check engine light comes on when gas tank level goes from near to full to about half. Often, removing and replacing the gas cap turns the ce light off.

Check engine light went on with a faint smell of gas coming through the vents when car was running idle. Was told I had "overfilled" the gas tank by the dealer mechanic. I do not "top off"my gas tank, nor did I accidentally overflow the tank.
