Fitment Level: OE Match / Platform Verified

Compatible with FCA diesel emission aftertreatment systems using OEM references:

• 68171189AC
• 68171189AA / 68171189AD (related revisions depending on year)
• 0281007482
• 0281007480
• Bosch PM sensor family 0 281 007 482 / 0 281 007 480

Typical applications include:

• Ram 1500 3.0 EcoDiesel (2014–2018)
• Jeep Grand Cherokee 3.0 EcoDiesel
• FCA VM Motori 3.0 diesel emission platforms

This sensor is used in diesel particulate matter monitoring systems, where it measures soot concentration downstream of the diesel particulate filter (DPF). The ECU uses this signal to:

• verify DPF regeneration efficiency
• detect soot breakthrough or filter degradation
• optimize regeneration intervals
• trigger diagnostic codes such as P24AE / P24AF when signal drift occurs

⚠️ Important:
This is a DPF particulate matter (PM) sensor, not a NOx or pressure sensor.
It directly measures soot concentration after the DPF and is critical for FCA EcoDiesel emissions control and regeneration logic.

Fitment must always be confirmed strictly by OEM number (68171189AC), as FCA frequently revises this sensor across model years and software updates.
