What Is Engine Management Light?

The Engine Management Light (EML), often known as the Check Engine Light, is a vital dashboard warning light that detects a problem with your vehicle's engine, exhaust, or emissions system. When the EML lights up, it indicates that your car's sensors have identified a problem that requires your attention. These sensors keep track of numerous components and systems to ensure that everything runs smoothly. If they detect something odd, such as an engine malfunction or an emissions system problem, then the sensor will notify the engine control unit (ECU) which then turns on the EML.

As mentioned above, it's important not to ignore this warning light. While the underlying issue might be as simple as a loose fuel cap, it could also indicate a more significant problem, like a damaged catalytic converter. Addressing this will help you prevent further damage to your vehicle and save you money on additional costly repairs.

Driving through a red light can do considerable damage to your car, resulting in costly repairs and jeopardizing your safety.
