Depending on the manufacturer, check engine lights are either orange, yellow, or amber in color.If the light begins to flash, on the other hand, it signifies a more significant problem, such as a misfire, which may cause the catalytic converter to overheat very rapidly.These emissions devices run at high temperatures in order to reduce emissions, but if they malfunction, they can cause a fire.
The check engine light is a warning indicating the onboard diagnostics system (also known as OBD II) has discovered a problem with the vehicle’s emissions, ignition, fuel, or exhaust systems, and has initiated a diagnostic procedure.
A check engine light, in its most basic definition, is a device that shows that the Onboard Diagnostics (OBD) of a car’s computer has discovered a problem with the vehicle. The Engine Control Unit, often known as the ECU, is the unit that continuously checks the components of the vehicle in order to identify any abnormalities.
