Compatible with Isuzu diesel emission aftertreatment systems using OEM references:

• 8978808270
• 8-97880-827-0
• 0281009338
• 0281009339

Typical applications include:

• Isuzu NPR Euro 6 diesel trucks
• Isuzu NQR / NRR medium-duty trucks
• Isuzu 4HK1 / 4JJ1 diesel engines with DPF systems
• Isuzu commercial diesel platforms using Bosch PM sensor architecture

Function:
Installed after the diesel particulate filter (DPF), this sensor continuously 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
• support Euro 6 emissions compliance and diagnostics

⚠️ 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 strategy.

Fitment must always be confirmed strictly by OEM number (8978808270), as Isuzu uses multiple closely related sensor variants across different truck models and ECU calibrations.
