6 Reasons a Check Engine Light Will Illuminate


6 Reasons a Check Engine Light Will IlluminateIf your check engine light turns on, it doesn't necessarily mean that you're on the verge of an automotive catastrophe. Still, it'll be best to soon get to the shop for diagnostics so that you don't end up spending a ton of money on repairs that could've been prevented. Here's a look at six common check engine triggers.

Faulty Oxygen Sensor

This monitors the quantity of unburned oxygen in your exhaust system. Indications of oxygen sensor trouble include decreasing gas mileage, as well as issues arising with your catalytic converter.

Failing Mass Air Flow Sensor

Your mass air flow sensor keeps track of incoming air and determines the amount of fuel that should be injected with it. If this is what's causing your check engine light to come on, you'll be lucky in that it shouldn't cost too much to remedy.

Bad Catalytic Converter

A failing catalytic converter, however, can be a rather costly issue to address. Nevertheless, it'll need to be done because of the important work that it does, which is to turn carbon monoxide tinto an emission that doesn't hurt the environment as badly.

Faulty Ignition Coil

Ignition coils serve an important role in creating the spark necessary for your engine to fire up on all cylinders. In some cases, ignition coils will go bad as a result of extreme weather conditions.

Bad Battery/Charging System

If your battery is failing, it can lead to low voltage at the computer, which can then cause your check engine light to illuminate.

Poorly-Fitting Gas Cap

A loose or missing gas cap can cause fuel to evaporate before you get the opportunity to use it. As bizarre as it might seem, this issue can actually trigger a check engine light.
