What are common reasons that a check engine light will turn on?When the check engine light comes on, it can create a fear that you could be on the cusp of an automotive disaster. However, it's possible that the light will illuminate because of something as inconsequential as a loose gas cap. Still, it's best to play it safe and visit the mechanic as soon as you can to have diagnostics performed. Here's a look at six common triggers of a check engine light.

Failing Mass Air Flow Sensor

This is what keeps tabs on incoming air and then makes a calculation on how much fuel to inject with it. In the event that this is the source of your check engine light turning on, it won't be wildly expensive to get it taken care of.

Faulty Catalytic Converter

This, on the other hand, is a problem that can cost a bundle. Nonetheless, it's a repair that you'll need because of the catalytic converter's important job, which is to transform carbon monoxide into an emission that doesn't have as detrimental of an impact on the environment.

Failing Oxygen Sensor

This monitors how much unburned oxygen there is in your exhaust system. Issues that arise with your oxygen sensor can lead to decreased gas mileage, as well as trouble with your catalytic converter.

Faulty Ignition Coil

The ignition coil plays a crucial role in generating the spark required for your engine to fire up and come roaring to life on all cylinders. Sometimes ignition coils will fail because of extreme weather temperatures, but can also go awry from just regular wear and tear.

Bad Battery or Charging System

A failing battery can cause low voltage, which can in turn trigger the check engine light.

Poorly-Fitting Gas Cap

An ill-fitting gas cap can result in the evaporation of fuel before it gets used, which could actually cause the check engine light to illuminate.
