Common Reasons Why Your Check Engine Light Is On

One of the most frustrating things that can happen while you’re driving is to have your check engine light come on. Not only is it annoying, but it can be expensive to get fixed if there’s a serious problem. And worst of all, you may not even know what the problem is!

Fortunately, there are some common reasons why your check engine light might come on, and we’ve compiled a list of them here. So before you panic or call a tow truck, take a look at this list and see if any of these reasons apply to you.

1. Loose or Damaged Gas Cap

This is one of the most common and easiest problems to fix. If your gas cap is loose or damaged, it can cause your check engine light to come on. By recirculating gasoline vapors, the valves in the gas tank prohibit them from leaving. The CEL might be activated if the gas cap is unfastened. The gasoline system fails to circulate effectively due to a malfunctioning or missing gas cap. The solution is simply to replace the gas cap with a new one.

2. Faulty Oxygen Sensor

Another common problem is a faulty oxygen sensor. This sensor measures the amount of oxygen in the exhaust and sends that information to the computer. If it’s not working properly, it can cause the check engine light to come on. The fix is to replace the oxygen sensor.

3. Catalytic Converter Issues

The catalytic converter helps to reduce emissions by converting them into less harmful gases. If it’s not working properly, it can cause the check engine light to come on. Simply replacing the converter may not address the problem since the failure is caused by something else, such as a burst head gasket. To overcome this problem, you will require expert assistance.

4. Worn Spark Plugs

If your spark plugs or wires are worn, they can cause the check engine light to come on.

The spark plugs aid to ignite a combination of gasoline and oxygen to cause combustion and power the engine’s cylinders. When the spark plugs do not ignite properly, an engine misfire might occur.
