Typical applications include:

• Ram ProMaster 2.2 Multijet diesel (North America)
• Fiat Ducato 250 / 290 2.2 Multijet diesel (Euro 6)
• Fiat Ducato chassis cab / van configurations
• Opel / Vauxhall Movano B diesel (platform-shared systems)
• Nissan NV400 diesel (rebadged variants in some markets)

This sensor is used in diesel particulate matter monitoring systems, where it measures soot concentration downstream of the DPF. The ECU uses this signal to evaluate filter efficiency, manage regeneration cycles, and ensure emissions compliance across FCA light commercial diesel platforms.

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

Fitment must always be confirmed strictly by OEM number (46349778 / 0281008670 / 0281008671), as FCA uses multiple revisions across Ducato/ProMaster diesel platforms depending on emission calibration and model year.
