Lamp:None Reason:An offset in the Selective Catalytic Reduction (SCR) outlet temperature sensor reading has been detected. Effect:Possible reduced engine performance. Circuit Description:The aftertreatment exhaust gas temperature sensor module is a smart device that communicates with the engine control module via the J1939 data link. The aftertreatment exhaust gas temperature sensor module performs its own internal diagnostics and reports malfunctions back to the engine control module using the J1939 data link. The aftertreatment exhaust gas temperature sensor module is used to measure the aftertreatment diesel oxidation catalyst intake temperature, aftertreatment diesel particulate filter intake temperature, aftertreatment diesel particulate filter outlet temperature,...

Lamp:Amber Reason:Measured EGR flow is higher than commanded. Effect:Possible reduced engine performance. Circuit Description:The Exhaust Gas Recirculation (EGR) differential pressure sensor has two ports that sense exhaust pressure. The sensor outputs a voltage which represents the pressure difference between the two ports located across an orifice in the EGR tube. The Engine Control Module (ECM) uses this pressure to determine how much exhaust gas is flowing in the EGR connection tube to the intake manifold. This information is used to control the EGR valve for correct emission levels. The ECM provides a 5 volt supply to the EGR differential pressure...
