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) Valve is not opening properly Observable symptoms1) Engine de-rated2) Exhaust smoke Probable cause1) EGR Valve Volvo All Engines (2010 Emissions) Fault Code: SPN 2659 FMI 18 PID: PPID 35 Engine Exhaust Gas Recirculation (EGR) Mass Flow Rate – Modertaely Severe level Volvo All Engines (2010 Emissions) Fault...
