Code P2419 2006 Scion xB 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).
