P0440 S90-V90

Hey Guys,

What are some common problems with the evap system on the s90 that would throw this code.

Thanks,

    We had an identical problem on 98 V-90 (throwing 440 codes) and it turned out to be the evap emissions control valve. Has been repaired for 3 months and not a single code thrown. Good luck.

    I switched the gas cap and still got cel a few days after. I didn't think its the cap because when im really low on gas there is a loud hissing sound when it releases pressure. What to check next??

      Check the hoses to evap canaster , they are small conection hoses that are two different,
      sizes also check hoses that go into hose tree drivers side mid point of engine.
      Lots of hoses etc associated with this evap system , I have had good luck doing a smoke test
      Good luck
