Fitment Level: OE Match / Platform Verified

Compatible with Ford diesel emission aftertreatment systems using OEM references:

• JX61-5L239-DB
• 0281007641
• 2328359 (Ford service reference in some catalog listings)

Typical applications include Ford EcoBlue diesel platforms such as:

• Ford Focus Mk4 1.5 EcoBlue diesel (2019–2024)
• Ford Focus Mk4 2.0 EcoBlue diesel (selected variants)
• Ford Focus Active diesel models
• Ford Focus Estate / Hatchback EcoBlue configurations

Supporting OE catalog data confirms this sensor is used in Ford DPF particulate matter monitoring systems, where it measures soot loading downstream of the diesel particulate filter (DPF) and sends real-time feedback to the ECU for regeneration control and emissions diagnostics.

⚠️ Important:
This is a diesel particulate matter (PM) sensor, not a NOx, temperature, or pressure sensor.
It directly measures post-DPF soot concentration and is critical for regeneration strategy, DPF efficiency monitoring, and emissions compliance.

Fitment must always be confirmed strictly by OEM number (JX61-5L239-DB / 0281007641), as Ford EcoBlue systems use multiple revisions across Focus Mk4 model years.
