel efficiency, and ensure proper aftertreatment system operation.
