Cummins ISB4.5 CM2150 Fault Code: 3236 PID: SPN: 4363 FMI: 16 Aftertreatment SCR Outlet Temperature – Data Valid But Above Normal Operating Range – Moderately Severe Level.
Posted by PerDiezel Solutions on
Circuit DescriptionThe selective catalytic reduction (SCR) outlet gas temperature sensor is used by the engine control module (ECM) to monitor the engine exhaust gas temperature exiting the catalyst. The ECM monitors the voltage on the SIGNAL pin and converts this to a temperature value. Component LocationThe SCR outlet exhaust gas temperature sensor is located in the exhaust aftertreatment system. It is located at the outlet of the SCR catalyst. Conditions for Running the DiagnosticsThis diagnostic runs continuously when the keyswitch is in the ON position. Conditions for Setting the Fault CodesThe ECM detects that the temperature at the SCR catalyst...
