Every car has an inbuilt computer that uses notifications to alert you of a problem in any part of the vehicle. Therefore, none of the warnings are optional. The check engine light is one of these notifications and is usually located just below the steering wheel. The problems are stored in a trouble code that can be decoded by an electronic scan tool.
Can I Drive with the Light On?
The action to take when the 'Check Light' illuminates depends on the behavior of the light. If the light flashes for more than six seconds, the problem could be a major one, and you should stop to check the car. In most cases, you will notice a problem with the vehicle. However, if the light does not flash, you can keep driving if the vehicle is not having operational issues. Make sure that a mechanic has diagnosed the problem and fixed it as soon as possible.
What are the Reasons for the Check Engine Light Illumination?
The check engine light could illuminate for several reasons. Here are some of the most common ones:
• A faulty oxygen sensor: The oxygen sensor checks the amount of oxygen in the exhaust system and relays it to the onboard computer to adjust the fuel and air mixture.
• A faulty gas cap: If the gas cap is loose, the light will come on due to the vapor leaks from the fuel tank. Consider checking the cap as the first thing when the light comes on.
• A failed catalytic converter: The catalytic converter controls the car's exhaust emissions by converting harmful gases into less toxic byproducts. If it fails, your vehicle may consume lots of fuel and perform poorly.
• Mass Airflow Sensor Failure: The MAF sensor determines the amount of fuel to be burnt in the combustion system based on the air available. If it is faulty, the car experiences a rough idle and decreased fuel economy.
• Faulty Spark plugs: Always replace your plugs according to the car's maintenance schedule. If they or the ignition coil fails, you may see the engine light and issues when starting your car.
