The function identifies and indicates malfunction of the aftertreatment diesel particulate filter (DPF) by analyzing the pressure drop over the aftertreatment DPF. This is done by making a check for deviation between sensor value and a model pressure drop. In some extreme cases the engine will derate. Conditions for diagnostic trouble code (DTC):1) High differential pressure across the filter (DPF) Probable cause1) Aftertreatment DPF Differential Pressure Sensor2) Aftertreatment Diesel Particulate Filter (DPF) Volvo All Engines (2010 Emissions) Fault Code: SPN 3720 FMI 0 PID: PPID 337 Aftertreatment DPF Ash Load Percent Volvo All Engines (2010 Emissions) Fault Code: SPN 3695...
