Circuit DescriptionThe aftertreatment outlet NOx (nitrogen oxides) sensor is a smart device and communicates with the engine control module (ECM) via the J1939 data link. The aftertreatment outlet NOx sensor performs its own internal diagnostics and reports malfunctions back to the primary ECM with the J1939 data link. The NOx sensor is permanently attached to the NOx control module. They are serviced as a single component and can not be replaced individually. The aftertreatment outlet NOx sensor is used to measure the NOx emissions at the outlet of the aftertreatreatment system. Component LocationThe Aftertreatment Outlet NOx Sensor location can vary,...

Circuit DescriptionThe sensor supply 1 of the electronic control module (ECM) provides a 5 volt supply for the barometric pressure sensor, fuel rail pressure sensor, intake manifold temperature/pressure combination sensor, and camshaft speed/position sensor. Component LocationSensor supply number 1 is located in the ECM engine harness connector and provides a 5 volt supply to various pressure sensors. Conditions for Running the DiagnosticsThis diagnostic runs continuously when the keyswitch is in the ON position or when the engine is running. Conditions for Setting the Fault CodesThe ECM detects that the sensor supply 1 signal voltage is greater than 5.25-VDC for more...

Circuit DescriptionThe DEF quality sensor is a smart device and communicates with the engine electronic control module (ECM) via the J1939 data link. The DEF quality sensor receives power and ground directly from the battery. The sensor performs its own internal diagnostics and reports malfunctions back to the primary engine ECM via the J1939 data link. The DEF quality sensor is used to measure the concentration of the DEF in the tank. Component LocationThe DEF quality sensor is typically mounted in the DEF tank or in-line with the DEF dosing unit supply line. Reference the OEM service manual for a...
