I have an 05 standard cobalt, - This the oxygen sensor before the cat. converter or after the cat. converter? How do I know which O2 sensor this is and do i need a special socket tool for the job? Also can I buy the part NTK Oxygen Sensor Part No. 21546 from Advanced auto to fix this problem?

Also, what does code P0455 Evaporative Emissions system leak detected, gross leak no flow mean?

Is that the EVAP Valve or canister, or both?
