Anybody throw a P0456 code?

NotQuiteRight · 11-13-2012, 05:10 PM

Did some searching on the code only to find lots of generic info. I can't seem to find any specifics on what exactly could be wrong. Anybody here go through this yet? P0456 Code

is it an evap system slow leak code?

If so, start with checking the fuel cap and o-ring.

Yes thats the one.

I checked the gas cap and cleared the code... Is that a common thing for the gas cap to throw a CEL?

Yes, if it's not tightened it should eventually throw a fault for it.
