P2419 2007 Toyota Highlander Code - Evaporative Emission System Switching Valve Control Circuit Low

Quick Answer

When 5 hours have elapsed after the ignition switch is turned OFF, the electric vacuum pump creates negative pressure (vacuum) in Evaporative Emission (EVAP) 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.

Code P2419 2007 Toyota Highlander Description

When 5 hours have elapsed after the ignition switch is turned OFF, the electric vacuum pump creates negative pressure (vacuum) in Evaporative Emission (EVAP) system. Then Engine Control Module (ECM) monitors for leaks and actuator malfunctions based on EVAP pressure. The ECM determines that the vent valve is stuck ON (closed) if 1) the pressure is higher than -7.5 mmHg (-1 kPa) or lower than -33.75 mmHg (-4.5 kPa), and 2) the EVAP system pressure does not stabilize for a duration of 60 seconds. The ECM illuminates the MIL and sets a Diagnostic Trouble Code (DTC).
