P0455 wtf
 

Hey all. I have a 2000 v70 with the p0455 large evap leak. I looked around for any obvious signs of a vacuum leak but I didnt see any. I replaced the gascap thinking ias good but its back. What do u think my next step should be?

Did you clear the code?

Yes but it. Comes back afftter a week or so.

Have you checked all of your hoses? Is the car running rough? We have to ask all the stupid questions because you have given very little info.

Yup totally agree with "RSPI", i had the same code, i noticed a line broken that runs to the air filter box. I replaced it and never saw it again, so just check all your lines for cracks, fitment, and if missing.
Good luck
