P0442 means you have a small leak in your EVAP System. your can try replacing the Gas cap since it's the easiest thing to do and reset the check engine light with a scanner. If the check engine light came back on then your going to have to go though all the Vacuum line in the EVAP system and connections. The other thing too is the service engine light should turn off when the problem is addressed and it may take up to three start ups to clear. Good luck and keep me posted, be glad to help, Recap, change the gas cap and inspect all the hose and connection's to the EVAP system.
