She no have a Gas Cap I lookey last nite !

 

Sounds like your filler flap is stuck open. Try spraying it with WD40 and then use the emergency funnel and push it in and out about 30 times. That could clean up the dirt that's causing it and lube the flap hinge.

The fix is in your owner's manual.

 

Try one of these:

 

count me in... check-engine light came on yesterday on my 2015 Lariat SCREW with the 2.7 EB - July 2015 build (at 11k miles)

took it to dealer and it's the fuel tank valve leaking fuel fumes. they didn't have any loaners so I'll take it back when they call and drop it off/ take the loaner. Repair/fix will take 1-2 business days. Seems a tad long ? But probably depends how many mechanics and bays they have open.

How long did it take with your trucks?

 

I think mine was in for a morning. No loaner but they gave me a ride to work.

thanks! i hope they get it done quicker than 2 days. with an open bay, the part available and mechanics dropping the gas tank and doing the fix + testing doesn't sound like a 2 day job

 

They told me to bring it in with as little gas in the tank as possible.

 

And then they'll return it all nice and topped off hopefully!

 

Have a '15 Lariat Super Crew that threw a P2450 EVAP system code @ approximately 13,850 miles. My F-150 was built 9 Sept. 2015. To resolve the issue, the TSB replaces the existing vapor pressure sensor/blocking valve along with the integral vapor tube. Since my Super Crew has a two piece drive shaft, the time required for the remediation is listed as 1.8 hours.

Bring a copy of the TSP to the dealer when you have the work done and show them what Ford states what the repair time is and not two days. It looks to me that Ford got from its contractor for the sensor/blocking valve either an unreliable product ( under designed) or that Ford specified an inadequate specifications for the sensor/blocking valve from their system analysis.
It appears that this issue is unique to the 2.7 L Ecoboost configuration.

Since I bought the truck, I am getting 20.9 mpg that includes 3 long hauls (566 miles total) with the largest U-haul trailer loaded with furniture and appliances.

 

Thanks ! After 4 days my engine light went off and has stayed off ever since. If it comes on again - I'll have them do it. If it stays off - even better.
