2003 5.4 , Service Engine Soon light came on & stayed on.
Read a P0446 code (Evaporative Emission Control System Vent Control Circuit Malfunction)
not sure what to do next
anyone have had this, any insight how to address?
quick search of the Forum shows MrHam has a post on this, will look there

I run with no spare tire & wonder if that contributed
update: hmmm, this happened while pulling out of gas station after refueling. the gas cap says engine light may come on if gas cap not tightened correctly (see pic). i made sure the cap was on right, cleared code, and it's not coming back or pending .... yet (one minute of running).
It's possible thats all it was, but I'll wait and see before concluding.
