Four reasons why the engine light may come on
Model: (Various brands) Various
Video tutorial
For what reason can the engine warning light come on? The first reason is a malfunction of the camshaft sensors; if one of these sensors is not working properly, then the engine goes into emergency mode, so the engine will vibrate, there will be a reduction in power, and it will consume more fuel than usual; the second reason is a malfunction of the fuel injection system. If the injectors do not work properly, the fuel in the combustion chamber will not be burned correctly, so we will have to check the combustion. Another problem could be the spark plugs or coils, and we can have confirmation from an increase in consumption and poor engine ignition, while the last reason could be a faulty oxygen sensor: the faulty catalytic converter may have been damaged due to the oxygen sensor not working optimally.
