Fitment Level: OE Match / Platform Verified

Compatible with Ford diesel emission aftertreatment systems using OEM references:

• LK21-5L216-BA
• LK21 5L216 BA
• 0281008347
• 0281008346
• Bosch PM sensor family 0 281 008 346 / 0 281 008 347

Typical applications include:

• Ford Transit Mk8 facelift / Mk9 2.0 EcoBlue diesel
• Ford Transit Custom 2.0 EcoBlue diesel
• Ford Ranger 2.0 EcoBlue diesel (Euro 6d variants)
• Ford light commercial Euro 6d diesel platforms with Bosch PM2 sensor system

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 after regeneration
• optimize regeneration timing and intervals
• improve emissions control accuracy in Euro 6d systems

⚠️ 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 essential for Ford EcoBlue emissions strategy and regeneration control logic.

Fitment must always be confirmed strictly by OEM number (LK21-5L216-BA / 0281008347), as Ford uses multiple revisions depending on vehicle type (Transit vs Ranger) and ECU calibration level.
