Engine Light On? 10 Common Reasons and What to Do

The check engine light, also known as www.attacproject.eu/ the malfunction indicator light (MIL), is a warning light on your dashboard that indicates a problem with your car’s engine or emissions system. The light can come on for a variety of reasons, some of which are more serious than others.

Here are some of the most common reasons why your check engine light might be on:

• A loose or faulty gas cap. This is one of the most common reasons why the check engine light comes on. The gas cap helps to seal the fuel tank and prevent gasoline vapors from escaping. If the cap is loose or faulty, it can cause the check engine light to come on.
• A problem with the oxygen sensor. The oxygen sensor measures the amount of oxygen in the exhaust gas and helps the car’s computer to adjust the air-fuel mixture. If the oxygen sensor is faulty, it can cause the check engine light to come on.
• A misfire in the engine. A misfire occurs when one or more of the cylinders in the engine is not firing properly. This can be caused by a variety of problems, such as a bad spark plug, a faulty ignition coil, or a problem with the fuel system.
• A problem with the catalytic converter. The catalytic converter is a device that helps to reduce emissions from the car’s exhaust. If the catalytic converter is faulty, it can cause the check engine light to come on.
• A problem with the emissions system. The emissions system is responsible for ensuring that the car’s emissions meet federal standards. If there is a problem with the emissions system, it can cause the check engine light to come on.
