Error Code - P0455 Causes?

[darrahc]

I'm over in Sweden and got a P0455 error code - EVAP leak monitor large leak detected. It seems like the most probable cause is the gas cap but wanted to check and see if there is anything else I should look for.

Thanks in advance for any help/suggestions.

If it's an old car the evaporative emissions hoses might be rotting out. That happened on my Durango with 100,000 miles on it.

I'm pretty sure that's the code I have. Mine is a crimped evap line up near the cross member, near the frame.
