The check engine light in our cars can make drivers uneasy, especially when you don’t know why it has turned on. Here are the most common reasons why that pesky little indicator has lit up to ruin your day.
Oxygen (O2) Sensor
This part measures the amount of unburned oxygen in your car’s exhaust system. If not replaced it can lead to your engine burning more fuel than necessary, even causing damage to your spark plugs and catalytic converter.
Loose Gas Cap
Other than serving as a cover for your gas tank after you fill up, the gas cap also keeps gasoline fumes from entering the atmosphere while your car is off. Not replacing it can cause your gas to evaporate, meaning you will lose fuel faster and have to make more trips to the pump.
This part helps protect the environment by converting harmful carbon monoxide to carbon dioxide. If you don’t repair or replace it when there is a problem, your car won’t pass an emissions test. A faulty converter can also make your car run at a high temperature as well, meaning that you could burn oil more rapidly and put more stress on engine components.
Mass Airflow Sensor (MAF)
This part’s main responsibility is to measures the amount of air entering the engine to determine how much fuel is needed to run your engine efficiently. It’s important to get this part fixed right away if your sensor goes off as it could lead to your spark plugs, oxygen sensor and catalytic converter.
Spark Plugs or Plug Wires
Spark plugs ignite the air and fuel mixture in the combustion chamber to get your car started. The plug wires deliver the spark from the ignition coil the spark plugs. Much like other parts, this will lead to reduced performance for your vehicle and cause your catalytic converter to clog.
