Step #1: understand what the check engine light means

Before you further evaluate what needs to be done when you check engine light illuminates, you need to understand what this light means, how it will appear when you drive your car, and when it occurs.

As the name suggests, a check engine light indicates an internal issue in your vehicle that you must check immediately. While it might interpret that there is an internal problem in the engine, the check engine lights can be a general error related to a wide range of problems beyond the engine itself.

The check engine light might look like an engine illuminating with the word check on it, but in some instances, it might just say check engine in certain vehicles. You must familiarize yourself with what this check engine light will look like in your car so you take care of it when it happens.

Remember that sometimes when the heck check engine light illuminates, it doesn't look the same. In other words, sometimes the check engine light illumination could be a solid light, but in other situations, it might be a flashing light indicating a different type of problem.

Why You Should Keep Your Speed Sensors On Check

Step #2: familiarize yourself with the causes

Now that you've got an idea about the meaning of a check engine light, the next step is to understand what could trigger this check engine light to illuminate. Let's take a look at the common causes of an illuminating check engine light:

o   Cause #1: issues with the engine

The first and most common cause of triggering a check engine light is when you have a problem with the engine itself. The engine has a lot of internal moving components, and any of these components could go wrong and trigger the check engine light.

Therefore, it can take much work to tell where the problem is happening in the engine. For example, if you have an issue with the fuel injectors or probably in the cylinders, they might trigger a check engine light.

Considering that the check engine light illuminates because of an internal problem in the engine, it should tell you that you should never ignore the check engine lights illuminating. The more you wait on this problem, the more it evolves; it impacts other components around the engine, if not beyond the engine component itself.

o   Cause #2: loose parts

Interestingly, a check engine light might not indicate a significant problem in the vehicle. It might simply refer to a simple issue like a loose fuel cap! That is a very lucky situation, but unfortunately, it's not the most common one.

Therefore, you should not panic whenever you notice the check engine light illuminating because what it might take it's just tightening your fuel cap and moving forward. However, you should not only rely on this issue because, as we indicated before, the problem triggering the check engine light could also be more severe and might need immediate attention.

Some people might underestimate the importance of taking care of the check engine light just because they know it could be related to a minor problem. There is nothing to confirm whether the light is illuminating because of a minor or major problem, so we always recommend that you take it seriously and consult your mechanic as soon as possible.

o   Cause #3: issues with the sensors

With advanced technology, vehicles are getting more sophisticated. Manufacturers are adding a ton of sensors to help the vehicle operate the way you want and provide you with the best driving experience.

While this might be a great thing, it means that these sensors can go wrong, and with the increased number of sensors, it can be hard to tell which one is causing the issue. You should pay attention to the fact that when one of those sensors gets damaged, it might trigger a check engine light.

Therefore, be prepared for situations where your mechanic might recommend changing the oxygen sensor or replacing another sensor causing the check engine light to be eliminated.

So, one immediate action that you need to do to answer your question about what to do when they check engine light comes on is to replace the faulty sensor.

o   Cause #4: troubles with the transmission

Interestingly, even though the check engine light illuminates because of an issue with the engine, in many situations, the problem could be related to the transmission. Unfortunately, there is no specific light to say check transmission on your dashboard, so if your mechanic says you are dealing with a problem in the transmission, don't be surprised!

Sometimes an issue related to a dirty or low transmission fluid might result in problems triggering a check engine light to illuminate. These problems might not be directly related to the transmission, and they could be connected to the engine somehow and require the engine tilt to trigger the check engine light when they need to be fixed.

o   Cause #5: overheating troubles

Temperature is one of the worst enemies that could impact any vehicle. Your engine and the overall vehicle should operate within a certain temperature range. When the temperature exceeds this range, it can lead to significant problems, including destroying your engine!

If your vehicle feels that the temperature exceeds the maximum threshold, it will start complaining by showing various symptoms. One of those symptoms could be a trigger check engine light illuminating.

As a driver, you should be aware of all these symptoms to help yourself detect the overheating issue as soon as possible. The earlier you detect the problem, the easier it is for your mechanic to fix it without needing to install major components.

o   Allow your vehicle to cool down

Before you touch the vehicle end before you start exploring the car and around the engine components, it's important that you leave your vehicle to cool down for at least 30 minutes, all these components could be extremely hot.

o   Perform the necessary repairs
