Particulate Matter (PM) Sensors

Key Features

• [SUPERIOR PERFORMANCE] – Bosch Particulate Matter sensors help reduce particulate emissions by up to 99% and DPF regeneration cycles — increasing fuel efficiency, reducing ash buildup, and extending the lifespan of aftertreatment components
• [OE-TRUSTED] – Bosch pioneered Particulate Matter sensors optimized for low soot detection (down to 1 mg/m³), fast response time, and reduced DPF regeneration cycles — securing Bosch as the OE choice for 100% of on-highway applications in N
• [LONG LIFETIME] – With a service life of up to 155,000 mi, Bosch Particulate Matter sensors feature robust construction — including stainless steel sensor housings and molded Sensor Control Units to ensure dependable operation in the hars
• [PRE-CALIBRATED] – Bosch Particulate Matter Sensor Control Units (SCU) are factory pre-calibrated, with a self-reset feature via integrated heater — no need for baseline mapping, flow calculations, or learning cycles
• [LOW AGING SENSITIVITY] – Unlike a ΔP sensor which can skew readings based on filter flow dynamics, a Particulate Matter sensor measures soot regardless of DPF condition — ensuring consistent performance throughout the service life of the f
• [ADVANCED DIAGNOSTICS] – With direct ECU communication via CAN-bus interface, Bosch Particulate Matter sensors enable onboard diagnostics of DPF failure for real-time engine management, OBD fault detection, and fleet emission monitoring
