2010 w/ P1450 fuel tnk vacuum code
Good morning. I've got a 4.6L 3V 2010 STX F150 w/ P1450 check engine code- fuel tank vacuum cannot bleed. Out of warranty at 42,000 miles. Hoping to save the dealer diagnostic & repair charges if possible. Pulled up some info from the forum on a 2000 expedition with the same issue. Not sure how to troubleshoot the "no fuel cap" filler assy for no vacuum relief and the fuel tank pressure sensor. Surprised as heck to have an issue like this with such a new vehicle. Any info/ advice would be appreciated.
