DTC P1457: EVAP Control System Leakage (EVAP canister system)
The EVAP system has to be checked for leak. It can have a very small leak which can't be diagnosed without a special diag. tools, like a smoke machine.
It's not something that a DIY guy could diagnose at home. The only thing that you can do probably is to check the fuel filler cap and make sure it's tight, the seal ring isn't cracked or missing - beside that you will need a help of a shop.
