The Checks Engine Lights: What It Means and What to Do

The check engine light www.competitiveinsurancequote.net , also known as the malfunction indicator light (MIL), is a warning light on your car’s dashboard that indicates a problem with the engine or emission control system. The light may be on for a variety of reasons, some of which are more serious than others.

Common reasons for the check engine light to come on:

• Loose or faulty gas cap: This is one of the most common reasons for the check engine light to come on. When the gas cap is loose, it allows gasoline vapors to escape, which can trigger the light.
• Misfiring engine: A misfiring engine is when one or more of the cylinders in your engine is not firing properly. This can cause a variety of problems, including decreased fuel economy, increased emissions, and engine damage.
• Faulty oxygen sensor: The oxygen sensor measures the amount of oxygen in your exhaust, and it helps your car’s computer adjust the air-fuel ratio. If the oxygen sensor is faulty, it can cause the check engine light to come on.
• Catalytic converter problems: The catalytic converter is a device that helps reduce emissions from your car. If the catalytic converter is damaged or clogged, it can cause the check engine light to come on.
• Other problems: There are a number of other problems that can cause the check engine light to come on, such as a bad spark plug, a faulty fuel injector, or a problem with the engine control module.

What to do if your check engine light comes on:

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 repaired, the less likely it is to cause further damage to your car.
