Europarts has the Purge Solenoid (ELCD) for $62. The system using vaccuum from that throttle body hose to create a vacuum in the fuel tank. It does this to test for leaks and uses a sensor on top of the tank to test for the vacuum.
The P0455 code is part of the OBDII Emissions system check. When certain criteria are met the ECU pressurizes the fuel tank/system by opening the purge valve and closing the cannister close valve near the right rear tire. If your tank can't hold a vaccuum it assumes you have a hole somewhere in the system and throws the code after it fails the test. It probably throws the code when you're idling.
