Worn cap set off my engine check light also. Suspect the rubber seal.
I changed the gas cap, and then they took out and swapped the whole fuel system. The light is still coming on due to this matter.
Gas cap was exchange to get light to go off. Warning continued for several weeks and then inadvertently went out.
