I had hooked up my diagnostic tool to my truck, to find out why mt check engine light was on. The code p0456 came up and it said evaporative emission system leak detected, very small amount. Now I trying to figure out where to look for this leak and how to reset the compter to get the engine light off in my dash.

Do not reset anything as the freeze frame data is there to show when and all the readings when the failure occured.

You need a smoke machine, scan tool and a voltmeter to determine the failure. It is not as easy as you think.
