2001 SE Maxima AT ~ 29,000 miles
I turned on the car again after a 20 minute trip and SES light comes on. Went to an Autozone and they found 4 codes (2 seperate codes but 2 of each):

(2) P0455: The PCM has determined that a large leak exists in the evaporative emission control system

(2) P1448: ELC System 2 Fault

The car seems to run fine, no loss in power or any roughness or rough idle noticed. Can you guys give me any advice about what the problem may be before the dealer keeps my car for a few days? I especially have no idea what the second one is.

Thank you in advance- any advice would be very appreciated.

Make sure your gas cap is tight
Sounds funny but i had this problem B4 and paid 65$ for the service.. Make sure its 3 clicks tight

I've checked the gas cap, actually that's the first thing I did. Does anyone know what could cause these codes, especially the second? Thanks.

i dont have a definition for 0455 but 1448 is evap canister vent control valve open. ive never had or helped anyone with this code but i would imagine if the valve was closed it could be cleaned but i woudlnt know what to do since its saying it is stuck open. ive read in the 4th gen FAQ about the evap canister cleaning so you may want to start there.
