P043F 2013 Toyota RAV4 Code - Evaporative Emission System Reference Orifice High Flow

Quick Answer

5 hours after the ignition switch is turned off, the leak detection pump creates negative pressure (vacuum) in the Evaporative Emission (EVAP) system. Common causes include Faulty Canister Pump Module, Canister Pump Module harness is open or shorted, Canister 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.

Code P043F 2013 Toyota RAV4 Description

5 hours after the ignition switch is turned off, the leak detection pump creates negative pressure (vacuum) in the Evaporative Emission (EVAP) system. The Engine Control Module (ECM) monitors for leaks and actuator malfunctions based on the EVAP pressure. The leak detection pump creates negative pressure through the reference orifice. When the system is normal, the EVAP pressure is between 97 to 100 kPa(abs) [726 to 750 mmHg(abs) (Typical value)] and saturated within a minute. If not, the ECM interprets this as a malfunction. The ECM illuminates the MIL and stores a Diagnostic Trouble Code (DTC) if this malfunction is detected in consecutive drive cycles. The Canister Pump Module is attached to the EVAP Canister and contains the Canister Pressure Sensor, the Leak Detection Pump, and the Vent Valve.
