Code P1456

Hello,

This is leak in your EVAP system. It could be as simple as a loose gas cap, or it could be something a little more serious like a split in a hose or something along those lines. To be sure about what is setting this Direct Trouble Code (DTC), I have included in the diagrams down below a troubleshooting guide that will take you step by step in tracking down and finding the cause of the DTC so you can fix it, and fix it right the first time.
Please go through the guide and get back to us with what you are able to find out.

Thanks,
Alex
