Code P1408 2007 Ford Fusion Description
The P1408 diagnostic trouble code (DTC) for a 2007 Ford Fusion indicates that there is an issue with the Exhaust Gas Recirculation (EGR) system. Specifically, the EGR flow is detected to be out of the self-test range. The EGR system plays a crucial role in reducing harmful emissions by recirculating a portion of the exhaust gases back into the combustion chambers to be re-burned. When the EGR flow is not within the expected range, it can lead to a variety of performance issues and potential long-term effects on the vehicle's systems.
Common Causes of P1408 2007 Ford Fusion
- Faulty EGR valve
- Clogged EGR passages
- Malfunctioning EGR solenoid
- Defective EGR sensor
- Wiring or electrical issues in the EGR system
Symptoms of P1408 2007 Ford Fusion
- Reduced fuel economy
- Decreased power output
- Rough idling or stalling
- Hesitation during acceleration
- Check Engine Light illuminated
How to Fix P1408 2007 Ford Fusion
- Perform a diagnostic scan to confirm the P1408 code and identify the specific cause of the issue.
- Inspect the EGR valve, passages, solenoid, and sensor for any signs of damage or blockages.
- Clean or replace the EGR components as necessary.
- Reset the ECU to clear the code and monitor the EGR system's performance.
- Test drive the vehicle to ensure that the issue has been resolved and the code does not reappear.
Cost to Fix P1408 2007 Ford Fusion
The typical repair costs for addressing a P1408 code on a 2007 Ford Fusion can range from $200 to $500, including parts and labor.

Frequently Asked Questions about P1408 2007 Ford Fusion Code
1. What does the OBDII code P1408 mean on a 2007 Ford Fusion?
P1408 indicates that the EGR (Exhaust Gas Recirculation) flow is out of the self-test range, meaning the engine control module (ECM) has detected an issue with the EGR system's performance.
2. What are the common symptoms of the P1408 code on a 2007 Ford Fusion?
Symptoms may include a lit check engine light, rough idling, decreased fuel efficiency, engine hesitation, or increased exhaust emissions.
3. What causes the P1408 code to appear on a 2007 Ford Fusion?
Common causes include a clogged or stuck EGR valve, faulty EGR sensors, damaged vacuum hoses, carbon buildup in EGR passages, or issues with the ECM.
4. Can a clogged EGR valve trigger the P1408 code?
Yes, a clogged or stuck EGR valve is one of the most common causes of the P1408 code, as it disrupts proper exhaust gas flow.
5. How do I diagnose the P1408 code on my 2007 Ford Fusion?
Start by checking for carbon buildup in the EGR valve or passages, inspecting vacuum hoses for leaks, testing the EGR valve function, and using a scan tool to monitor live data from the EGR system.
6. Can I drive my 2007 Ford Fusion with the P1408 code?
While it may be possible to drive, ignoring the code can lead to reduced engine performance, increased emissions, and potential damage to the catalytic converter over time.
7. How do I fix the P1408 code on a 2007 Ford Fusion?
Common fixes include cleaning or replacing the EGR valve, clearing blockages in the EGR passages, repairing vacuum leaks, and replacing faulty EGR sensors if necessary.
8. Will clearing the P1408 code with a scan tool solve the problem?
Clearing the code will reset the check engine light, but it won’t fix the underlying issue. The problem must be diagnosed and repaired to prevent the code from returning.
9. Can a faulty ECM cause the P1408 code on a 2007 Ford Fusion?
While rare, a malfunctioning ECM can cause the P1408 code. However, it's more likely caused by issues with the EGR system itself.
10. What tools are needed to address the P1408 code on a 2007 Ford Fusion?
You may need a scan tool, a vacuum pump, basic hand tools, and possibly cleaning supplies (e.g., carb cleaner) to address the EGR system issues.
