6 Reasons a Check Engine Light Will Illuminate

6 Reasons a Check Engine Light Will IlluminateWhen a check engine light comes on, it can understandably cause a driver to worry. However, this light doesn't always mean that a major problem is looming. The important thing is to play it safe and promptly get to a shop that has technologically advanced diagnostic equipment that can get the problem identified and remedied as quickly as possible, so that you can get back on the road with little delay. Here is a look at six common reasons that a check engine light will turn on.

Bad Ignition Coil

This is instrumental in creating the spark that is required for your engine to fire up on all cylinders. Ignition coils can go haywire from extreme weather temperatures, but also just from standard wear and tear.

Failing Battery or Charging System

Depending on the specific year that your vehicle was made, this could be the cause of the light turning on.

Bad Mass Air Flow Sensor

This tracks incoming air and makes a determination on how much fuel to inject with it. If this is what is causing your check engine light to illuminate, there's no need for much worry because this is a rather affordable issue to address.

Failing Catalytic Converter

The purpose of a catalytic converter is to turn carbon monoxide into an emission that is gentler on the environment. Unlike the mass airflow sensor, if this is your issue, it could well cost a significant chunk of change.

Faulty Oxygen Sensor

This is what keeps tabs on the amount of unburned oxygen in your exhaust system. Trouble with your oxygen sensor can result in worsening gas mileage, as well as problems with your catalytic converter.

Poorly-Fitting Gas Cap

If your gas cap isn't on tightly, then fuel can actually evaporate before it gets used, which can consequently trigger the check engine light.
