What the Check Engine Light Could Mean


When you are driving, it is important to pay attention to the lights on the dashboard. This is the area that will illuminate if there is an issue with the vehicle, or under the hood. If the engine warning light comes on while you are driving, pull over at the earliest and safest chance to have a look under the hood. Since the engine warning light can illuminate for any possible reason, it does not tell you exactly what to look for. Seeing the words ‘Check Engine’ is not actually that helpful. It could be that there is a malfunction in your management system and this will need to be addressed as soon as you can bring it in. If the light flashes and does not totally light up, the first action you should take is to reduce your speed. If the light then goes out, it is just a glitch. If the light then comes on and stays on as a solid light, you can safely continue the journey, but keep your speed lower.


Oxygen Sensor

Sometimes the engine light will come on if your oxygen sensor fails or malfunctions. Any sensor that is not able to function correctly will trip the management system to switch on the engine light. Having problems with a sensor does not mean you have to stop your vehicle immediately. If you are not sure what the issue is, make sure to bring the vehicle in so we can inspect it for you.


Emission Control System

The malfunction indicator lamp, or engine warning light may also illuminate to warn you that there is a problem with your emission control system. This can stretch to an exhaust issue, a catalytic converter issue, or an engine issue.


Electrical Problems

Your engine light will notify you that there is an issue with the engine. In order to determine it, your vehicle will have to be diagnosed to find out the cause. If you are having some obvious trouble with the electrical parts, like lights not working or fuses blowing or relay switches malfunctioning, then the engine light may come on.


Light Malfunction

In some rare cases the engine light will come on, not because there is an issue with the engine, but a malfunction with the light itself. If this happens, you can try resetting the check engine light. If there is a problem with the engine you can guarantee that the engine warning light will come back on again at some point soon. Anytime you notice anything out of the norm with your vehicle, make sure to bring the vehicle in so we can inspect it for you.
