What Does the Check Engine Light Mean?

The Check Engine light, also known as the Malfunction Indicator Lamp (MIL), is triggered when your car’s ECU (Engine Control Unit) detects an abnormal reading from one or more systems. These systems may include the engine, fuel delivery, ignition, emissions, exhaust, sensors, or transmission.

In some cases, the issue may be minor, such as a loose sensor or incorrect air-fuel mixture. In other cases, it may indicate a serious problem that can damage the engine, catalytic converter, or transmission if ignored. The only accurate way to understand the cause is through a proper computerized ECU diagnostic scan.
