3 Reasons Why Your Check Engine Light Might Be On

Everyone has experienced this at some point: You get into your (seemingly well-functioning) car and put your key in the ignition. As you turn your car on, you see that your “check engine” light is on. You might panic, or you might be annoyed because your car seems to be working perfectly fine. But what exactly causes your check engine light to appear? Is it really your engine that needs attention, or do you need to fix your truck brakes in Langhorne, PA?

Though many people ignore their check engine light, you can improve your safety and your car’s lifespan by quickly addressing the problem. There are a variety of reasons why your check engine light might be on, including:

• A loose gas cap. One of the first things you should investigate when your check engine light is on is your gas cap. Remove your gas cap and screw it back on tightly. If this is indeed the problem, the light should turn off. If you notice that your gas cap is cracked or chipped, replace it as soon as possible.

• A failing oxygen sensor. This sensor measures the unburned oxygen in your exhaust system. Your oxygen sensor is crucial to your vehicle’s fuel economy and usage. If your oxygen sensor is failing, your car will get fewer miles to the gallon — and your check engine light might turn on.  

• A failing catalytic converter. Your car’s catalytic converter helps reduce the amount of pollutant gases your car releases into the environment while operating. If your catalytic converter is failing, you’ll almost always see your check engine light come on. A failing catalytic converter can also be the result of other issues with your car (like spark plugs or wires) because these work directly with the converter, so be sure to check these areas as well.
