How the Check Engine Light Works
As a vehicle owner, it’s important you understand the basic functions of your car, truck, SUV, or van. If yours is a 1996 model or newer, your vehicle comes with the second-generation onboard diagnostics system (OBD-II). This diagnostics system is constantly monitoring various systems and components in your car, with some of the most pertinent being your engine, transmission, and emissions system. If it detects a change from the normal operation of one of these components, it triggers the check engine light (CEL) to illuminate your dashboard. A problem that gets detected by the OBD-II system is automatically assigned a diagnostic trouble code (DTC), also known as a fault code. This code is stored in your car’s computer system, which will then be retrieved and identified through the check engine light diagnostics.
