check engine light ...code P0456

Evap leak code check your gas cap make sure it is tight.

It will take a few starts before the code disappears.

Was it loose when you checked it??

Well the code is for your evaporative emission system and may take a day or so to clear if the cap was not sealed properly the next step would be a new gas cap or if its under warranty take it to the dealer. But I would give it a day or so.

gas tank cap closed tight?

gas tank cap closed tight?

Did you even read the thred??

my bad...missed your one comment.

I thought you mentioed something else.

I'm tired, been up since 3am.

Sometimes it can take 40-50 cycles before it goes away. Do you live near anyone who has a code reader? They can reset it for you,then see if it comes back on.

have u done any work to it recently?
when u got back from GW did u wash the engine bay with a pressure washer ?

it the jeep still under warranty ?

in the passenger rear wheel well area
is the wheel well liner in tack ?
thats where the evap canister is located

gonna have to trace all the lines from the avap canister to the gas tank and in the engine bay
one might of have gotten damaged at GW or damaged when u pressure washed it
or u could take it to a shop that has a tank smoker to check for leaks

i would start at the evap canister myself
tracing the lines and checking all connections
sine the code u got is for a
"small leak "
it may be a pin hole in the line somewhere

good luck
