Bosch 281007924 Particulate Matter (PM) Sensors

Bosch 281007924 Particulate Matter (PM) Sensors

Features:

• [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
• Ensures your Diesel Particulate Filter is working as intended
• [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
• [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
• [EASY INSTALL] – Engineered for quick installation with direct-fit connectors, standardized mounting threads, unoriented installation of sensor probe and included retaining screw to ensure hassle-free replacement
• [MADE IN USA] – Bosch proudly manufactures over 95% of Particulate Matter sensors for the North American market out of Anderson, SC — ensuring high quality and supply reliability

Bosch Particulate Matter (PM) sensors continuously monitor the function of the Diesel Particulate Filter (DPF) via direct measurement of soot concentration to help reduce particulate emissions by up to 99%. An evolution from older ΔP sensor’s indirect estimate of soot, Bosch pioneered resistive-measurement Particulate Matter sensors in order to provide precise real-time data to the ECU. With accurate soot data, the ECU can avoid unnecessary DPF regenerations – increasing fuel efficiency, reducing ash buildup, and extending the lifespan of aftertreatment components such as the Diesel Particulate Filter. Bosch offers a full line of robust, durable, and accurate Particulate Matter sensors to the aftermarket with the same sensors currently trusted by OE manufacturers.
