Code P0441 Scion 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 stabilized pressure is higher than [second reference pressure x 0.2], ECM determines that Purge Vacuum Switching Valve (VSV) is stuck open. If pressure does not return to near atmospheric pressure, ECM determines that purge VSV is stuck closed. The ECM illuminates the MIL and stores a Diagnostic Trouble Code (DTC) if this malfunction is detected in consecutive drive cycles.
