P0405 2007 Ford Fusion Code - Exhaust Gas Recirculation Sensor 'A' Circuit Low
Quick Answer
The EGR monitor checks the differential pressure feedback EGR sensor signal to the Powertrain Control Module (PCM) for low voltage. Common causes include Faulty EGR volume control solenoid valve, Carbon built up on EGR valve, EGR volume control solenoid valve harness is open or shorted. 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.
