Fitment Level: OE Match / Platform Verified

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

• 5461550
• 0281007173
• 0281007174 (paired revision in same Bosch PM sensor family)
• A056N688 / A054P722 (cross-reference Cummins/DAF catalog family)
• 4383978 / 4384375 (related aftermarket OEM-equivalent references)

Typical applications include heavy-duty diesel platforms such as:

• DAF CF Euro 6 (MX-11 / MX-13 engines)
• DAF XF Euro 6 (MX engine platforms)
• Cummins ISB / ISX emissions systems (platform-dependent configurations)
• Select North American Class 8 trucks using Bosch particulate matter sensor architecture (engine-dependent installations)

This sensor is used in diesel particulate matter (PM) monitoring systems, where it measures soot concentration downstream of the diesel particulate filter (DPF). The ECU uses this signal to evaluate DPF efficiency, optimize regeneration cycles, and detect abnormal soot breakthrough in heavy-duty emissions systems.

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

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