Reason:Aftertreatment SCR Intake Temperature Sensor Circuit – Voltage Below Normal or Shorted to Low Source. Low signal voltage detected at the SCR intake temperature sensor circuit. Effect:Possible reduced engine performance. Circuit Description:The aftertreatment SCR (selective catalytic reduction) temperature sensor module is a smart device that communicates with the engine control module via the J1939 data link. The aftertreatment SCR temperature sensor module performs its own internal diagnostics and reports malfunctions back to the engine control module using the J1939 data link. The aftertreatment SCR temperature sensor module is used to measure the aftertreatment SCR intake temperature and aftertreatment SCR outlet...
