It is an emission leak. I had that and P0456 pop up at the same time. Bought a new lockable gas cap from a locale parts store. Same problem. Bought a new one from Dodge dealer...problem fixed. No idea why but I have since heard that only OEM caps will solve the problem. Probably because the cost twice as much! :( Emission leak. I got the same code. Replace gas cap with new one from DEALER and it should fix the problem. I made the mistake of getting a new locking one from Checker Auto Parts. Apparently they do not work. You could also have a crack in any of the vaccuum and emission hases between the tank and the engine. The canister(about 2 feet in front of tank) and the purge solenoid(behind battery) are normal places for cracks.
What else can I help you with?
What is Error code p0456 on a 2003 Dodge Durango?
Error code P0456 on a 2003 Dodge Durango indicates a small leak in the evaporative emission control system (EVAP). This system captures fuel vapors from the fuel tank and prevents them from escaping into the atmosphere. A small leak could be caused by a loose or damaged gas cap, cracked hoses, or faulty components within the EVAP system. It's important to diagnose and address the issue to avoid potential emissions problems and ensure optimal vehicle performance.
