Que es el Codigo p0456 de mi jeep commander 2007

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your Jeep Commander. The P0456 code indicates a small leak in the EVAP (Evaporative Emission Control) system. This system traps fuel vapors from the gas tank to prevent them from escaping into the atmosphere. Common culprits include a loose or damaged gas cap, a faulty purge or vent valve, or a cracked hose in the EVAP system. Since the issue gets worse in the cold, it could mean the components or seals are contracting and leaking under those conditions. A smoke test is usually the most effective method for pinpointing the exact cause, as it can reveal even the most minor leaks in the system. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered.
