In some cases the light may be showing more than just the logo of an engine and maybe with the word ‘check’.
The computer also stores a trouble code in its memory that shows the source of the problem such as a misfiring engine or a malfunctioning sensor in addition to turning on the light that is known as the international check engine symbol. Tools such as a diagnostic computer or an electric scan tool can be used to read the code. There are also other inexpensive code readers that are created for do-it-yourselfers.
