Circuit DescriptionThe aftertreatment SCR intermediate NH3 (ammonia) sensor is a smart device that communicates with the engine control module via the J1939 data link. The aftertreatment intermediate NH3 sensor performs its own internal diagnostics and reports malfunctions back to the primary engine control module using the J1939 data link. The aftertreatment intermediate NH3 sensor is used to measure the ammonia in the aftertreatment system. Component LocationThe aftertreatment SCR intermediate NH3 sensor is located in the middle of the aftetreatment SCR catalyst. Conditions for Running the DiagnosticsThis diagnostic runs when the aftertreatment SCR intermediate temperature has been above 170 C [338...
