What does the p1407 code on a car mean?
What does the p1407 code on a car mean?
P1407 Meaning The Exhaust Gas Recirculation (EGR) system recirculates a portion of the exhaust gasses into the intake manifold under average vehicle driving conditions to reduce combustion temperatures and exhaust gas NOx content.
When to worry about an EGR valve problem?
If the initial reading is in spec but you have a trouble code for this system then it is possible that the system is not flowing when expected (EGR valve, EGR tube, DPFE hoses or control side issue), is flowing when it shouldn’t be (EGR valve or control side issue) or you may have an intermittent concern, possibly even with the DPFE sensor.
Why is there an EGR code on my Ford?
However, we often find EGR codes on Ford products caused by inexpensive plastic parts that falsely report position to the control module. Several technical service bulletins for a wide variety of different makes and models have documented different problems associated with the EGR valve system.
How much does it cost to fix a p1407 code?
The cost of diagnosing the P1407 code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.

What causes a failure code on an EGR system?
Another common problem causing failure codes in this system is that the tip of the valve will become irregular shaped from carbon deposits. When this happens it no longer creates a perfect seal. This can allow exhaust gas to continue to flow when not called for by the computer. An example would be at engine idle or when the vehicle is cold.

What should I do if my EGR valve is not working?
There should be no vacuum there at this time. If there is then check for proper EVR (EGR vacuum regulator) operation and vacuum line routing. Repair and continue testing. Hook up your hand vacuum pump to the EGR valve and slowly apply a vacuum. If the EGR valve is functioning then the engine should begin to run poorly and stumble.
