Find Out What's Going On With Your Check Engine Light

Background Of The Check Engine Light

The check engine light, as most of us know, is the standardized version that was introduced in 1996. The government-mandated that each vehicle sold in the United States be built with the same on-board diagnostics system (OBD-II) to help reduce vehicle emissions. Prior to this effort, various automakers had started implementing their versions of diagnostic systems in the early 1980s. However, there was no systematic use of fault codes, resulting in increased time and effort to diagnose engine troubles. With the OBD-II, a universal set of diagnostic trouble codes (DTC) is used. This makes troubleshooting vehicle issues more concise and timelier with check engine light diagnostics, regardless of the make and model. In addition to the engine, the OBD-II system also monitors the transmission and emissions system for signs of trouble. As a result, any change in behavior, no matter how small, will be detected and brought to your attention, allowing you to stay ahead of any problem. At Peterson Automotive Repair in Denton, Texas, we have years of experience inspecting, diagnosing, and fixing issues with our check engine light diagnostics services.

Reasons For A Check Engine Light To Come On

There are many reasons why your car’s check engine light might come on, and many of them are quick or easy fixes. However, it’s best not to leave anything to chance – especially since our service professionals can quickly and inexpensively troubleshoot the issue and provide a solution with our check engine light diagnostics! Did you know that a loose gas cap can be all it takes for the check engine light to come on? The leaking vapors from the fuel tank will trigger a nearby sensor and, subsequently, the check engine light. This also applies if the cap becomes cracked in any way. An issue with the emissions equipment can also render the light to illuminate. Key components of this group include the exhaust gas recirculation system, catalytic converter, and evaporative emissions detector. When compromised, additional items triggering the engine light include the oxygen sensor, mass airflow sensor, and spark plugs/spark plug wiring. If one fails, the OBD-II system will send the respective DTC to the car’s computer, triggering the check engine light.
