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.
