Cummins ISX12 Aftertreatment Codes and Troubleshooting
The aftertreatment particulate matter sensor is a smart device and communicates with the engine control module (ECM) via the J1939 data link. The aftertreatment particulate matter sensor performs internal diagnostics and reports malfunctions back to the primary ECM using the J1939 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.
The aftertreatment particulate sensor is located after the aftertreatment selective catalytic reduction (SCR) catalyst. The aftertreatment particulate sensor is made up of three parts: Sensor probe mounted in the aftertreatment SCR catalyst outlet. Electronic module on the aftertreatment SCR catalyst. Wiring harness that connects sensor probe to the electronic module. The two parts are permanently connected and can not be separated. The aftertreatment particulate sensor can only be replaced as an assembly.
