Don’t panic if your check engine light comes on. It doesn’t necessarily indicate a serious problem. So, what does the check engine light mean? Let’s take a look at some of the possibilities.

Loose Gas Cap

Sometimes the check engine light comes on because there’s an issue with the gas cap. If it’s not on tight enough or not at all, or if it’s damaged, then the seal of the fuel system is compromised. The seal helps the pressure in the fuel tank stay consistent and prevents noxious fumes or hydrocarbons from being released into the air when you’re not driving your vehicle. You should fix this problem to avoid fuel evaporation and wasting gas.

Spark Plugs/Plug Wires Not Working

You need well-functioning spark plugs to ignite the mixture of fuel and air within the combustion chamber and plug wires to deliver the spark. When they’re not working properly, your engine suffers when it comes to performance and so does your fuel economy. Spark plugs and plug wires are examples of minor items that need routine maintenance to avoid causing more serious damage to your oxygen sensors, ignition coils, or catalytic converter.

Malfunctioning Mass Airflow Sensor

The mass airflow sensor monitors how much air enters your engine and gauges how much fuel is needed for maximum efficiency. When something’s going wrong, it can reduce your engine’s performance and result in poor gas mileage. The impact of a damaged mass airflow sensor can be seen in spark plugs, oxygen sensors, or the catalytic converter.

Broken Oxygen Sensor

A faulty oxygen sensor is another relatively minor cause for the check engine light to come on. If it’s not working properly, then the amount of unburned oxygen in the vehicle’s exhaust system will not be accurately measured. Don’t ignore this problem because it can cause you to lose up to 40% of your car’s fuel economy and burn more fuel than you need to. It can also cause damage to your spark plugs and catalytic converter, which could be a much more costly repair.

Damaged Catalytic Converter

Your vehicle’s catalytic converter turns carbon monoxide into carbon dioxide, protecting the environment from harmful emissions. If your catalytic converter is damaged, which can happen because of inconsistent vehicle maintenance and age, your vehicle will run at a higher temperature, fail emissions tests, and exhibit a poor level of performance. This is typically a major repair.
