Cummins ISB4.5 CM2150 Fault Code: 3142 PID: SPN: 4360 FMI: 3 Aftertreatment SCR Intake Temperature Sensor Circuit – Voltage Above Normal or Shorted to High Source.
Posted by Diezel Solutions on
Circuit DescriptionThe SCR intake temperature sensor is used by the electronic control module (ECM) to monitor the engine exhaust temperature entering the SCR catalyst. The ECM monitors the voltage on the signal pin and converts this to a temperature value. Component LocationThe SCR intake temperature sensor is located in the aftertreatment system. It is located between the turbocharger outlet and the intake of the SCR catalyst in the exhaust system. 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 SCR intake temperature sensor...
