The Cummins 5461550RX is a genuine OEM remanufactured Particulate Matter (PM) sensor designed for heavy-duty Cummins aftertreatment systems. This sensor monitors soot levels within the exhaust stream and plays a critical role in maintaining proper DPF performance and emissions compliance.

When a particulate sensor fails, it can trigger active fault codes, prevent proper regeneration, and cause engine derate conditions. Replacing a faulty sensor promptly restores accurate soot monitoring and helps prevent extended downtime.

This is a Cummins RX (remanufactured) unit and includes a $170 refundable core charge.
