Code P1406 2012 Ford Fusion Description
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.
What are the Possible Causes of the DTC P1406 2012 Ford Fusion?
- Downstream hose is disconnected
- Downstream hose is plugged (ice)
- Plugged or damaged Exhaust Gas Recirculation (EGR) tube
- Faulty Differential Pressure Feedback Electronic (DPFE) sensor
- Differential Pressure Feedback Electronic (DPFE) sensor harness is open or shorted
- Differential Pressure Feedback Electronic (DPFE) sensor circuit poor electrical connection
How to Fix the DTC P1406 2012 Ford Fusion?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
