What makes a check engine light come on? Here's a look at six reasonsWhile it should be concerning to see a check engine light turn on, it doesn't necessarily mean that you're on the verge of an automotive calamity. In such a situation, it can be useful to visit a reputable auto shop that uses technologically advanced diagnostic equipment so that you can get a fast and accurate determination of what is causing the issue. Here's a look at six common reasons that a check engine light will turn on.

Faulty Ignition Coil

This plays a crucial role in creating the spark that your vehicle needs to fire up on all cylinders. While ignition coils will fail from standard wear and tear, they can also go awry because of extreme weather temperatures.

Bad Mass Airflow Sensor

This keeps tabs on incoming air and determines how much fuel to inject with it. Fortunately, this is a rather affordable issue to address, so you're pretty lucky if this is what is causing the light to illuminate.

Failing Catalytic Converter

Your catalytic converter turns carbon monoxide into an emission that isn't as harmful to the atmosphere. This, however, is a more expensive fix. Nonetheless, it's an important one that you'll need to get done quickly.

Faulty Oxygen Sensor

This is what monitors the quantity of unburned oxygen in your exhaust system. Issues with your oxygen sensor can lead to worsened gas mileage, as well as problems with your catalytic converter.

Bad Battery or Charging System

Depending on how recently your car was manufactured, this could also be a cause of the light coming on.

Poorly-Fitting Gas Cap

If your gas cap doesn't fit correctly, fuel could evaporate before you get the chance to use it, which could possibly trigger the check engine light.
