What are common check engine light triggers?

While this isn't necessarily the case, you'll still want to get to the shop for diagnostics so that you don't risk needing expensive repairs that could've been prevented. Here's a look at six common reasons that a check engine light turns on.

Failing Ignition Coil

Bad Battery or Charging System

When a battery goes bad, it can cause low voltage at the computer, which can consequently trigger your check engine light.

Failing Mass Air Flow Sensor

This keeps tabs on the amount of incoming air and calculates how much fuel to inject with it. If this is what is causing your light to illuminate, it shouldn't cost an exorbitant amount to get it taken care of.

Bad Catalytic Converter

A failing catalytic converter, however could hit you hard in the pocketbook. Nonetheless it'll need to be done because of the catalytic converter's important job, which is to turn carbon monoxide into an emission that is less harmful to the environment.

Faulty Oxygen Sensor

Oxygen sensors monitor the quantity of unburned oxygen in the exhaust system. When they start to go haywire, you could see a drop in gas mileage, as well as issues with your catalytic converter.

Loose/Missing Gas Cap

If a gas cap is missing or poorly-fitting, then fuel can evaporate before you get the opportunity to use it. Although it might seem strange, this is an issue that can actually trigger you check engine light.
