Expedition: I had the check engine light checked at autozone

Customer Question

Hi I had the check engine light checked at autozone and no codes came up. Also at Midas. They couldn't figure it out either. But pep boys is saying p1405. Is this something I can fix myself?

Still there?
Expert:  Ron replied 1 year ago.
Okay, thank you, ***** ***** P1405 is set in most cases due to a failing DPFE ( Differential Pressure Feedback EGR Sensor ) and in most cases replacing it will solve this code. Start first with making sure both hose are connected to it and if so I have enclosed the location as well as a quick test you can perform on it to verify if it has in fact failed. Copy and paste the link below to your browser to open and view them. One are the test steps and the other is replacement steps.https://dl.dropboxusercontent.com/u/104923897/DPFE%20loc%20Apr%201.pdfhttps://dl.dropboxusercontent.com/u/104923897/DPFE%20Apr%201.pdf
