it gets re set after a repair is performed. if you clear it now, yo will wipe out the freeze frame data that the tech needs to see when the failure occured. Roy

Mine came on and the short answer was I had a habit of topping off my fuel. This causes the charcoal in the canister assy to raise up and clog the fuel while passing. It can also be caused from a worn out gas cap, which is supposed to be checked at 60xxx mi. I replaced my cap, put fuel additive into my tank and the light went off after 2 days. You can do this, after 2 days disconnect the battery cables for 5 minues, then reconnect them. if the light comes back on you should have it checked out. a canister was estimated to cost $350.

Hello, Disconnect the battery cables completely for a few minutes. WARNING: you will loose all radio setting and seat settings as well as DELETE all engine codes. p.s. I am no expert but I did this and it worked and I lost engine codes.
