Three Common Reasons For a Check Engine Light

Posted April 20, 2022

If you see your check engine light on when driving, you should get it checked out as soon as possible. A check engine light could mean something funky is going on with your car. It could be a minor problem or a big problem. Whatever the case may be, when the check engine light comes on, we need to give it attention to discover what needs to be done. Here are three reasons your engine light could be on.

Ignition and Combustion issues

The control module monitors your car’s ignition system. It comprises parts such as coil packs and spark plugs. If there is a problem with the ignition, the check engine light will be turned on to alert you.

Your car needs proper combustion of fuel and air to perform. However, it may have issues that prevent the engine from getting enough fuel or air. Sometimes, the systems may be faulty and cause more air or fuel than needed to enter the combustion chamber. In this case, the check engine light will be turned on to notify you of the problem. The best thing you do is to get it checked out immediately to avoid further possible issues.

Issues with Modules, Sensors, and Transmission Systems

Your car has many modules and sensors that work together for your vehicle’s optimal performance. If any of these sensors or modules are not working properly, the check engine light will be turned on to alert you. You will need to contact a car diagnostics technician to help you with this performance malfunction.

Transmission Isn’t Working Properly

The check engine light could also be on because the transmission system in your vehicle is not working correctly. The transmission systems manipulate the engine power and transfer it to the drive wheels on your machine. A problem with the transmission system can increase tailpipe emissions. The control module on your car will identify this problem and put the check engine light on.

If your check engine light is on, it indicates a problem with one or more parts of your engine. It’s time to take your car to a technician. Don’t ignore this problem or there could be big consequences. The longer you wait to act, the more costs you will probably incur.

Choose a reputable mechanic shop when getting your car checked out. According to, mechanics only become certified after passing one of 40 professional exams and earning a minimum of 2 years of experience.
