To reset the computer. disconnect the battery ground cable, turn the ignition key to start for a few seconds and hook the cable back up. Do not have the ignition switch on while unhooking or hooking up the cable. That will reset the light. If the problem persists check all the vacuum hoses going to the vacuum canister mounted under the driver's door on the frame.

Yup, P0456 is an evaporative emissions control code. The computer will check to see if the problem is still there over the next several starting cycles (turning on the engine). If so, the MIL stays lit, if not it turns off.
If you always tighten your gas cap at least 3 clicks and you're still getting the code, time to get a new cap.

Turn your key on but don't start the truck. Hit your gas pedal three times. Shut the key off and this should reset your computer.

a small leak in the evap system is most likely the cause..
there are numerous small hoses in the vent system.. the vapor canister is mounted under the cab. check all the hoses for cracks especially around the clamps... good luck
