P043E 2011 Toyota Camry Code - Evaporative Emission System Leak Detection Reference Orifice Low Flow
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 Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.
