CEL code P0456

[Art Garcia]

I've read about this before and can't remembered what it is. What part needs to be replaced? Expensive?

That usually means a loose gas cap but here's a link to the other problem too.:haveabeer:

This code came up about two weeks ago. the lady at autozone said my gas cap was loose. the code came back up again yesterday. i dont think it is the gas cap. but i could start form there. could it be the pvc valve?

i will check the EVAP tube first. thanks for the link jerry. youre so helpful. always here for us. by the way your trac is looking good. ive seen your new changes

Also check all the tubes under the spare tire.



Everytime I fill up my truck I pull the rubber O-Ring up towards the top of te shaft and I haven't had any problems since doing this.



Thanks for the compliments.:haveabeer:

If you are talking about the hoses on the canistor. Just cut the tip ends off. Then reinstall, so it is tight.

They might have knocked it off durring shock replacement. Now it doest seal.
