When the check engine light illuminates, the cause could be something as simple as a loose gas cap---if you're lucky. Nonetheless, it could be something serious and you'll want to play it safe and get to the mechanic for diagnostics. Here's a look at six common causes of a check engine light turning on.

Failing Ignition Coil

The ignition coil plays a primary role in generating the spark that is necessary to get your engine to fire up. Sometimes an ignition coil will fail because of weather extremes, but standard wear and tear will also eventually lead to failure.

Faulty Mass Airflow Sensor

This is the component that keeps track of the amount of air coming in and then calculates just how much fuel to inject with it. The good news, however, is that if this is your issue, it's an affordable repair.

Failing Catalytic Convertor

This, on the other hand, is a more expensive fix. Nonetheless, it's a necessary one because it's needed to convert carbon monoxide into a less harmful emission.

Bad Spark Plugs

Old spark plugs can lead to clogging of the catalytic convertor, as well as damage to your ignition coil.

Failing Battery or Charging System

Depending on what year your car was manufactured, it's entirely possible that this is why the light is illuminating.

Loose Gas Cap

This might seem strange, but it's true. If your gas cap isn't properly sealed, then gasoline can evaporate before you actually get the chance to use it, which can actually trigger your check engine light.
