The check engine light is part of your car’s onboard diagnostics system.
Over the past few decades, computers increasingly have controlled and monitored vehicle performance . When it finds a problem in the that it can’t correct, the on-board computer turns on a yellow warning indicator labeled “check engine,” “service engine soon,” or “check powertrain.” In addition to turning on the light the computer stores a “trouble code” in its memory that identifies the source of the problem, such as a malfunctioning sensor or a misfiring engine. The code can be read with an electronic scan tool or a diagnostic computer. Let Phillips help diagnose the cause of your check engine light.
