Simple reasons that cause the check bulb to light up in the car

Lighting the check engine bulb or what is called the Check engine is   a nightmare that many motorists flee from, especially those inexperienced, for fear of their car being exposed to serious malfunctions, but what some people do not know is that there are a number of very simple reasons that may be behind lighting this bulb in the car, This is what we will talk about in detail through the following lines:

Simple reasons that lead to the lighting of the check bulb  in the car:

1- Not tightly closing the fuel filler cap in the car:

As this leads to a defect in the fuel system in the car, thus increasing emissions in the car, which increases the rate of fuel consumption in the car and the lighting of the check engine light in the car, so in the event of exposure to this matter, it must be urgent to ensure that this part is tightly closed in the car, and look at him; It may suffer from cracks that lead to a leak, and therefore this symbol is illuminated on the car’s dashboard.
2 – Damage to the oxygen sensor in the car:

The damage of this part is one of the most important reasons that lead to the lighting of the check engine light in the car, as this part monitors the unburned oxygen that comes out of the exhaust, and the defect in this device means that it does not provide the correct data to the computer and causes an increase in fuel consumption. Most cars have between two and four of this part and the Scanner will show which one needs replacing, and this may cause the check engine light on cars to light up.

3- Damage spark plugs in the car:

The spark plugs seal the combustion chamber and provide the first spark for combustion to start in the engine. When the plugs fail, the spark plugs will not do their job either. You will feel a jolt during acceleration in your car, as it leads to the light of the check engine light in most cars.
