Compatible with Isuzu diesel emission aftertreatment systems using OEM references:

• 1275100944
• 8983550720
• 0281006991
• 0281007890
• 1277023203 (platform kit reference in some listings)

Typical applications include:

• Isuzu D-MAX 1.9 Ddi diesel (Euro 6 variants)
• Isuzu D-MAX 3.0 Ddi diesel (market-dependent emissions setup)
• Isuzu MU-X diesel models sharing DPF soot monitoring architecture
• Isuzu light-duty diesel platforms with Bosch PM sensor system

Function:
Installed after the diesel particulate filter (DPF), this sensor measures soot concentration in the exhaust stream. The ECU uses this signal to:

• verify DPF regeneration efficiency
• detect soot breakthrough or abnormal emissions
• optimize regeneration timing and intervals
• ensure compliance with Euro 6 emissions standards

⚠️ 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 critical for Isuzu diesel emission control and regeneration logic.

Fitment must always be confirmed strictly by OEM number (1275100944), as Isuzu uses multiple closely related sensor variants across D-MAX generations and regional emission calibrations.
