Understanding the Check Engine Light

Did you know a car’s check engine light is part of its onboard diagnostics system? Since 1996, every vehicle manufactured for the United States has been standard equipped with OBD-II, the second-generation onboard diagnostics software. It constantly monitors the engine, transmission, and exhaust system to ensure the proper operation of each system. If a problem is detected, it registers through a “diagnostic trouble code” stored in the computer. This triggers the check engine light, sometimes known as the malfunction indicator lamp. It will illuminate in the dashboard, yielding that your vehicle requires the attention of professional assistance and check engine light diagnostics.

Why Is Your Check Engine Light On?

So, what are a few common reasons why your check engine light may be on? Generally, any issue with the air and fuel delivery systems or processes, ignition system, or sensors and modules can trigger the engine light. More specifically, it can be traced back to a myriad of components. If the spark plugs are worn or the spark plug wires frayed, combustion is compromised, yielding subpar performance. Because of this, the engine light will come on. Additional examples that we’ll be able to determine via check engine light diagnostics include a faulty catalytic converter, mass airflow sensor, evaporative emissions purge control valve, ignition coil, or fuel injector. It’s important to note that something as simple as a loose gas cap can be the culprit. If you have recently fueled up, quickly check that the gas cap is securely on; a broken or cracked gas cap will have the same outcome.
