This function is used to determine the level of soot in the diesel particulate filter (DPF). This is done by using four different signal/parameters; estimated driving distance since last aftertreatment DPF regeneration, the time since last regeneration, fuel consumption and the aftertreatment DPF pressure. When this diagnostic trouble code (DTC) is set the filter needs servicing due to high level of soot or the aftertreatment DPF regeneration process does not function properly. Conditions for diagnostic trouble code (DTC):1) Moderately high soot load2) Aftertreatment diesel particulate filter (DPF) soot load ratio more than 140 % Observable symptoms1) Low Power Probable cause1)...

This diagnostic function monitors the aftertreatment DPF temperature sensors and DPF soot level during normal operation. Based upon the operating conditions and DPF soot level the ECU decides if the engine should be de-rated in order to protect the DPF system components.This diagnostic trouble code (DTC) can only occur during normal operating conditions, aftertreatment diesel particulate filter (DPF) regeneration process not active. In some cases extreme driving conditions can cause soot in the DPF to oxidize at an unacceptable rate and cause DPF damage. Conditions for diagnostic trouble code (DTC):1) Overheating the DPF due to soot oxidation during extreme driving...

The NOx sensor measures the amount of NOx in the exhaust system. The NOx sensor is connected in the J1939-2 data link. This diagnostic trouble code (DTC) indicates a NOx monitoring failure. For example; NOx sensor short- or open circuit, NOx sensor removed, NOx sensor missing signal. Observable symptoms1) None Probable cause1) Sensor not mounted in exhaust stream2) Software3) NOx sensor Volvo All Engines (2010 Emissions) Fault Code: SPN 3064 FMI 11 PID: PPID 326 Aftertreatment DPF Soot Level Volvo All Engines (2010 Emissions) Fault Code: SPN 3064 FMI 10 PID: PPID 326 Aftertreatment DPF Soot Level Volvo All Engines...
