did you recently fill up with gas? Sometimes the code is caused because the gas cap is not on tightly otherwise P0442 is refered to as a technicians nightmare, unless you use a smoke machine. There are a several valves involved, the canister and miles of hose.
Good luck!! And post back with any results

That is a small leak. your going to need a smoke machine and a scan tool to close both vents (canister purge and vent valves). Time to take it to a shop!! BTW, with a smoke machine and scan tool, there is no nightmare. It's actually fairly easy. just a matter of connecting the smoke, closing the valves, and finding where the smoke leaks out.....

My nephew's Explorer has thrown this code (P0442). We used AE to perform a running EVAP leakdown test and it passed. I suppose this means we should change the fuel filler cap?
