Compatible with Ford diesel vehicles equipped with exhaust particulate (PM) sensor systems using OEM references LK21-5L216-BA / LK21-5L216-AB / 0281008347 / 0281008346 / 1277023595 / 670105053 in diesel aftertreatment (DPF system).

Typical applications include:

• Ford Transit 2.0 EcoBlue diesel (2017–2021)
• Ford Transit Custom 2.0 EcoBlue diesel variants
• Ford commercial diesel platforms using Bosch PM2.2 sensor architecture
• Vehicles equipped with diesel particulate filter (DPF) soot monitoring system for regeneration feedback
• Euro 6 diesel emission systems with post-DPF particulate measurement

⚠️ Note: This is a post-DPF particulate matter (soot) sensor, not a NOx sensor or pressure sensor. It measures soot concentration after the diesel particulate filter to monitor efficiency and control regeneration cycles.

Function: Installed downstream of the DPF in the exhaust system, the sensor continuously reports particulate load to the ECU. This allows precise regeneration control, early detection of DPF issues, and stable emissions performance.
