6 Common Causes of a Check Engine Light Coming On

Blog Banner

Often times, people assume that when their check engine light illuminates, 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 turn on. Regardless, it's important that you visit an auto shop that features reliable diagnostics to figure out quickly what is causing it to turn on, and then get the problem taken care of. Here's a look at six reasons a check engine light will turn on.

Failing Ignition Coil

The ignition coil plays an important role in creating the spark that is required for your engine to fire up on all cylinders. Sometimes ignition coils will fail because of extreme temperatures, but they can also falter as a result of regular wear and tear. Whatever the cause, if it goes awry it can cause your check engine light to come on.

Bad Oxygen Sensor

This is what monitors how much unburned oxygen is in your exhaust system. Problems with your oxygen sensor can lead to a reduction in fuel-efficiency, as well as issues with your catalytic convertor.

Faulty Mass Air Flow Sensor

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

Failing Catalytic Convertor

This keeps tabs on carbon monoxide and converts it into a less harmful emission. This, on the other hand, is a fairly expensive repair. Nevertheless, it's an important component of your vehicle, and will need to be taken care of quickly.

Bad Battery or Charging System

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

Faulty Gas Cap

An ill-fitting gas cap can actually result in fuel evaporating before it is even used, which can consequently cause a check engine light to illuminate.
