What Does it Mean When the Check Engine Light Illuminates?
That pesky light on your dashboard. It illuminates, and you wonder what the check engine light means. Should you be concerned? The answer is yes. This is not your maintenance or service needed light, which indicates you are due for routine service. Instead, the check engine light means there is a potential problem that your vehicle’s diagnostic system has detected. The problem may impact your vehicle’s emissions, exhaust, or fuel systems, and may mean that your car, truck, or SUV is emitting pollutants at levels higher than those allowed by the government. What you shouldn’t do when it comes on, is ignore it. This could lead to unsafe conditions or costly repairs, which is especially true if your light is flashing. This signals a larger issue that needs to be dealt with immediately.
