P1451 Mercury Code - EVAP Control System Canister Vent Solenoid Circuit Malfunction
Quick Answer
The Powertrain Control Module (PCM) monitors the Canister Vent (CV) solenoid circuit for an electrical failure. Common causes include Faulty Canister Vent Solenoid, Canister Vent Solenoid harness is open or shorted, Canister Vent Solenoid electrical circuit poor connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
