Professional Diagnostics Testing and Repair
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. At Trinity Auto Haus in Waco, Texas, we have many years of experience performing diagnostics services and fixing associated problems. The check engine light is an issue that can cause any car owner to worry, but we do everything we can to remedy the issue efficiently and get you back on the Road!

Reasons for the Check Engine Light to Come on
There are a range of reasons why your check engine light can come on, and luckily, most of them are quick fixes. With that being said, it’s best not to leave anything to chance, especially since our auto repair shop can quickly and inexpensively determine the issue with check engine light diagnostics and provide a solution. A complication with the emissions equipment is notorious for triggering the check engine light. Components of this group include the exhaust gas recirculation system, the catalytic converter (an important part that converts harmful gasses into less-harmful gasses), and the evaporative emissions detector. These high-tech devices work together to minimize your vehicle’s tailpipe emissions. A bad oxygen sensor, which regulates the engine’s air/fuel ratio, vacuum leak, damaged spark plugs, and faulty mass airflow sensor, are additional issues that can be the source of the check engine light’s illumination. If you experience a flashing CEL, we recommend pulling over and giving us a call for further instruction; this often indicates a serious issue is occurring, and it may be unsafe to drive. The only way to know what is going on is to bring your vehicle in for check engine light diagnostics.
