The check engine light, sockitforward.com 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 emissions system. The light can come on for a variety of reasons, some of which are minor and others that are more serious.
Here are some of the most common reasons why your check engine light might be on:
- 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 not tightened properly, it can cause the check engine light to come on.
- Worn spark plugs or spark plug wires. Spark plugs ignite the fuel-air mixture in the engine, and if they’re worn out or damaged, they can cause the check engine light to come on.
- Faulty oxygen sensor. The oxygen sensor measures the amount of oxygen in the exhaust gas, and if it’s not working properly, it can cause the check engine light to come on.
- Clogged catalytic converter. The catalytic converter helps to reduce emissions from the engine, and if it’s clogged, it can cause the check engine light to come on.
- Misfiring engine. If one or more of the cylinders in your engine are misfiring, it can cause the check engine light to come 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.
