Why is my check engine light on? Here are six common reasons


Why is my check engine light on? Here are six common reasonsJust because your vehicle's check engine light has turned on, doesn't necessarily mean that you are on the brink of automotive disaster. However, it is still very important that you get to the mechanic for diagnostics so that you can take care of the problem, whatever it might be. By being proactive about this, you may very well end up saving yourself from unnecessarily extensive---and expensive---repairs. Here's a look at six common causes of a check engine light coming on.

Failing Ignition Coil

Your ignition coil helps to generate the spark that your engine requires to come roaring to life. One cause of ignition coil failure is extreme weather.

Bad Spark Plugs/Wires

If you procrastinate on changing out bad plugs and wires, you could end up having problems with your ignition coil and catalytic convertor.

Faulty Oxygen Sensor

This is what keeps monitors the quantity of unburned oxygen in your exhaust system. Problems with your oxygen sensor can cause a decrease in gas mileage, as well as issues with your catalytic convertor.

Bad Mass Airflow Sensor

This keeps tabs on how much air is coming in and then determines how much fuel it should be injected with. Luckily, this repair is rather affordable.

Failing Catalytic Convertor

This is a more expensive fix, but it's a necessary one. The catalytic convertor tracks carbon monoxide and then is able to transform it into an emission that isn't as harmful to the environment.

Loose Gas Cap

If your gas cap isn't providing a proper seal, fuel can evaporate before you get the chance to use it, which can actually trigger the check engine light.
