Question about 2003 Mitsubishi Montero Sport
The definition for P0456 is: Evaporative Emission System Leak Detected (very small leak). Check all your vacuum lines especially around the canister and check the gas cap on the vehicle for a good seal and make sure it is on good. I hope this helps you and good luck.
