The engine light can mean a long list of things, from something as trivial as a gas cap that has been improperly placed back on after refueling to more serious problems like misfiring or an improper fuel mixture. The check engine light is the single most intimidating alert to pop up on the dash, except for the low fuel light, that always seems to pop up as soon as you pass the last gas station for miles. So when you see a symbol light up, first address what the problem is and then its severity based on its color. Green (and sometimes blue) lights are the least stressful and may mean that a system is on or they’re reminders to buckle up or that one of the doors isn’t closed all the way. There are a combination of yellow and orange lights that will pop up every once in a while, and these are usually less urgent, but still important to address. The red lights usually indicate the more serious issues that you’ll want to tend to immediately, if possible. Maybe you have noticed over the years-or maybe you haven’t paid that close attention-that the colors of the indicator lights vary. While not each and every light is explained here, some of the most common and troubling dash indicators have been expanded upon to help with understanding what your truck is telling you. So when your dash starts lighting up like a Christmas tree, you’ll have a better grip on what your truck is trying to communicate to you through all the bright symbols and indicators. With increased on-board functions and safety features, there are bound to be more problems with all those factory-installed bells and whistles. Others, especially the ones that correspond to more modern conveniences, can be a little trickier to understand. Some of them are familiar since they haven’t changed much over the years and actually make visual sense at first glance.

If you haven’t taken a good look at your gauges and examined all of the symbols, they can be a bit confusing and read like some weird alien language it must be tough to create a single symbol that represents a major system of your truck. Instead of sweeping the problem under the rug, understand why the lights on your later model Chevy and Ford truck’s dash are illuminating and what the heck the lights even mean.

They are great for helping pinpoint the exact code or problem that makes the dash light pop up, but they should be used as diagnostic tools and not as an off switch. Code scanners are extremely helpful-don’t get us wrong. With the ability to plug in a code scanner and “clear” trouble lights, a lot of truck owners think that turning a light off cures whatever is going wrong underneath the hood or anywhere else that could pose a problem from bumper to bumper. “Out of sight, out of mind” is an all-too-familiar “fix” for dash lights. Let that last point sink in, and let’s keep rollin’. But before you start sweating and stressing out, just take a deep breath, and remember-these trouble lights are meant to give you the soonest heads up of an issue that could have a simple, inexpensive solution IF addressed in a timely manner and not left to worsen over time. Usually, when the check engine light pops up out of nowhere, the natural next symbol that comes to mind is “$”. Aside from running low on fuel or air pressure in the tires triggering an alert, there may or may not be much to worry about. Nothing can ruin an enjoyable cruise faster than the surprise illumination of dash warning lights. What Some Warning Lights & Engine Codes Really Mean
