Thank you for using just answer.My name is XXXXX XXXXX i will try to assist you.
The codes you have for your truck is for the egrtp sensor.It is either getting to much
voltage or there is a open in sensor.The sensor is located in the front of the intake under
the elbow.Replace the sensor and it should take care of problem.Also while under hood
remove egr valve and see if its clogged up.If so clean it.
is that sensor a dealor part or can i get it at a local part store?
I think the sensor can be bought anywhere but with the powerstroke i would only put ford parts on
