P1405 2007 Ford Fusion Code - Differential Pressure Feedback Sensor Upstream Hose Off or Plugged
Quick Answer
The P1405 diagnostic trouble code (DTC) for a 2007 Ford Fusion indicates that the Differential Pressure Feedback Sensor (DPFE) upstream hose is either disconnected or obstructed. Common causes include Disconnected Hose: The upstream hose of the DPFE sensor may have become disconnected due to vibrations or wear over time, Hose Obstruction: Debris or carbon buildup in the hose can obstruct the flow of exhaust gas, leading to inaccurate sensor readings, Sensor Failure: The DPFE sensor itself may be faulty and need to be replaced. 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 2007 Ford Fusion Description
The P1405 diagnostic trouble code (DTC) for a 2007 Ford Fusion indicates that the Differential Pressure Feedback Sensor (DPFE) upstream hose is either disconnected or obstructed. The DPFE sensor is a crucial component of the vehicle's exhaust gas recirculation (EGR) system, which helps reduce emissions and improve fuel efficiency. The sensor measures the pressure difference between the exhaust gas before and after it passes through the EGR valve, allowing the engine control module (ECM) to adjust the EGR flow rate accordingly.
Common Causes of P1405 2007 Ford Fusion
- Disconnected Hose: The upstream hose of the DPFE sensor may have become disconnected due to vibrations or wear over time.
- Hose Obstruction: Debris or carbon buildup in the hose can obstruct the flow of exhaust gas, leading to inaccurate sensor readings.
- Sensor Failure: The DPFE sensor itself may be faulty and need to be replaced.
- Wiring Issues: Electrical problems such as a damaged wire or poor connection can also trigger this code.
- EGR Valve Malfunction: A malfunctioning EGR valve can cause abnormal pressure readings in the DPFE sensor.
Symptoms of P1405 2007 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 stalling due to incorrect EGR flow rates.
- Decreased Fuel Efficiency: A malfunctioning DPFE sensor can lead to decreased fuel efficiency as the engine may not be operating optimally.
- Increased Emissions: The vehicle may fail emissions tests due to increased emissions caused by improper EGR system operation.
How to Fix P1405 2007 Ford Fusion
- Inspect Hose: Check the upstream hose of the DPFE sensor for any signs of disconnection or blockage. Reconnect or clear any obstructions as necessary.
- Test Sensor: Use a multimeter to test the DPFE sensor for proper functionality. Replace the sensor if it is found to be faulty.
- Check Wiring: Inspect the wiring harness connected to the DPFE sensor for any damage or loose connections. Repair or replace any damaged wires.
- Clear Codes: After addressing 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 has resolved the issue and that the check engine light does not reappear.
Cost to Fix P1405 2007 Ford Fusion
The cost of repairing a P1405 DTC on a 2007 Ford Fusion can vary depending on the specific cause of the issue. In general, replacing the DPFE sensor or repairing the hose may cost between $100 and $300, including parts and labor. However, if additional components need to be replaced or if wiring repairs are necessary, the cost could increase. It's recommended to consult with a qualified mechanic or auto repair shop for a more accurate estimate based on the specific circumstances of the vehicle. Keep in mind that labor rates can vary between different locations and types of repair facilities.
