Solution 1: The Gas Cap
Open up your gas tank and inspect the condition of the cap. First, spray clean the gas tank with a WD-40 cleaner and check if the gas cap is dirty. If it is, use the WD-40 cleaner to wipe it clean. If the cap is damaged, replace it with the correct model gas cap.
Solution 2: The Canister Purge Valve
The canister purge valve is usually located behind the intake, right next to the throttle body. Check this component in your car while the engine is still running. Place your finger at the vacuum port to check its functionality. If your finger experiences vacuum suction, it means the canister purge valve is stuck and needs to be replaced. Simply take off the used canister purge valve and replace it with the correct new one.
