Bosch 0281007095 Particulate Matter Sensor for Diesel Particulate Filter DPF

The Bosch 0281007095 is an OE-quality Particulate Matter (PM) Sensor designed to continuously monitor the performance of the Diesel Particulate Filter (DPF) through direct, real-time measurement of exhaust soot concentration. As the pioneer of resistive-measurement PM sensor technology, Bosch engineered this sensor to deliver precise soot data to the vehicle's ECU, enabling intelligent DPF management and helping reduce particulate emissions by up to 99%.

Key Features:

• Direct Soot Measurement: Uses resistance-based sensing — soot particles deposit on an internal electrode structure, forming conductive trails measured in real time, far more accurate than older differential pressure (ΔP) indirect estimates
• Self-Regenerating Sensor Element: An integrated heater regenerates the sensor element before each measurement cycle, ensuring a consistent baseline — no learning cycles, flow calculations, or baseline mapping required
• Factory Pre-Calibrated SCU: The included Sensor Control Unit (SCU) is pre-calibrated at the factory for plug-and-play installation
• CAN-Bus Communication: Communicates directly with the ECU via CAN-bus interface to enable real-time OBD fault detection, DPF failure diagnostics, and fleet emission monitoring
• Low Soot Detection: Optimized for detection down to 1 mg/m³ with fast response time to minimize unnecessary DPF regeneration cycles
• Robust Construction: Features a stainless steel sensor housing and molded SCU for long-term durability and dependable operation
• OE-Equivalent Quality: Engineered and manufactured to the same rigorous standards as original equipment sensors, meeting Euro 6 and EPA emission requirements
• Also known as: EGSPM2, particulate probe, DPF soot sensor, PM sensor

By supplying accurate soot concentration data to the ECU, the Bosch 0281007095 helps avoid unnecessary DPF regenerations — improving fuel efficiency, reducing ash buildup, and extending the service life of downstream aftertreatment components. This sensor is application-specific and factory-tuned to its internal sensing materials.
