Lamp:None Reason:An offset in the particulate matter sensor reading has been detected. Effect:Possible reduced engine performance. The aftertreatment particulate matter sensor is a smart device and communicates with the Engine Control Module (ECM) via the J1939 data link. Circuit Description:The aftertreatment particulate matter sensor is a smart device and communicates with the Engine Control Module (ECM) via the J1939 data link. The aftertreatment particulate matter sensor performs internal diagnostics and reports malfunctions back to the primary ECM using the J1939 data link. The particulate matter sensor is permanently attached to the particulate matter control module. They are serviced as a...

Lamp:None Reason:An offset in the diesel exhaust fluid tank temperature sensor reading has been detected. Effect:Possible reduced engine performance. Circuit Description:The aftertreatment diesel exhaust fluid tank temperature sensor is used to monitor the temperature of the aftertreatment diesel exhaust fluid inside the aftertreatment diesel exhaust fluid tank. Component Location:The aftertreatment diesel exhaust fluid tank temperature sensor is located in the diesel exhaust fluid tank. Location of the tank and temperature sensor is OEM dependent. Conditions for Running the Diagnostics:The engine must be turned OFF for period of 8 hours before this diagnostic will run. This diagnostic runs when the keyswitch...

Lamp:None Reason:An offset in the diesel exhaust fluid pressure sensor reading has been detected. Effect:Possible reduced engine performance. Circuit Description:The Engine Control Module (ECM) provides a 5 volt supply and a ground to the aftertreatment diesel exhaust fluid pressure sensor. The pressure sensor provides a signal to the ECM on the sensor signal circuit. This sensor signal voltage changes, based on the aftertreatment diesel exhaust fluid pressure supplied by the dosing unit. The ECM will detect a low signal voltage at low diesel exhaust fluid pressures, and a high signal voltage at high diesel exhaust fluid pressures. Component Location:The aftertreatment...
