What Can Cause Your Check Engine Light to Come on in Your Vehicle
There are several things that can cause that check engine light to come on in your vehicle. Here are some issues that can cause that chime to sound and the light to come on that you might not be suspect:
– Faulty Gas Cap: If you have a gas cap that has become loose or is faulty for some reason, the vapors that escape can cause the check engine light to come on. There are valves that are located inside the fuel tank that keep the vapors circulating rather than escaping. This is a problem that is usually fixed rather easily and won’t require most drivers to get help from a professional mechanic.
– Faulty Catalytic Converter: Many drivers don’t even fully understand what their catalytic converter does. This important part of your car works to convert carbon monoxide into carbon dioxide. This part of your vehicle is one that is often stolen for those looking for the precious metals found inside of it. It plays a large role in your vehicle’s emissions, and if you have a faulty catalytic converter, your vehicle will not be able to run properly. If this is what is causing your check engine light to come on, you will definitely need the help of a professional to fix it.
– Spark Plug Replacement: Spark plugs are another essential part to your vehicle. When they start to get worn, it can cause your check engine light to come on. They work to create a mixture of fuel and oxygen to create combustion and get the engine started. If you are having a difficult time getting your vehicle started and have a check engine light that is on, you might need a spark plug replacement.
– Oxygen O2 Sensor Failure: You might not realize how important your vehicle’s oxygen O2 sensor is, but this important part of your car works to measure the amount of oxygen that is left unburnt in your vehicle’s exhaust system. A faulty O2 sensor will definitely trigger your check engine light to come on.
