I have also changed the diesel filter and cleaned the tank to eradicate any water in the fuel. THIS IS DRIVING ME NUTS CAN ANYONE HELP THAT MAY HAVE HAD THIS PROBLEM AND SOLVED IT , every time I clear the code it comes back up before I even start it, there is someone who nos how to fix this, they just need to share the knowlage lol
