Volvo All Engines (2013 Emissions) Fault Code: P04009C PID: EMS Exhaust Gas Recirculation “A” Flow

Volvo All Engines (2013 Emissions) Fault Code: P04009C PID: EMS Exhaust Gas Recirculation “A” Flow

Circuit description
This function is used to calculate the EGR Mass Flow. The Engine Control Module (ECM) monitors the EGR differential pressure sensor and the EGR temperature sensor after cooler and uses these signals to calculate the EGR Mass Flow data.

Conditions for diagnostic trouble code (DTC)
EGR mass flow is below calculated value

Probable cause
1) EGR Cooler
2) Connector
3) Wiring harness
4) EGR Valve
5) Exhaust leakage
6) EGR differential pressure sensor

Detailed information
The EGR mass flow is an calculated value based on a number of sensor signals and software calculations

The diagnostic trouble code (DTC) will be shown as inactive when the ignition key is turned to the 0 position

To fully verify the repair it may be necessary to activate vehicle functions or perform a test drive

One or more diagnostic trouble codes (DTC) have been set for faults in the EGR system
