Code P0456 indicates a small leak detected in the Evaporative Emissions (EVAP) system. The evaporative emissions (EVAP) system is designed to prevent fuel vapors from escaping into the atmosphere.

Can a vehicle pass smog with check engine light on?
During your drive, maybe even as soon as you start the engine, your vehicle realizes an emissions fault, and turns on the Check Engine or Service Engine Soon light. No check engine light, but no chance of passing the emissions test either. However, you will not know this until your vehicle is smog tested.
