P1451 · FordEVAP Control System Canister Vent Solenoid Circuit Malfunction

P1451 on Ford vehicles means the powertrain control module (PCM) has detected an electrical fault in the canister vent solenoid circuit, which is part of the evaporative emission (EVAP) control system. The PCM monitors the vent solenoid's command and feedback circuits and sets this code when the voltage or current falls outside the expected range, indicating an open, short, or excessive resistance in the solenoid or its wiring.
