Scion xD persistent evap leak issue with code P0441 after replacing purge valve solenoid and gas cap on Scion xD

Some Scion xD owners report experiencing persistent EVAP leak issues, often indicated by the P0441 trouble code, even after replacing the purge valve solenoid and gas cap. These owners note that a loose or faulty gas cap can still trigger the code, necessitating a thorough check to ensure it is properly tightened and functioning. Additionally, some have found that inspecting the EVAP system hoses for cracks or disconnections is crucial, as these can contribute to leaks. Vacuum leaks are also a common concern, prompting owners to conduct a comprehensive inspection of the system. Furthermore, blockage in the charcoal canister has been identified as a potential cause of the persistent leak, warranting examination for any obstructions. Utilizing a scan tool for diagnostic procedures is recommended to investigate further, including testing the purge valve, fuel cap, and charcoal canister, as well as checking for vacuum leaks. Addressing these factors systematically can help resolve the ongoing EVAP leak problem.
