I got my first CEL with P0442, "Evaporative Emission Control System Leak Detected (small leak)." There was no "CHECK GAS CAP" message in the DIC and thus I thought it was something serious until I hooked up the scanner. It looks like my locking fuel cap CST 5903 is the culprit (it obviously couldn't be me). I wonder what would actually trigger the "CHECK GAS CAP" message.
