Check Engine Lights
If your check engine light (also known as the malfunction indicator light, or MIL) has come on, it means your car is telling you something's not quite right, and you need to, well, check the engine. These lights are very important to making sure your vehicle is running as smoothly as possible, so it's crucial to make sure the lights themselves are working properly.
The check engine light is related to emissions systems. At Auto Masters, a quick check of the check engine light will help make sure you're not getting poor fuel economy and emitting higher levels of pollutants.
