Compatible with FCA diesel emission aftertreatment systems using OEM references:

• 68201262AA
• 68201262AB (revision supersession in some applications)
• FCA EcoDiesel PM sensor platform (Bosch-based architecture)

Typical applications include:

• Ram 1500 EcoDiesel diesel variants
• Ram 2500 / 3500 diesel emission configurations (market-dependent systems)
• Jeep Grand Cherokee 3.0 EcoDiesel
• Jeep Wrangler diesel export models (select regions)

Function:
Installed after the diesel particulate filter (DPF), this sensor continuously measures soot concentration in the exhaust stream. The ECU uses this signal to:

• verify DPF regeneration efficiency
• detect soot breakthrough or filter degradation
• optimize regeneration cycles
• maintain Euro 6 emissions compliance

⚠️ Important
This is a DPF particulate matter (PM) sensor, not a NOx or pressure sensor. It directly measures soot concentration downstream of the diesel particulate filter and is critical for FCA diesel emission control and regeneration logic.

Fitment must always be confirmed strictly by OEM number (68201262AA), as FCA uses multiple revisions (AA / AB / AC) across different model years and calibration updates.
