Reason:Engine Torque Limit Feature – Special Instructions Effect:None on performance Circuit Description:This is an information only fault that will only become active if the engine has been operated above a calibrated torque threshold. Component Location:The ECM mounting location varies, depending on the engine model, and may be mounted either on or off the engine. Conditions for Running the Diagnostics:This diagnostic runs continuously when the engine is running. Conditions for Setting the Fault Codes:The Engine Control Module (ECM) detected the engine was being operated above the maximum torque threshold. Action Taken When the Fault Code is Active:The ECM illuminates the amber...

Reason:Aftertreatment Diesel Particulate Filter Outlet Pressure Sensor Circuit – Voltage Above Normal, or Shorted to High Source. High signal voltage detected at the aftertreatment diesel particulate filter outlet pressure sensor circuit. Effect:Possible reduced engine performance. Circuit Description:The engine control module (ECM) provides a 5 volt supply to the aftertreatment diesel particulate filter outlet pressure sensor on the sensor supply circuit. The ECM also provides a ground on the sensor return circuit. The aftertreatment diesel particulate filter outlet pressure sensor provides a signal to the ECM on the aftertreatment diesel particulate filter outlet pressure sensor signal circuit. This sensor signal voltage...

Reason:Aftertreatment Diesel Particulate Filter Outlet Pressure Sensor Circuit – Voltage Below Normal, or Shorted to Low Source. Low signal voltage detected at the aftertreatment diesel particulate filter outlet pressure sensor circuit. Effect:Possible reduced engine performance.
