My 2004 XC90 is throwing a P0455 code (Emission, detected Large Leak) I also get the "gas cap loose" message on the dash prior to getting the 0455 code. I have replaced the Gas cap twice and the last one came from Volvo just last week. I have removed the spare tire and hoses from the charcoal filter all seem to be in good condition including the J-hose. I replaced the evap purge valve and related hoses recently due a different code. Can someone suggest where to look next without spending the money on a smoke test?

Time for smoke test.
