Volvo All Engines (2013 Emissions) Fault Code: P04007C 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 above calculated value
EGR mass flow is below calculated value

Observable symptoms
Exhaust smoke

Probable cause
1) EGR Valve
