There are several issues that would cause you Check Engine Light to come on and a few of those have simple solutions. In some instances, if you do not turn your gas cap completely closed once you’ve filled up your tank, it will register as open in your vehicle’s computer and it will turn on the Check Engine Light to warn you to close it. If left open, your gas gap may release gasoline vapors into the atmosphere. Your vehicle wants the engine to be a sealed and closed environment. At the other end of possibilities, that light could mean any number of more serious engine issues. If your on-board diagnostic systems detect any problem with your powertrain, meaning any part of your vehicle related to the engine and transmission, it will turn on this light as a warning to bring your vehicle in for service. At Advanced Tech Service Center, we use the latest in advanced diagnostic testing equipment to read your vehicle’s status and determine the issues.
