  • P0456 - EVAP Leak

    My car threw this code a couple weeks ago. I cleared the code and it stayed off for about a week. It came back again.

    Tried the tricks of putting some grease on the gas cap seal, didn't help. Saw videos online replacing he EVAP leak detector pump etc.

    I decided to try the cheapest solution first, replace the gas cap. This fixed it. (Yes I tried tightening it a few times, no luck before the grease).


    The aftermarket cap that fits, and, has a tighter seal (at least on my car), is: https://www.amazon.ca/gp/product/B00...?ie=UTF8&psc=1

    Make: GATES
    Model: 31838



    Just wanted to throw this out there for anyone else having the same issue at around 98,000kms.

    Make sure you hear three clicks, otherwise, you might get some more leaks.

      I'll do 4 clicks and 2 jumping jacks just to make sure.

        Yeah the grease trick doesn't work if the problem is the valve in the gas cap - guessing that was your problem here.
