VOLVOUU All Engines (2017 Emissions) Fault Code: P245264 PID: EMS Particulate Filter Pressure Sensor “A”

VOLVOUU All Engines (2017 Emissions) Fault Code: P245264 PID: EMS Particulate Filter Pressure Sensor “A”

Circuit description
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)
The sensor value is not within an expected range

Probable cause
1) DPF Sensor lines connected incorrectly
2) Aftertreatment diesel particulate filter (DPF) is damaged, soot loaded or missing
3) Differential pressure sensor lines plugged or damaged
4) Aftertreatment DPF Differential Pressure Sensor
5) Exhaust leakage
