Compatible with heavy-duty diesel vehicles equipped with exhaust particulate (PM) sensor systems using OEM references A0101538528 / A0111531328 / 0281007975 / 1275101167 / 1277023621 in diesel aftertreatment (DPF system).

Typical applications include:

• Detroit Diesel DD13 engine platforms
• Detroit Diesel DD15 engine platforms
• Detroit Diesel DD16 engine platforms
• Freightliner Cascadia / heavy-duty truck systems using Detroit DD-series engines
• 12V heavy-duty SCR + DPF emission systems
• Commercial diesel trucks requiring post-DPF soot monitoring

⚠️ Note: This is a post-DPF particulate matter (soot) sensor, not a NOx sensor or differential pressure sensor. It measures soot concentration after the diesel particulate filter to monitor filter efficiency and support regeneration control.

Function: Installed downstream of the DPF in the exhaust aftertreatment system, the sensor continuously sends particulate readings to the ECU/ACM. This allows accurate regeneration management, protects the DPF system, and ensures emissions compliance in heavy-duty diesel applications.
