Three Most Common Causes of P0401 on Fords

In this video I'll share, by my experience, what has been the three most common causes of P0401 on Ford vehicles with a DPFE EGR system. The definition of P0401is "Exhaust Gas Recirculation flow insufficient". Its been my experience that this code is usually caused by a faulty DPFE sensor, clogged EGR ports in the intake, or damaged hoses going to the DPFE sensor.

Note: This video is not meant to be used for diagnostic purposes. I'm just sharing my experience about what has been the top 3 causes of this code on Ford vehicles with this EGR set up.

Let me know if you have questions. I'll be happy to help you with more information.
