Within the past few years, the Environmental Protection Agency EPA has introduced strict emissions standards in order to reduce harmful pollutants from being released into the environment. It contains the diesel oxidation catalysts DOC , diesel particulate filters DPF , and selective catalytic reduction device SCR to ensure the air coming out of the engine is cleaner than the air going in. When exhaust exits the engine it is made up of carbon monoxide, hydrocarbons, and particulate matter. These are all harmful to the environment and must be captured in the 1-box before exiting through the exhaust outlet. The first defense after the exhaust leaves the engine is the diesel oxidation catalyst. The DOC is designed to convert the carbon monoxide and hydrocarbons into carbon dioxide and water. The DEF reacts with the nitrogen oxides in the SCR to form nitrogen and water which are both already present in the atmosphere and safe to breathe. After passing through the DOC the exhaust moves on to the diesel particulate filter. Every so often the 1-box needs to burn off this particulate matter and does so in a process called regeneration.

Circuit Description The aftertreatment particulate matter sensor is a smart device and communicates with the engine control module ECM via the J data link. The aftertreatment particulate matter sensor performs internal diagnostics and reports malfunctions back to the primary ECM using the J data link. The particulate matter sensor is permanently attached to the particulate matter control module. They are serviced as a single component and can not be replaced individually. The aftertreatment particulate matter sensor is used to measure the soot emissions at the outlet of the aftertreatment system. Component Location The aftertreatment particulate matter sensor location can vary depending on engine application.
