Compatible with Ford diesel emission aftertreatment systems using OEM references:

• 1277023505
• 0281007519
• KV61-5L239-AA / related Ford EcoBlue PM sensor family (platform dependent)

Typical applications include:

• Ford Transit Connect 1.5 EcoBlue diesel
• Ford Transit Custom EcoBlue diesel (selected Euro 6 variants)
• Ford Transit / Tourneo EcoBlue diesel platforms
• Some Ford Focus / small commercial diesel configurations (market dependent)

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 slip or abnormal emissions
• optimize regeneration timing
• maintain Euro 6 emissions compliance and diagnostics accuracy

⚠️ 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 essential for Ford EcoBlue diesel emission control systems.

Fitment must always be confirmed strictly by OEM number (1277023505), as Ford uses multiple closely related PM sensor variants across Transit and EcoBlue engine generations depending on ECU calibration.
