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.

I would have him take a look and make sure that there is no problem there.

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.
