I also updated the spreadsheet today to include a new tab at the bottom titled "Unsuccessful Codes. I've done quite a bit of searching and reviewing of other spreadsheets and codes for other vehicles including the F150, Fusion, Flex and SuperDuty. From those spreadsheets, I found common codes and tried them on the Expedition. In this new tab is a list of all the unsuccessful codes I have tried:

If anyone else has tried unsuccessful codes and wants me to add them to the sheet, just let me know. This way we can save others the headache should they think to try them!
