Gas Cap Light coming on intermittently-why?

[jmg]

Hi! My wife just informed me that a Check Gas Cap light is coming on intermittently on her 2006 Taurus. The gas cap was replaced about 2 yrs. ago with an orig. equip. one from Ford. This problem apparently started a couple of months ago, but I just found out about it, right as she was just leaving to take her mother to the hospital. Apparently no drivability issues when it happens-so far, I hope. Any ideas? Guess light doesn't go off right away if she takes off the cap and re-tightens it. Thanks for any ideas or thoughts. Happy Thanksgiving to everyone. Be Safe!

Leaning on the gas handle while filling leads to oblonging the filler neck area where the gas cap goes. A new cap will fix the issue for a while. Otherwise a filler neck will be needs.

The PCM is seeing a larger evap look and assumes the gas cap is the problem. It could also be other EVAP components that are bad.

It happened to me on a Chevy and searched online and was suggested to apply oil to the rubber seal on the gas cap. By dipping one's finger in oil and then spreading it on. Only had to do it once.

Thanks for the suggestion. Will try it tomorrow. If it doesn't work, will have to dig deeper.
