I have a 2013 F150 ECOboost and I keep getting DTC code po13b. I took it to the dealer and they said it was po114 but my reader say po13b. Not sure why the difference. They did a flash of the computer which turned the check engine light off for about 3 days, now it is back on, same code. Any thoughts?

 

Take it back and if they can't fix it, find a dealer who can.

 

Update. Took the truck back into the dealer, they replaced a tcip sensor that had gone bad. Not sure what that is but it seems to have done the trick.
