P043F Honda Code - Evaporative Emission Leak Check Module Standard Pressure High
Quick Answer
The Powertrain Control Module (PCM) starts the Evaporative Emission (EVAP) system diagnosis after the vehicle has been turned to the OFF (LOCK) mode and has met all other enable conditions (initial engine coolant temperature [ECT SENSOR 1] and off for at least 5 hours). Common causes include Faulty Vacuum Pump, Faulty Vacuum Pump (Motor), Faulty Control Valve. 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.
