Volvo All Engines (2010 Emissions) Fault Code: SPN 411 FMI 12 PID: Engine Exhaust Gas Recirculation Differential Pressure

This Diagnostic Trouble Code (DTC) monitors and evaluates malfunctions in the (EGR) Exhaust Gas Recirculation Diff Pressure. A faulty (EGR) Exhaust Gas Recirculation differential Pressure can lead to uneven running and response problems.

Conditions for diagnostic trouble code (DTC):
1) Abnormal system response, most likely high flow

Observable symptoms
1) Possible engine de-rate
2) Exhaust leakage

Probable cause
1) Connector
2) Wiring harness
3) Clogged ports
4) EGR Cooler
5) EGR system pipe and connections
6) EGR differential pressure sensor

Detailed information

Activation
1) The diagnostic trouble code (DTC) is first set after 30?min when driving with varying engine loads
2) At idle the diagnostic trouble code (DTC) is normally not set to active

Deactivation
1) The diagnostic trouble code (DTC) will be shown as inactive when the ignition key is turned to the 0 position
2) To fully verify the repair it may be necessary to activate vehicle functions or perform a test drive
