Compatible with Isuzu diesel emission aftertreatment systems using OEM references:

• 8982759090
• 8-98275909-0
• 0281007889
• 0281006661 (catalog-dependent cross reference)

Typical applications include:

• Isuzu NPR / NPR-HD diesel trucks
• Isuzu NQR / NRR medium-duty diesel trucks
• Isuzu FTR diesel (selected export emission configurations)
• Isuzu 4HK1 / 4JJ1 diesel engines with DPF soot monitoring systems

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 cycles
• ensure Euro 6 emissions compliance in commercial diesel operation

⚠️ 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 essential for Isuzu diesel emission control and regeneration logic.

Fitment must always be confirmed strictly by OEM number (8982759090), as Isuzu uses multiple closely related revisions across truck platforms and ECU calibration variants.
