Volvo All Engines (2013 Emissions) Fault Code: P040398 PID: EMS EGR “A” Control
Volvo All Engines (2013 Emissions) Fault Code: P040398 PID: EMS EGR “A” Control
Circuit description
The EGR Valve operation is controlled by the Engine Control Module (ECM) using a pulse width modulated signal.? The ECU provides both the power and ground circuits. The EGR Valve assembly consists of a solenoid, operating a valve by hydraulic pressure provided by the engine?s oiling system.
Conditions for diagnostic trouble code (DTC)
Too high temperature
Observable symptoms
Loss of power
Probable cause
1) EGR Valve
