Check Engine Light: Notes
All vehicles are equipped with a CHECK ENGINE light, located on the instrument panel. The light will illuminate when the ignition switch is turned to the ON position (bulb check) and engine is not running. Light should not flash at this time and should go out when engine is started.
When the CHECK ENGINE engine light remains on or flashes, with the engine running, the self-diagnostic system has detected a problem. If the problem goes away, the light will go out after 10 seconds, but a trouble code will remain stored in the ECM memory.
