Check Engine Light: A Guide to What It Means and How to Fix It

The check engine light, maruti-consultancy.com also known as 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 keep the fuel vapors from escaping the fuel tank, and if it’s loose or faulty, it can cause the check engine light to turn on.
• A misfiring engine. This means that one or more of the cylinders in your engine is not firing properly. This can be caused a number of things, such as a bad spark plug, a faulty ignition coil, or a problem with the fuel system.
• A faulty oxygen sensor. The oxygen sensor measures the amount of oxygen in the exhaust gas, and it 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 clogged catalytic converter. The catalytic converter helps to reduce harmful emissions from your car’s exhaust. If the catalytic converter is clogged, it can cause the check engine light to come on.
• A problem with the fuel system. This could include a problem with the fuel pump, the fuel injectors, or the fuel filter.

If your check engine light comes on, it’s important to have it checked out a mechanic as soon as possible. The sooner the problem is diagnosed and fixed, the less likely it is to cause further damage to your car’s engine.
