Volvo All Engines (2013 Emissions) Fault Code: P242F00 PID: EMS Diesel Particulate Filter Restriction – Ash Accumulation Bank 1

Circuit description
This function is used to determine the level of ash in the diesel particle filter. When the level of ash is too high, a cleaning of the filter is necessary. To determine the level of ash, three different signal/parameters is used; accumulated distance since last cleaning, accumulated time since last cleaning and a calculated value.

Conditions for diagnostic trouble code (DTC)
Ash level too high

Observable symptoms
None

Probable cause
1) Aftertreatment diesel particulate filter (DPF) is loaded with ash

Volvo All Engines (2013 Emissions) Fault Code: P244A00 PID: EMS Aftertreatment 1 Diesel Particulate Filter Differential Pressure Too Low (Bank 1)

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

Volvo All Engines (2013 Emissions) Fault Code: P244B00 PID: EMS Aftertreatment 1 Diesel Particulate Filter Differential Pressure Too High (Bank 1)

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 cause
1) Aftertreatment DPF Differential Pressure Sensor
2) Aftertreatment Diesel Particulate Filter (DPF)

Observable symptoms
1) Regeneration aborted

Probable cause
1) Fuel line(s), Leakage
2) Obstructed/dirty aftertreatment hydrocarbon doser
3) Catalyst failure
