How do you fix the CEL light or check for air on a Ford Explorer 2012? CEL lights comes on gas tank was not closed tightly?

Asked by Aug 03, 2016 at 11:39 AM about the 2012 Ford Explorer XLT 4WD

Question type: Maintenance & Repair

I am pretty sure the problem may be my not closing the cap carefully and completely.  I've only put gas in three to four times. Previously there was no problem. Now, I noticed, it was slightly open this morning after filling the tank yesterday and thinking I had closed it properly/tightly.  What should I do besides the obvious, check the cap carefully each time.

After refueling give the cap a couple of extra twists.

Thank you, but It does not have a twistable gas cap.

The fuel cap on these is very critical about getting it on correctly, my neighbor is always telling the fuel attendants to make sure it is on correctly, no self serve here. He finally just picked one station to get all his fuel and they get it right everytime. You may want to buy one of those little cheap code readers and if you mess up you can just clear the code yourself, plus it might just be handy to have, you never know these days.

Ah ha it has capless fuel filler. Then that is pretty simple, open the fuel door, insert pump nozzle, fuel, remove nozzle and close the fuel door. How in the world could anyone mess that up?

Thank you Tennisshoes, your answer was very "helpful" and considerate, not antagonistic or belittling without the full details or considering "malfunction".

Remember: Newer vehicles are not allowed to allowed to emit gasoline fumes into the air. The little door could be defective, allowing air into the system. This could cause a CEL. Also, when fueling, DO NOT force feed gas into the tank after it clicks off the first time. Doing so will force liquid gasoline into line going to the charcoal filter, destroying it. It could also damage the EVAP solenoid pump. On my F 150 the pump is located on the top of the intake manifold.

Thank you, OJ. We have made an appointment to check the door to see if it is defective.
