P0441 2014 Toyota RAV4 Code - Evaporative Emission Control System Incorrect Purge 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 Loose or missing gas cap, Faulty Purge Vacuum Switching Valve (VSV), Purge Vacuum Switching Valve harness is open or shorted. 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 P0441 2014 Toyota RAV4 Description
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.
