Volvo All Engines (2010 Emissions) Fault Code: SPN 3485 FMI 7 PID: Aftertreatment DPF Atomization Air Pressure
The aftertreatment diesel particulate filter (DPF) atomization air pressure sensor is used to monitor the pressure of the compressed air supply to the aftertreatment DPF atomization module during active diagnostics and measures the combined atomization fuel and air pressure during burner operation. The sensor consists of a pressure sensitive diaphragm/amplifier sensor. Air pressure causes the sensors diaphragm to deflect and produce an electrical signal proportional to the pressure. The diaphragm deflection signal is amplified in the sensor.
Conditions for diagnostic trouble code (DTC):
1) Low air pressure detected during active diagnostics check of the pressure regulator in the aftertreament diesel particulate filter (DPF) atomization module
Observable symptoms
1) Regeneration not possible
Probable cause
1) Aftertreatment Diesel Particulate Filter (DPF) Atomization Module (Internal air pressure regulator)
2) Low air pressure
3) Steel fuel line
4) Diesel Particulate Filter (DPF) Air shutoff Valve
5) Aftertreatment DPF Atomization Air Pressure Sensor
