Fitment Level: OE Match / Platform Verified

Compatible with Ford diesel emission aftertreatment systems using OEM references:

• JK4Z-5L239-B
• JK4Z-5L239-A (previous revision)
• Ford service reference: Diesel Particulate Sensor Assembly (3.2L Duratorq / Puma engine platform)

Typical applications include Ford commercial diesel platforms such as:

• Ford Transit Mk8 3.2L Duratorq-TDCi diesel (2018–2019)
• Ford Transit 350 / 150 HD diesel (selected configurations)
• Ford chassis cab 3.2L diesel (Euro 6 emission system variants)

This sensor is used in Ford DPF particulate matter monitoring systems, where it measures soot concentration downstream of the diesel particulate filter (DPF) to evaluate regeneration efficiency and emissions compliance.

⚠️ Important:
Although often listed in catalogs as a “pressure sensor,” this unit functions as a diesel particulate matter (PM) sensor module in the exhaust system.
It monitors soot passing the DPF and sends data to the ECU for regeneration control, DPF efficiency evaluation, and fault detection.

Fitment must always be confirmed strictly by OEM number (JK4Z-5L239-B), as Ford uses different sensor revisions across Transit 3.2L emission configurations.
