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) DPF Differential pressure too low
Observable symptoms
1) None
Probable cause
1) DPF Sensor lines connected incorrectly
2) Differential pressure sensor lines plugged or damaged
3) Aftertreatment DPF Differential Pressure Sensor
4) Aftertreatment Diesel Particulate Filter (DPF)
5) Exhaust leakage prior to the aftertreatment diesel particulate filter (DPF) unit
