One reason why the check engine light might come on in a 2015 Chevy Trax is because the gas cap is loose or faulty. The gas cap, also known as the fuel filler cap, is a simple yet crucial part commonly found in most cars and trucks on the road. Its main function is to prevent dirt, debris, and dust from getting into the gas tank while ensuring a secure seal. It's worth noting that driving without your gas cap won't damage your engine or make you lose fuel. Modern cars have a flapper valve that prevents fuel from leaking out of the tank. Additionally, driving without your gas cap won't release harmful fumes into the passenger cabin.
