The Check Engine Light indicator can signal three different types of problems.
- Occasional flashes indicate temporary engine malfunctions. In this case, it is good to be aware of the possible forthcoming issues which can later on turn to more serious ones.
- The most common case is when the indicator light stays on constantly. It indicates more serious problem that requires action to be taken; the sooner the better. Although, sometimes the issues aren’t that serious but can affect the emissions of the vehicle, for example.
- The most serious type of signaling is when the MIL flashes constantly. It is a sign that your vehicle’s engine is seriously misfiring. The issue is major and the engine should be stopped immediately to prevent serious damage. For instance, the condition might cause the catalytic converter to overheat and even cause a fire.
