Check Engine Light Diagnostics in College Station, Texas

Efficient and Accurate Diagnostics Troubleshooting


Behind the Check Engine Light

Vehicles are complex machines with many moving parts. The on-board diagnostic system was implemented in all models from 1996 and on to keep a better tab on how your vehicle is operating. The OBD-II system is integrated into your vehicle, and it constantly monitors the functions of your engine, transmission, and exhaust system. If it identifies an issue with one of these components, it alerts you via the check engine light in your dashboard. This warning light will be stagnant more often than not, and we encourage you to schedule an appointment at your earliest convenience. However, if you’re experiencing a flashing check engine light, a more serious problem has been detected, and we recommend pulling over and calling us for further instruction. Meanwhile, the associated diagnostic trouble code (DTC) is sent to your car’s computer system. Once you visit for check engine light diagnostics, we use our advanced equipment to read the code and determine the issue at hand. At Pro-Tec Auto Repair in College Station, Texas, we are well-versed in diagnosing and treating vehicle issues of all degrees.

Reasons for Your Check Engine Light to Come on

So, why did the check engine light come on in the first place? There are several reasons why the engine light can illuminate your dashboard. A faulty catalytic converter is one of the most common parts to trigger the engine light, also known as the malfunction indicator lamp (MIL). This component is responsible for converting harmful gasses (carbon monoxide, nitrogen dioxide, and hydrocarbons) into less harmful carbon dioxide and water vapor. A bad mass airflow sensor, failed oxygen sensor, and a vacuum leak are additional issues that can cause your MIL to appear, verified only through check engine light diagnostics. A complication with the exhaust gas circulation valves, air injection pumps, or positive crankcase ventilation can also occur. Pay attention to how your vehicle operates, too. Do you notice a rough idle? Is it hard to get your car running? Have you experienced a reduction in power output or fuel efficiency? Either exhibiting one of these symptoms alone or alongside the check engine light, we encourage you to visit for professional check engine light diagnostics soon.
