The P0456 code for a PT Cruiser indicates a small leak in the evaporative emission control system (EVAP). This system captures fuel vapors from the gas tank and prevents them from escaping into the atmosphere. A small leak could be due to issues like a loose or damaged gas cap, cracked hoses, or malfunctioning valves. It's important to address this issue to maintain fuel efficiency and reduce emissions.
