What does jeep wrangler p0456’ mean? I saw this code on my Jeep Wrangler and I’m not sure what it indicates. Can anyone explain it in simple terms and suggest how to fix it if there’s an issue?

The code P0456 on your Jeep Wrangler indicates a small evaporative emissions leak. This means there’s a minor issue with the fuel vapor system, possibly due to a loose gas cap or a small leak in the system. To fix it, start by checking the gas cap for proper tightness. If that doesn’t resolve it, you may need to inspect the vapor hoses and connections for leaks or damage.
