This is the Kobelco DEF Dcm Exh Nox Sensor, part number VI8978288390. NOx sensors in general measure the level of nitrogen oxides in exhaust gas and send that reading to the machine's control system. Order by the exact part number, because electrical sensors that look alike can differ in ways you cannot see from the outside.

In general, a NOx sensor in an exhaust system measures nitrogen oxide content in the exhaust gas and reports it to the machine's controller. The controller uses that information to monitor emissions-related operation.
Common signs include emissions-related fault codes, warning lights on the machine display, or diagnostic results that point to the sensor or its circuit. A fault code alone does not always mean the sensor has failed, so follow the machine's service manual for diagnosis before replacing it.
