    How To Diagnose and Clear the Code P0441?

    Performing a diagnostics check with a diagnostic scanner helps you identify a particular problem area that is outside the normal range and shows where a fault might be occurring. This helps you to detect errors before they cause more damage to your vehicle. In comparison to generic OBD devices that only provide OBD-level engine-related data, Carly can run advanced manufacturer-level diagnostics, check all your ECUs in your car (like ABS, airbag, multimedia) and get deeper insights. You can find additional information about the trouble code and understand the severity of the problem. With the new Smart Mechanic feature, you get additional professional insights and tips from expert mechanics. You are able to check components and their mechanics, find detailed repair tips, and learn about potential future damage. After you have fixed the problem you can easily clear the fault codes with Carly, too. Also, the diagnostic results are safely stored inside the app or as convenient PDF reports you can share with your friends or a mechanic.

    How the tank vent valve works

    The tank venting system captures evaporated components of the fuel and feeds the components into the combustion process. On the one hand, it prevents hydrocarbons from escaping into the environment. The fuel expands and thus promotes evaporation. However, at constant pressure and temperature, evaporation decreases over time, because only the light hydrocarbons evaporate. On the other hand, the tank venting system avoids a vacuum in the tank when the fuel is removed. Therefore, a ventilation system is installed at the rear of the tank. The tank vent valve controls the regeneration of the activated carbon filter by purge air. The purge air is drawn through the activated carbon filter and hydrocarbon (HC) is enriched. The amount of enrichment depends on the HC loading of the activated carbon. The purge air is then fed to the engine for combustion.

    *Every car is unique. The Carly Features that your car supports depend on the model, build year, hardware, and software in the car. Plug the scanner in the OBD2 port, connect to the app, run your first diagnostics, and check which features are available for your car.
