These are both trouble codes for the EVAP system. The EVAP system sucks gasoline fumes back into the engine to be burned up instead of realising the fumes into the air. The computer has detected both a small leak (P0442) and a large leak (P0455). First thing I'd do is make sure the gas cap is on securely. If it is, replace the gas cap, they're cheap. If that doesn't solve the problem you'll need a smoke test. Since your Impala is a 2006 model the leak triggering the check engine light may be so small that it can't be seen with the naked eye. A smoke test will reveal the leak. The shop will force harmless smoke into the gas tank then check the EVAP system lines going from the tank to the engine for smoke coming out. Once they see the smoke seeping out they've found the leak. HTH. -Jim
