Volvo All Engines (2017 Emissions) Fault Code: P040312 PID: EMS EGR “A” Control 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):1) Short circuit in component Observable symptoms1) Loss of power Probable cause1) EGR Valve Volvo All Engines (2017 Emissions) Fault Code: P040200 PID: EMS Engine Exhaust Gas Recirculation 1 Valve Position Flow Excessive Detected Volvo...
