What do I do if the Check Fuel Cap message appears?
Your car is equipped with a pretty sophisticated evap/emissions system that monitors the level of pressure in the gas tank. This is done to detect possible leaks, including a loose gas cap. If you’ve left the cap loose (or off), the Check Fuel Cap message will show up on your dash. To handle the situation, follow these steps:
Turn off the engine.
Open the fuel door.
Double check the gas cap and tighten if necessary.
Crank the car and drive normally.
The light should go off within a few days. If it doesn’t, the code will need to be checked.
If the light doesn’t go off, it could mean there is a leak in your system, or the cap is bad.
