P1405 2006 Ford Fusion Code - Differential Pressure Feedback Sensor Upstream Hose Off or Plugged
Quick Answer
The P1405 diagnostic trouble code (DTC) for a 2006 Ford Fusion specifically refers to the Differential Pressure Feedback Sensor (DPFE) Upstream Hose being either disconnected, blocked, or damaged. Common causes include Loose or Disconnected Hose: The upstream hose connecting the DPFE sensor to the EGR system may have come loose or disconnected, Hose Blockage: The hose could be blocked by debris or carbon buildup, restricting the flow of exhaust gases, Damaged Hose: The hose may be damaged or deteriorated, causing leaks or improper pressure readings. 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 2006 Ford Fusion Description
The P1405 diagnostic trouble code (DTC) for a 2006 Ford Fusion specifically refers to the Differential Pressure Feedback Sensor (DPFE) Upstream Hose being either disconnected, blocked, or damaged. The DPFE sensor is a crucial component of the vehicle's exhaust gas recirculation (EGR) system, which is responsible for reducing harmful emissions by recirculating a portion of the exhaust gases back into the engine for combustion.
Common Causes of P1405 2006 Ford Fusion
- Loose or Disconnected Hose: The upstream hose connecting the DPFE sensor to the EGR system may have come loose or disconnected.
- Hose Blockage: The hose could be blocked by debris or carbon buildup, restricting the flow of exhaust gases.
- Damaged Hose: The hose may be damaged or deteriorated, causing leaks or improper pressure readings.
- Faulty DPFE Sensor: The DPFE sensor itself may be faulty, providing inaccurate readings to the ECM.
Symptoms of P1405 2006 Ford Fusion
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the vehicle's dashboard.
- Rough Idle: The engine may experience rough idling or hesitation during acceleration due to incorrect EGR valve operation.
- Decreased Fuel Efficiency: A malfunctioning DPFE sensor can lead to decreased fuel efficiency as the engine may not be running optimally.
- Increased Emissions: The vehicle may fail emissions tests or emit higher levels of pollutants due to improper EGR system operation.
How to Fix P1405 2006 Ford Fusion
- Inspection: Begin by visually inspecting the upstream hose for any signs of damage, blockage, or disconnection.
- Hose Replacement: If the hose is damaged or blocked, replace it with a new one to ensure proper flow of exhaust gases.
- DPFE Sensor Replacement: If the sensor is faulty, replace it with a new OEM or high-quality aftermarket sensor to restore accurate readings.
- Clear Codes: After repairing the issue, clear the DTC using an OBD-II scanner to reset the check engine light.
- Test Drive: Take the vehicle for a test drive to ensure that the repair resolved the issue and that the check engine light does not reappear.
