Fitment Level: OE Match / Platform Verified

Compatible with FCA diesel emission aftertreatment systems using OEM references:

• 68249512AC
• 0281006338
• 68249512AA / 68249512AB / 68249512AD (related revisions in same sensor family)
• 68146140AC (cross reference used in FCA catalog systems)

Typical applications include FCA 3.0 EcoDiesel platforms such as:

• Jeep Grand Cherokee WK2 3.0 EcoDiesel (2014–2020)
• Ram 1500 3.0 EcoDiesel (2014–2019)
• Ram 2500 / 3500 3.0 EcoDiesel (selected configurations)
• Ram ProMaster 1500 / 2500 / 3500 3.0 EcoDiesel (selected variants)

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, control regeneration cycles, and detect abnormal soot breakthrough in FCA diesel emissions systems.

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

Fitment must always be confirmed strictly by OEM number (68249512AC / 0281006338), as FCA uses multiple revisions across EcoDiesel platforms and model years.
