P1405 2009 Ford Fusion Code - Differential Pressure Feedback Sensor Upstream Hose Off or Plugged
Quick Answer
The purpose of the Exhaust Gas Recirculation (EGR) system on your engine is to limit oxides of nitrogen (NOx) emissions. Common causes include Faulty Differential Pressure Feedback Electronic (DPFE) sensor (EGR pressure sensor), Plugged or damaged EGR tube, Differential Pressure Feedback Electronic (DPFE) sensor 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.

Code P1405 2009 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 indicates EGR flow is in the negative direction.
What are the Possible Causes of the DTC P1405 2009 Ford Fusion?
- Faulty Differential Pressure Feedback Electronic (DPFE) sensor (EGR pressure sensor)
- Plugged or damaged EGR tube
- Differential Pressure Feedback Electronic (DPFE) sensor harness is open or shorted
- Differential Pressure Feedback Electronic (DPFE) sensor circuit poor electrical connection
