3 Causes for the Check Engine Light coming on



Keeping the vehicle in proper working condition is important. Even if you bring the vehicle in regularly and maintain the proper oil changes, unexpected breakdowns can happen. You might also notice if any of the dashboard warning lights illuminate. The most dreaded one is the check engine light, but sometimes the reason for this light coming on may be an issue that is not related to the engine. Some reasons can be a quick and easy fix, while other reasons may include parts being repaired or replaced.


One of the most common causes of the light coming on can be if the gas cap is loose fitting or missing. This allows vapors to escape from the fuel tank. When this happens, the check engine light may illuminate on your dashboard. This can also be one of the cheapest fix for why a check engine light turns on. If the gas cap is on tight, but the light keeps coming on, it is best to bring your vehicle in so we can inspect the vehicle and fuel cap thoroughly.


The oxygen sensor could be another reason for the light illuminating. Oxygen sensors measure the amount of unburned oxygen in the exhaust. It also helps to measure the amount of fuel in the tank of your vehicle. This information is then transferred back to your vehicle’s computer system. If it is not working properly, the light can illuminate on the dashboard.


Air flow sensors can set off the check engine light if they are in need of a replacement. These monitor the amount of air that the engine gets. This can then determine how much fuel is delivered. If the air flow sensor is not working properly, you may notice that the engine has less power. You may also notice or feel that your vehicle surges during any acceleration when driving. No matter what issue you notice with the vehicle, it is always recommended to bring it in so a proper inspection can be done. This can help you to have a comfortable ride.
