I have a 2003 Ford F-250 5.4L with the first $26 not passing. How do I get it to clear?

 

Any stored P-codes?

That just means all sensors have not achieved readiness. Were there any codes that you cleared? Did you recently disconnect the battery? It takes time to do the drive cycles to achieve readiness, then it will trip a CEL with a code. You should be able to see which sensors have not done this with a decent scanner.

Sounds like you have an issue with the evap system somewhere.

 

Ignore it. You're digging a hole where you don't understand what's under the surface, probably due to ambiguous (or wrong) software in an app.
