What causes the check engine light to turn on?

If there is a problem with your car, you will notice some obvious symptoms that indicate that it is a mechanical problem such as a loss of traction, a jolt or the hearing of strange sounds. But sometimes the appearance of a light bulb on the car keyboard (dashboard) is evidence of a problem, and it is very difficult to know what this problem is.

But there are some common reasons why your car’s engine light is on, even though the car is modern and running well. Unless you want to know how to diagnose the cause of the car engine light bulb and solve this problem, follow these directions

1. Why does the engine light work?

Lighting the bulb is a warning indicator in the engine of your car, it works in a similar way to an increased emissions test in a carWe are sure that the problem is related to a defect in the fuel system, so you find an increase in fuel consumption and often lead to bigger problems over time. It is better to take the car to the nearest maintenance center or a mechanic to help you and diagnose the problem.

1. It has become easy to diagnose the problem using the correct tools you have or with one of your friends, one of these tools is a car fault scanner, it is found in the shops or you can buy one for yourself at a fairly cheap price and before you buy it make sure that the model you will get is compatible with your car model and year of manufacture.

In order to diagnose the problem, all you have to do is connect this device to the connection port, which is often next to the driver’s foot, which in turn connects to the car engine, and the car computer will show the damage to this device and what appropriate measures must be taken early.

1. The first thing to check is when you see the engine light working, immediately check the tightness of your fuel cap and close it well and make sure that there are no cracks or damage to it, which is one of the reasons that lead to a fuel leak, the fuel cap is of paramount importance as it helps to maintain pressure in the fuel supply system.

1. Also, if this problem is not solved or you notice some problems in the general performance of the car, try to reduce the workload on the engine, taking into account driving gently and avoiding heavy loads or engine stress, and checking the car as soon as possible.

 If you follow these directions and the problem is not resolved and the engine light bulb is still working, you may need to replace some components including: oxygen sensors (oxygen sensor), spark plugs, your catalytic converter. Check these components for proper replacement parts and replace them immediately.
