Fitment Level: OE Match / Platform Verified

Compatible with Ford diesel emission aftertreatment systems using OEM references:

• JX61-5L239-EA
• 0281008188
• 2452751

Typical applications include Ford EcoBlue diesel platforms such as:

• Ford Focus Mk4 1.5 / 2.0 EcoBlue diesel (2018–2024)
• Ford Focus Active diesel variants
• Ford Focus Estate / Hatchback EcoBlue models (selected trims)
• Ford C-Max / related MQB diesel platform derivatives (market-dependent)

Supporting OE catalog data confirms this sensor is used in Ford DPF particulate matter monitoring systems, where it measures soot concentration downstream of the diesel particulate filter (DPF) to control regeneration strategy and emissions compliance.

⚠️ Important:
This is a DPF particulate matter (PM) sensor, not a NOx or temperature sensor.
It directly measures exhaust soot loading after the diesel particulate filter and sends real-time data to the ECU for regeneration control, DPF efficiency tracking, and emissions diagnostics.

Fitment must always be confirmed strictly by OEM number (JX61-5L239-EA / 0281008188), as Ford EcoBlue platforms use multiple revisions across Focus Mk4 production years and engine calibrations.
