Bosch Diesel Particulate Matter PM Sensor

The Bosch Diesel Particulate Matter (PM) Sensor monitors the amount of soot in the exhaust stream downstream of the diesel particulate filter (DPF). Also called a soot sensor or diesel particulate sensor, it helps the engine control system check that the DPF is working properly and detect filter damage or leakage.

Key Features:

• Measures soot particles in the exhaust gas after the diesel particulate filter
• Supports on-board diagnostics by giving the engine control unit data on DPF efficiency
• Helps the vehicle meet diesel emissions requirements
• Built by Bosch, a leading OE supplier of diesel and emissions-control components
• Made to withstand the high heat, vibration and harsh conditions of a diesel exhaust system

A working PM sensor helps keep the emissions system running as designed and helps prevent unnecessary warning lights or diagnostic faults from the exhaust aftertreatment system. Select the correct part number from the variants listed on this page.
