P1407 Ford Code - Exhaust Gas Recirculation Flow Out Of Self-Test Range
Quick Answer
The P1407 Ford code indicates that there is an issue with the Exhaust Gas Recirculation (EGR) flow being out of the self-test range. Common causes include Faulty EGR Valve: The EGR valve may be stuck open or closed, causing improper flow, EGR Sensor Malfunction: The EGR sensor may be sending incorrect signals to the engine control module, Wiring Issues: Damaged or corroded wiring connections can disrupt communication within the EGR system. 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 P1407 Ford Description
The P1407 Ford code indicates that there is an issue with the Exhaust Gas Recirculation (EGR) flow being out of the self-test range. The EGR system is responsible for recirculating a portion of the exhaust gases back into the engine cylinders to reduce nitrogen oxide emissions. When the EGR flow is out of range, it can lead to poor engine performance, increased emissions, and potential damage to the engine components over time. This code typically signifies a problem with the EGR valve, EGR sensor, or the associated wiring.
Common Causes of P1407 Ford
- Faulty EGR Valve: The EGR valve may be stuck open or closed, causing improper flow.
- EGR Sensor Malfunction: The EGR sensor may be sending incorrect signals to the engine control module.
- Wiring Issues: Damaged or corroded wiring connections can disrupt communication within the EGR system.
- Carbon Build-Up: Excessive carbon deposits in the EGR system can obstruct flow and trigger the code.
- Vacuum Leaks: Leaks in the vacuum lines connected to the EGR system can lead to flow issues.
Symptoms of P1407 Ford
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the dashboard.
- Rough Idle: The engine may run rough at idle or exhibit unstable RPMs.
- Reduced Fuel Efficiency: A decrease in fuel efficiency may occur due to improper EGR flow.
- Engine Misfires: The engine may experience misfires or hesitation during acceleration.
- Increased Emissions: The vehicle may fail emissions tests or emit excessive pollutants.
How to Fix P1407 Ford
- Diagnose the Issue: Use a scan tool to retrieve the fault code and perform a thorough inspection of the EGR system components.
- Test EGR Valve: Check the EGR valve operation by applying vacuum and observing if it opens and closes properly.
- Inspect EGR Sensor: Test the EGR sensor for proper voltage and resistance readings to determine if it is functioning correctly.
- Clean or Replace Components: Clean out any carbon buildup in the EGR system or replace faulty components as needed.
- Reset ECU: Clear the fault code from the engine control unit (ECU) and test drive the vehicle to ensure the issue is resolved.
Cost to Fix P1407 Ford
The cost of repairing a P1407 Ford code can vary depending on the specific cause of the issue and the labor rates in your area. On average, you can expect to pay between $200 to $500 for parts and labor. Keep in mind that diagnostic time and labor rates can fluctuate, so it's recommended to obtain quotes from multiple auto repair shops to compare prices.
