Do you know what the code is? Have u had it reset? Try having it reset and whenn it comes back on see what the code is? I will do some checking on the code to see what it is. I know p stands for powertrain and the rest is what it is. I'll check and post back.

P0456 is a small evap leak. Most likely one of three things:

The start of your fuel cap failing (or just a bad seal)
Damage to the evap canister
A leak in the evap hoses

FYI, it is best to read codes with a reader. Apparently codes don't always show up through the "built-in" dash system.

P-0456 evap canister leak detected (.020). Check your evap canister to see if it got hung up on something. Also if ur off roading consider an evap skid plate or relocation. Its one of the first things to take a hit on a trail. Its low hanging on the driveline and will cause some serious problems. A skid costs around $100 relocation kits are cheaper and solve the problem of ground clearence. Search the forum for ways to fix the problem or you may be looking at a trip to the stealership.....
