P2401 2006 Toyota Camry Code - EVAP System Leak Detection Pump Control Circuit Low
Quick Answer
5 hours after the ignition switch is turned OFF, the electric vacuum pump creates negative pressure (vacuum) in the EVAP (Evaporative Emission) system. Common causes include Faulty Vacuum Pump Module, Vacuum Pump Module harness is open or shorted, Vacuum Pump Module circuit poor electrical 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.
