P1406 2010 FORD FUSION Meaning

The purpose of the Exhaust Gas Recirculation (EGR) system on your engine is to limit oxides of nitrogen (NOx) emissions. This is done by redirecting small amounts of exhaust gas back through the upper intake to get mixed in with the air/fuel charge.
While driving, the exhaust gas recirculation (EGR) monitor commands the EGR valve closed and checks the differential pressure across the EGR orifice. The test fails when the signal from the differential pressure feedback EGR sensor continues to indicate EGR flow even after the EGR valve is commanded closed.
