Bosch LR146853 Diesel Particulate Matter Sensor

The Bosch LR146853 (Bosch part number 0281008516) is a Diesel Particulate Filter (DPF) Pressure Sensor designed for precise monitoring of diesel particulate filter performance. This particulate matter sensor continuously monitors the function of the Diesel Particulate Filter via direct measurement of soot concentration to help reduce particulate emissions by up to 99%.

Key Features:

• Uses resistive-measurement technology to provide precise real-time data to the ECU, an evolution from older differential pressure sensors
• Functional principle based on resistance measurement where soot particles are deposited on an electrode structure and form conductive soot trails between electrodes
• Self-regenerating sensor element through heating to ensure defined status before each measurement
• Accurate soot data helps avoid unnecessary DPF regenerations, increasing fuel efficiency and extending aftertreatment component lifespan
• OEM quality construction meeting manufacturer specifications

This genuine particulate matter detect sensor is designed for 3.0 TDV6 Gen2 and 4.4 TDV8 diesel engines. OEM part number LR146853 replaces LR071752, LR110294, and LR114277. Bosch offers robust, durable, and accurate particulate matter sensors to the aftermarket with the same quality currently trusted by OE manufacturers.
