Common Causes of a Check Engine Light

There are tons of reasons the check engine light comes on, and there are often multiple reasons at once. Here are some of the most common things that can trigger your check engine light.


The reason for your check engine light could be as simple as not screwing your gas cap on tight enough the last time you filled up. A damaged gas cap could also trigger the light and reduce your fuel economy.


The oxygen sensor measures how much-unburned oxygen is in your vehicle’s exhaust system. The sensor may fail roughly every 80,000 miles. A bad oxygen sensor can damage your catalytic converter or spark plugs - a good reason not to ignore the check engine light.


The mass airflow sensor (MAF) measures how much air is entering the engine, determining how much fuel your engine needs to run properly. If your MAF is damaged, it can cause other parts to fail.


The catalytic converter converts carbon monoxide into carbon dioxide. If it’s damaged, your car will fail an emissions test and have lowered gas mileage. Often, problems with another part lead to catalytic converter damage.
