Bosch 281009003 Particulate Matter (PM) Sensors

Bosch 281009003 Particulate Matter (PM) Sensors

Features:

[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
[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
[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
[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
[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
[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

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.
