Some Scion xD owners report experiencing persistent issues with the emissions system when the check engine and VSC lights are illuminated, accompanied by diagnostic codes such as P2401, P043E, P043F, P2402, and P2419 after replacing the EVAP canister kit and purge valve. These issues may manifest as a Check Engine Light signaling problems with the evaporative emission system and a blinking VSC off light indicating stability control concerns. Potential causes include faults in the EVAP control circuit, particularly with the leak detection pump, as well as problems related to the evaporative emission system components. Owners are advised to inspect the EVAP system lines for disconnections or damage and check the charcoal canister for leaks or malfunctions. Clearing the diagnostic trouble codes after addressing the root cause is crucial for monitoring any recurring issues. If problems persist, seeking assistance from a certified mechanic or dealership is recommended to ensure proper diagnosis and repair. Prompt attention to these diagnostic codes is essential for maintaining the performance and efficiency of the vehicle's emissions system.
