Basically, you need to use your mobile phone to record audio as well as record video. The purpose of using audio and video equipment is to record incidents on your vehicle. Usually, the videos will give you a clear record of the light spots so that you can easily spot them.

Next, one of the solutions to help you check the engine lights without using a scanner is to use an electric lock.
Electric locks seem not too strange to modern life today. Extremely simple, when using the electric lock, you need to turn on and off the car key without completely starting the car engine.

However, depending on the characteristics of individual vehicles, this on/off process will take place about 2-5 times and usually 5 times.

When you do this successfully, the key in the electric socket is in the “on” position. Then pay attention to the signal light; if you make a left or right turn and the light comes on, your code test was successful.

However, this may not work very well, and the engine will turn on again, and you will have to do it from scratch.

Use a meter

What Causes The Engine Lights To Glow?

What Causes The Engine Lights To Glow

As mentioned just before, the engine light is the light that signals the dangers that your car may encounter. So when your car’s lights come on, there are probably several reasons you need to pay attention to, some of which include:

Fuel cap malfunction

The first and quite common is that the fuel cap can malfunction. Of course, almost everyone knows that the fuel cap plays a significant role in maintaining a stable pressure in the fuel tank. Furthermore, you will ensure your fuel does not leak to the outside, thanks to the fuel cap.

However, if you install it loosely and fuel consumption also affects the transportation of the vehicle, it will sometimes cause the engine lights to glow. All you need to do is replace or inspect the cap immediately.

Affected oxygen sensor

When the engine light comes on, the next thing you need to pay attention to is the oxygen sensor. The oxygen sensor is a design that aims to measure the amount of oxygen released from your car’s exhaust.

When the sensor fails, your fuel may have lost over 40% through burning it. Not stopping there, some other parts may also be affected by this.

Faulty spark plugs and wires

When the engine light is on, you need to think about it because of the car’s spark plugs and wires. Maybe it’s broken or has some minor glitches. You probably already know that spark plugs are responsible for creating sparks so that they can ignite the fuel as efficiently as possible.

And, of course, when the spark plug fails, you can waste a lot of energy, and you need to do it and replace it if possible.

Air Flow sensor malfunction

Finally, one of the reasons why the engine light is on is that your airflow sensor has some problems. You can sometimes mistake it for an oxygen sensor.

However, the airflow sensor controls the entire amount of air that needs to be burned at the engine. If your engine light is on and it’s a problem with the airflow sensor shaft, consider having it repaired as soon as possible.
