Reason Why Check Engine Light Comes On

The primary reason the check engine light comes on is because of the emissions problem. Specifically, there are lots of issues to discuss. In this part of our essay, you can learn more about why the check engine light comes on.

  • Bad Catalytic Converter

The catalytic converter controls the emission system of your car. It converts carbon monoxide and toxic gases that come out of your vehicle into less dangerous byproducts. And if something wrong happens with the converter, then the check engine light comes on.

  • Bad Fuel Or Gas Cap

A bad or cracked gas cap is another reason why the check engine light comes on. And a lousy fuel cap allows the fuel vapor to exit from the tank. As a result, the check engine light comes on.

If you replace the wrong cap or tighten them, it will solve the problem. But you have to figure it out with a professional hand.

  • Bad Spark Plugs

We know the spark plugs are crucial components of a car engine. And if the spark plugs don't work well, the check engine light automatically comes on.

If you don't check them for months, they will start to interrupt. And if it starts to bother you too much, replace them immediately.

  • Bad Mass Airflow Sensor

A faulty Bad Mass Airflow Sensor can also turn the check engine light on. If it gets dirty or doesn't install correctly, it triggers the check engine light on. It's not an emergency case, though, but if you find out, it's the issue with the Mass Airflow Sensor, repair it with a professional. Remember, it's a highly technical issue.

  • Bad Ignition Coil

A burning ignition coil or the shortening of it causes the check engine light on. Mainly, the ignition coil converts the voltage of the car to the required volts.

And it induces the spark plug to produce sparks that burn the fuel inside the cylinder. The whole process can not work if the ignition coil gets void.

If the check engine light keeps lighting on and you can't find any clue of its reason, then ask the mechanic to check into the ignition coil. It will help if you take a cautious look at that.

Conclusion

Driving with the check engine light is safe until it becomes a terrifying issue. So, firstly you must observe the behavior of your car whether it's acting something odd.

If you feel everything is fine as before, except the check engine light is on, then you can drive further. But the trick of the separate trips is a must-do.
