What is causing my check engine light to come on?

Many people assume that when their check engine light comes on, disaster is just around the corner. While it certainly can mean that you have a significant problem on your hands, there are also some less serious issues that can cause the check engine light to illuminate. Regardless, it's important that you figure out quickly what is causing it to turn on, and then get the problem taken care of.

Nowadays, modern auto shops have state-of-the-art diagnostic equipment that uses high-tech computerization to quickly figure out what exactly is wrong with your vehicle that is causing the light to come on. There are a number of reasons that your check engine light might illuminate. Here's a look at five possibilities.

Faulty Ignition Coil

This plays an important role in generating the spark that is needed for your engine to fire up on all cylinders. Sometimes ignition coils will falter because of extreme temperatures, but they can also fail as a result of standard wear and tear. Regardless of the cause, if it goes bad it can cause your check engine light to come on.

Bad Battery or Charging System

Depending on the kind of vehicle that you drive, this could also be the cause of the light illuminating.

Faulty Mass Air Flow Sensor

This what monitors incoming air and then figures out how much fuel to inject with it. If this is what is causing the check engine light to come on, you won't be put out too badly, since this is a relatively cheap fix.

Failing Catalytic Convertor

This keeps track of carbon monoxide and converts into a less harmful emission. This, however, is a fairly expensive repair. Nonetheless, it's an important component of your vehicle, and will need to be addressed quickly.

Faulty Gas Cap

If this is your problem, you're in luck. An ill-fitting gas cap can result in fuel evaporating before it is even used, which can actually cause a check engine light to illuminate.
