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 can come 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.

- Catalytic converter problems. The catalytic converter is a device that helps to reduce emissions from your car. If the catalytic converter is damaged or clogged, it can cause the check engine light to come on.
- Oxygen sensor problems. The oxygen sensor is a sensor that measures the amount of oxygen in the exhaust gas. If the oxygen sensor is faulty, it can cause the check engine light to come on.
- Other problems. The check engine light can also come on for a variety of other reasons, such as a problem with the fuel pump, the fuel injectors, or the engine control module.
