Fitment Level: OE Match / Platform Verified

Compatible with Mazda diesel emission aftertreatment systems using OEM references:

• SH9P-18641B
• SH9P18641B
• 0281007918
• 0281007919
• Bosch PM sensor family 0 281 007 918 / 0 281 007 919

Typical applications include:

• Mazda CX-5 KE / KF 2.2 Skyactiv-D diesel (2019–2023)
• Mazda CX-8 2.2 Skyactiv-D diesel (market-dependent)
• Mazda 6 GL/GJ 2.2 Skyactiv-D diesel (selected regions)
• Mazda Skyactiv-D Euro 6 diesel emission platforms

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 soot slip after regeneration
• optimize regeneration timing
• maintain Euro 6 emissions compliance

⚠️ 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 Mazda Skyactiv-D emissions control and regeneration logic.

Fitment must always be confirmed strictly by OEM number (SH9P-18641B / 0281007918), as Mazda diesel platforms vary by region and calibration level.
