Get to know All About the Check Engine Light

Know about the valid reasons why you need the check engine light? If it is your Check Engine Light (Which should be yellow or orange, and usually looks like an engine), what this is telling you is your Engine Control Module (ECM) has an issue with a component that it can’t fully rectify. In case the light appears, the ECU stores what is also known as the diagnostic trouble code (DTC).

Not all people are so intimidated by the check engine light and in fact, some motorists don't even realize what it's there for. The on-board diagnostic computer that is standard in newer vehicles is constantly monitoring numerous systems, and all the parts associated with those systems. When the computer detects a problem, it sends out a signal to illuminate the warning light so you know it's time to get your vehicle into the shop for a professional diagnosis.
