What issues trigger the check engine light?The illumination of the check engine light doesn't automatically mean that your vehicle is on the verge of disaster. Nevertheless, it's important to get to the shop for diagnostics so that you can nip any issues in the bud before they worsen and necessitate expensive repairs. Here's a look at six common reasons that a check engine light turns on.

Bad Battery/Charging System

When a battery is failing, it can cause low voltage at the computer, which can consequently cause the check engine light to come on.

Failing Mass Air Flow Sensor

Air flow sensors keep tabs on incoming air and then determine home much fuel should be injected with it. Fortunately, if this is your problem, it shouldn't be too expensive to remedy.

Faulty Catalytic Converter

On the other hand, if your catalytic converter fails, it could be rather expensive to address. Still, you'll need to make sure you're driving with a properly functioning catalytic converter because of its important job, which is to turn carbon monoxide into an emission that isn't as damaging to the environment.

Failing Oxygen Sensor

Oxygen sensors monitor how much unburned oxygen is in the exhaust system. Trouble with an oxygen sensor can lead to a drop in gas mileage, as well as problems with the catalytic converter.

Faulty Ignition Coil

Ignition coils are pivotal in generating the spark that's necessary for your engine to fire up on all cylinders. Sometimes, ignitions coils will fail because of extreme weather conditions.

Loose/Missing Gas Cap

While this might seem like a trivial issue, it can trigger a check engine light. A loose or missing gas cap can result in gas evaporating before you get the chance to use it.
