Code P0456

P0456 is an OBD-II generic code that indicates a small EVAP system leak has been detected. This code is for the evaporative emissions (EVAP) system, which captures fuel vapors from the gasoline tank and prevents them from entering the atmosphere. When the engine control module (ECM) detects a small leak in the EVAP system, it will set this code and illuminate the Check Engine Light. Symptoms of this code may include a strong gasoline odor from the vehicle, difficulty starting or running, or an illuminated Check Engine Light.

The most common cause of this code is a loose or faulty gas cap, but other causes may include a faulty fuel tank pressure sensor, broken or damaged hoses, faulty canister purge valve, or a damaged evaporative emission canister. To properly diagnose this code, it is important to visually inspect all parts of the EVAP system for damage and to check for loose connections. It is also important to perform any tests recommended by your vehicles manufacturer.
