    • It seems like you've disconnected the battery and replaced the air flow sensor, but the warning lights are still on. This could be due to a variety of reasons. Here's what you can try:

      1. Reset the System: Sometimes, the warning lights need to be manually reset. Consult your owner's manual for the specific procedure for your model, or you may need a professional scan tool to reset the system.

      2. Check for Proper Installation: Ensure that the air flow sensor and any other components you've handled are properly installed and connected. A loose connection could trigger the warning lights.

      3. Inspect for Other Issues: The warning lights might be related to another issue in the vehicle. A professional diagnostic scan can reveal any stored error codes and pinpoint the problem.

      4. Consult a Professional: If you've tried the above steps and the lights are still on, it would be best to take your Prius to a Toyota dealership or a professional mechanic specializing in hybrid vehicles. They have the proper tools and expertise to diagnose and fix the issue.

      Remember, while online advice can be helpful, it's always best to consult with a professional who can physically inspect your vehicle, as they can provide the most accurate diagnosis and solution.
