5 Reasons Why a Check Engine Light Turns On

It seems as though we've all seen it turn on at some point, and when it does, the impulse is to worry that your engine is on the verge of catastrophe. However, just because your check engine light has illuminated doesn't necessarily mean that disaster is nearing. In fact, there are several relatively minor issues that can cause the light to come on. Nonetheless, you'll want to figure out as quickly as possible why it is happening.

Fortunately, modernized auto shops have highly-sophisticated diagnostic equipment that can help them get to the root of the problem in a timely fashion. There are a number of issues that can cause a check engine light to turn on. Here is a look at five possibilities.

Bad Mass Air Flow Sensor

This keeps track of 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, you're not in too bad of shape. This is a relatively inexpensive fix.

Faulty Catalytic Convertor

This is what alters carbon monoxide, turning it into an emission that is less harmful to the environment. Unfortunately, if this is your issue, it could well take a significant chunk of change to get it taken care of. Nonetheless, it's an important part of your car and needs to be addressed promptly.

Failing Ignition Coil

This plays a major role in creating the spark that is necessary for your engine to fire up on all cylinders. Ignition coils can go bad from extreme weather temperatures, or also just from standard wear and tear. Whatever the reason, if it is failing, it can be the cause of your check engine light coming on.

Bad Battery or Charging System

Depending on the year that your car was manufactured, this could be the cause of the light illuminating.

Faulty Gas Cap

Wouldn't it be great if this was the problem? If your gas cap fits poorly, gas can evaporate before it gets used, which can actually cause the check engine light to turn on.
