Fitment Level: OE Match / Platform Verified

Compatible with Isuzu diesel emission aftertreatment systems using OEM references:

• 8975394320
• 0281008270
• 0281008271
• Bosch PM sensor family 0 281 008 270 / 0 281 008 271

Typical applications include:

• Isuzu D-Max II 1.9 Ddi (RZ4E-TC diesel engine)
• Isuzu D-Max II 3.0 Ddi diesel (selected markets)
• Isuzu MU-X diesel (shared DPF architecture in some regions)
• Isuzu Euro 6 diesel platforms with Bosch PM sensing system

This sensor is used in diesel particulate matter monitoring systems, where it measures soot concentration downstream of the diesel particulate filter (DPF). The ECU uses this signal to:

• evaluate DPF regeneration efficiency
• detect abnormal soot slip after regeneration
• optimize regeneration strategy
• maintain 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 after the DPF and is essential for Isuzu diesel emission system control and regeneration logic.

Fitment must always be confirmed strictly by OEM number (8975394320 / 0281008270), as Isuzu D-Max variants differ by engine (1.9 vs 3.0) and regional emission calibration.
