Top 5 Reasons Your Check Engine Light Came On

It is important to get to know your dashboard lights. These indicators come on when there is problem, and they are not something you can ignore. Your car is trying to tell you something, and it can be frustrating and confusing. But if you do ignore it, you risk further damage to the car and might even put yourself at risk. Here are just a few of the most common reasons why your check engine light comes on:

1. Oxygen Sensor Needs Replacing
This is the most common car repair for six years in a row, and is one of the most common reasons for the check engine light. The O2 sensor monitors unburned oxygen from the exhaust. It can fail because of neglected repairs, engine problems, or even using gas with a higher ethanol concentration. And because the sensor works with the on-board computer, a malfunction can cause as much as a 40% decrease in fuel economy.

2. Catalytic Converter Needs Replacement
These are the second most common issues drivers face across the United States. This part works to reduces gases from the exhaust, converting carbon monoxide into harmless substances. If the catalytic converter fails you might notice reduced mileage or less power when you accelerate. If you keep up on routine maintenance, this part shouldn’t fail. But most often the failure is related to a deteriorated spark blog or broken oxygen sensor.

3. Gas Cap is Damaged, Loose, or Missing
Ever driven away from the pump with the gas cap still off? It happens to the best of us. You might not think it important, but the gas cap keeps gas vapors from leaking out. If it is missing, cracked, or loose it can throw off the entire fuel system. This will increase emissions and reduce gas mileage. Your car might also feel strange, a little jerky. If the light comes on pull over and check the cap. If you seal it tight and the light turns off, you have fixed the problem. If the light persists you might need to purchase a new gas cap.

4. Needs Replacement Mass Airflow Sensor
This sensor tells the on-board computer how much fuel to add based on the air coming through. It might fail if it was improperly installed, or if it hasn’t been replaced in a long while. Technically you can still drive the car, but the best solution would be to get your car in for auto repair as soon as possible.

5. Plug Wires or Spark Plugs Need Replacing
Last but not least, sparkplugs can also trigger the check engine light. These parts seal the combustion chamber and initiate the combustion. If the spark plugs misfire it could cause a jolt in the acceleration. New spark plugs might last up to 100,000 miles, And yet, they will wear out with time and use. Luckily it is affordable, and easy to replace spark plugs.
