Answer There are three parts to code checking on this year Ford, key on engine off, key on engine running, and continuos or memory codes. Code 11 is a pass code in any of these tests. If you did a KOEO test, after the 11 you should have got a 10, then another 11 or some other code. To help you I need to know if there is a code after the 10 separator code.
Typically a flashing CEL indicates a misfire bad enough to cause catalyst damage. How is the truck running?
