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 (> 30 kPa (4.4 psi / 8.8 in-Hg)) Observable symptoms1) Low Power2) Medium to high derate Probable cause1) Excessive smoke from the engine2) Aftertreatment diesel particulate filter (DPF) is loaded with soot3) Aftertreatment diesel particulate filter (DPF) is loaded with ash4)...

This diagnostic trouble code (DTC) indicates malfunction in the aftertreatment diesel exhaust fluid (DEF) tank heater valve or related wiring. The function of the aftertreatment DEF tank heater valve is to allow engine coolant flow to the aftertreatment DEF tank heater element which keeps the DEF from freezing. Frozen DEF may result in no DEF dosing which causes limited vehicle operation. Conditions for diagnostic trouble code (DTC):1) Aftertreatment diesel exhaust fluid (DEF) temperature too low Observable symptoms1) Possible engine de-rate Probable cause1) Mechanical fault2) Damaged or restricted actuator coolant lines3) Aftertreatment diesel exhaust fluid (DEF) tank heater valve Volvo All...
