OBD Trouble Code: P1451 EVAP Control System Canister Vent Solenoid Circuit Malfunction
And I always make sure the gascap clicks when they are tightened and the o-ring is not cracked or broken.I always start there with evap codes.Bad gas caps most always cause evap codes

It is an electrical fault for the vent solenoid circuit. Check for damaged/corroded wiring to the solenoid.
