P0403 2011 Ford Fusion Code - Exhaust Gas Recirculation Control Circuit

Quick Answer

The EEGR system is continuously monitored to check the four EEGR motor coils, circuits, and the Powertrain Control Module (PCM) for opens, shorts to voltage and ground. Common causes include Faulty EGR volume control solenoid valve, EGR volume control solenoid valve harness is open or shorted, EGR volume control solenoid valve circuit poor electrical connection. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.
