Volvo All Engines (2010 Emissions) Fault Code: SPN 3064 FMI 0 PID: PPID 326 Aftertreatment DPF Soot Level

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 load
2) Aftertreatment diesel particulate filter (DPF) soot load ratio more than 140 %

Observable symptoms
1) Low Power

Probable cause
1) Regeneration process is not functioning
2) Regeneration inhibited, driver has not allowed regeneration to take place
3) Aftertreatment Hydrocarbon Doser
4) Catalyst

Detailed information
1) Engine control module (ECM) commands the exhaust gas recirculation (EGR) valve to close when the aftertreatment diesel particulate filter (DPF) soot load ratio is more than 140 %
2) Medium to high derate
