Four Reasons Your Check Engine Light May Be On

Don’t panic when your check engine light comes on.

Many people are familiar with the feeling of panic that happens when you’re driving and see the “Check Engine” light come on. While unsettling, there are a number of reasons why this little message lights up, and not all of them mean you’ll have to shell out thousands of dollars on a brand new engine. Here are five reasons your check engine light could be on.

Gas Cap

Your gas cap helps maintain pressure within the fuel tank and seals the gas system. It also prevents fumes from being released when the car is not in use. Your check engine light will be triggered if your gas cap is damaged, loose, or missing. You may lose fuel quickly and require more gas more often if it is not replaced.

Catalytic Converter

The catalytic converter converts carbon monoxide into carbon dioxide, helping to protect the environment from harmful substances. If the catalytic converter is damaged, your check engine light will come on. Your vehicle may run at a higher temperature if the catalytic converter is not replaced.

Oxygen Sensor

Your check engine light will also come on if your oxygen sensor is damaged and needs to be replaced. The oxygen sensor measures the amount of unburned oxygen in your car’s exhaust system. If not replaced, your spark plugs and catalytic converter may be damaged, and your engine will burn more fuel than needed.

Spark Plugs & Wires

Your check engine light may also come on if either the spark plugs or spark wires need to be replaced. Spark plugs ignite the mixture of air and fuel in your car’s combustion chamber, while the wires deliver the spark from the coil to the spark plug.

If, in the unfortunate circumstance, your vehicle needs a brand new engine—there are some cases in which buying a used car is a better option than replacing the engine. If a new engine is going to cost you more than the car is worth, or if your vehicle is very old, consider buying a used car from a dealership. With the money you make selling your car as-is, your out-of-pocket cost will be even lower. Buying from a used car dealership is a much safer option than buying from a private seller, due to the strict standards held by most dealerships. Do your research, determine your budget and the kind of vehicle you’d like, and then visit your used car dealership to take it for a test drive. You’ll be on the road again in no time!
