SOURCE: 2005chevy colorado check engine light on code code

This is an EVAP system code. There is a good chance that you just didn't put your gas cap on tight enough the last time you got gas. Check your gas cap and make sure it clicks at least two times after tightening it. If after doing this and driving for a while, the code doesn't go away, you will need to have further diagnosis done as another component in the evaporative emissions control system could have failed.

SOURCE: how to fix code po455 and po442 on chrysler

Hello and welcome. these codes are for a evap system leak, could be a gas cap, vent valve, purge valve, tank seal leaking, or any one of the fuel fuel vapor leaking. the only way to know for sure what part needs replaced is to have the system smoke tested with a evap test station.

The problem is most likely to be with your vacuum line they put cheap rubber hose for this purpose. You should find a diagram at the front of the vehicle trace the hoses by this diagram. You most likely will find a bad piece of hose.
