Default Hyundai Elantra 2003 Engine Code P0455?

Hi, this code just came up on my car which is a large leak in the Evap. System of the car. I just had 2 O2 sensors changed last week. In November I had a hole in my exhaust system and needed a new flex pipe put in. Last week when I had the O2 sensors put in I asked if they saw anything that I should look at and they said no. I just tightened my gas cap. But what else could it be. Also in November I had a new Power Steeing hose put in. Thoughts? Should I bring it to the garage.

Common problems to cause this might be worn/cracked/leaking emission and vacuum hoses, a hole or disconnect in the filler next, improper seal around the fuel pump access hatch.. the easiest thing would be to have a shop test it. They can run a pressure check and hopefully determine the cause of the leak.

I meant a garage or shop. Actually, a dealer (as was pointed out to me here recently) might be the only ones with the equipment to pressure test it. Otherwise, you could look for any obvious problems like I mentioned above.

Dealer can plug in GDS and force EVAP system to do a self test and verify repair attempt.
