Hello all. I have a 2018 2.7 STX Super Crew. My check engine light turns on often. When I connect my OBD-II no codes are detected. I looked up the link issue and it seems it's an evap leak from the gas filler neck. I followed the tips from this video: https://youtu.be/JlK2qekqX5s and nothing had changed. Anyone else have the same problem and does anyone know what I can do?

 

I had a similar issue. Took a rag and some all purpose cleaner. Wipen the flap and around the neck,hoping that itdmall debris stopping the seal.
Have not had a problem since.

 

I'm confused. If you are not able to pull a code, you are just guessing on a fix. These vehicles keep a history of past issues, so even if the light is off, the past issue should still be readable.

I suggest trying another scanner. Forscan is my recommendation.
