Compatible with Mazda diesel vehicles equipped with exhaust particulate (PM) sensor systems using OEM references SH9P-18641B / 0281007918 / 0281007919 / 1277023473 / 1277023474 in diesel aftertreatment (DPF system).

Typical applications include:

• Mazda CX-5 2.2 Skyactiv-D (KE / KF platform, 2019–2023)
• Mazda diesel variants using Bosch-type DPF soot monitoring system
• Vehicles equipped with diesel particulate filter (DPF) regeneration feedback sensor system
• Mazda Euro 6 diesel emission configurations with post-DPF particulate measurement

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

Function: Installed downstream of the DPF in the exhaust system, the sensor continuously reports particulate load to the ECU. This enables accurate regeneration timing, prevents DPF clogging, and ensures emissions compliance.
