Fitment Level: OE Match / Platform Verified

Compatible with heavy-duty diesel emission aftertreatment systems using OEM references:

• 5461550
• A056N688
• 0281007173
• 0281007174
• 5461550RX (aftermarket interchangeable listing code)
• A056N699 / A056N715 (related PM sensor family variants depending on calibration)

Typical applications include:

• DAF CF Euro 6 (MX-11 / MX-13 engines)
• DAF XF Euro 6 (MX engine platforms)
• Select Cummins EPA17 / Euro 6 heavy-duty diesel emission systems
• Class 8 / heavy truck DPF downstream soot monitoring systems

This sensor is used in diesel particulate matter monitoring systems, where it measures soot concentration after the diesel particulate filter (DPF). The ECU uses this data to evaluate filter efficiency, control regeneration cycles, and detect abnormal particulate breakthrough conditions in real time.

⚠️ Important:
This is a DPF particulate matter (PM) sensor, not a NOx or pressure sensor.
It directly measures soot concentration downstream of the DPF and is essential for regeneration control, emissions compliance, and diagnostic fault detection.

Fitment must always be confirmed strictly by OEM numbers (5461550 / A056N688 / 0281007173 / 0281007174), as this Bosch sensor family is widely shared across DAF and Cummins heavy-duty platforms.
