0442 - Evaporative Emission Control System Leak Detected (small leak)
You need to find out what is causing it. On my '00 GT it is the gasket where the filler neck goes into the tank.

okay thanks could it have anything to do with replacing the filler neck? about 2 months ago my mechanic put a new filler neck in cause my old was one rusted and leaking gas.

Could also pop up when you leave the gas cap open. I got the same code once, and it was my fuel filler neck grommet too.
