Check engine light, what you need to know
The problem could be as simple as failing to replace your gas cap properly after a fill up or as complex as engine or transmission malfunction, so it is in your best interest to let the experts determine the source of the problem whenever your check engine light comes on. A certified repair technician has the knowledge and the access to equipment essential to a proper diagnosis of your problem. Examples of issues that demand a quick and proper diagnosis include sudden illumination of dashboard warning lights (such as the check engine light), emission failure, engine or transmission performance or steering and ride control malfunction. The diagnostic process will include a scan test to retrieve stored trouble codes and a check of systems and components to eliminate possible causes. In many cases, diagnosis and correction of the problem can take place within the same day.
