How Does the Check Engine Light Work?

All light-duty vehicles and trucks from 1996 and beyond are designed with the second-generation on-board diagnostics system (OBD-II), a computer-based system that continuously monitors the major components of a vehicle. If its network of sensors detects a problem, a signal will be sent to and stored in the OBD-II system; the check engine light will then illuminate to alert the driver. The system is designed with different trouble codes to regulate its operation. Once a technician accesses the system's information and trouble code with a scan tool or code reader, they can determine the problem area of the vehicle. These tools will not provide an exact reason for engine light; it simply points them to the part that is exhibiting a complication. From there, they conduct a thorough inspection to troubleshoot the issue.

What Can Trigger the Engine Light?

The reasons why the engine light comes on can be minor or major. The most minor is a loose gas cap on your vehicle. If you secure the gas cap and the check engine light is still present, we recommend a visit to your local auto repair shop for proper diagnosis. So, what triggered your engine light? The OBD-II system monitors the engine computer, which means a multitude of components can be at fault. The most common include worn or damaged spark plugs, worn spark plug wires, loose or cracked hoses and manifolds, faulty oxygen sensors or mass airflow sensors, a bad catalytic converter, or low oil pressure. There could also be a problem with your exhaust system, which is responsible for processing your engine's harmful byproducts. Determining the precise issue correctly takes meticulous craftsmanship, patience, and dedication—the kind of commitment that you will find here in our repair facility.
