It is important to note that while the check engine light can sometimes indicate a minor issue, it can also indicate a more serious problem. If the light remains illuminated or if you notice any other unusual symptoms with your vehicle, it is recommended to have it inspected by a qualified mechanic to diagnose and address the underlying issue.
