Article by Delta Driving School

The warning lights that come on in your car have been designed to help drivers maintain full control of their vehicle when they are driving. When you drive a car there is a lot of things going on under the hood to give you a smooth and safe driving experience. From making sure the wheels can steer properly to making sure each part of the car is getting enough power to function well, your car has to monitor a number of different functions and levels.

There are many different components that make up your car’s engine. There are some common reasons why your “check engine” light might suddenly come on. Knowing these common issues can help you diagnose the problem in a timely and effective manner.

Gas Cap

One reason why your check engine light may come on may be because something is wrong with the gas cap. This cap seals the tank where the fuel your car runs off of is stored. This prevents fuel and hazardous fumes from accidentally spilling out of the tank, which can be harmful to your health and the atmosphere. Make sure the tank cap is not damaged, loose, or gone.

Oxygen Sensor

Another common reason why your check engine light may be on is because your oxygen sensor needs to be replaced. This sensor is responsible for monitoring how much unburned oxygen there is within your car. If your sensor is not working properly you may end up burning fuel inefficiently, leading to a larger fuel consumption than necessary.
