Over the past decade or so, the cars have developed tremendously in the technology and there are basically signals and light for every little thing to notify and alert a driver about the car’s components.The check engine light of a car is connected to the car’s central computer system that helps it light-up for a wide range of reasons. It does not always mean that there is a major problem in the car or engine. It can light up due to minor issues as well like a loose gas cap.
CAUSES AND PROCESS
The check engine light signal appears on the dashboard (OBDII). It is a sort of monitor that looks after the performance of the parts connected to the engine light. If there is a problem with air pressure, air temperature, engine temperature, climate control, braking system or the electronic system the engine light might show up. When a problem is diagnosed in any of those areas, the check engine light will show up to notify and warn you. When you get notified the computer saves a “trouble code” in the memory as well. The code stored in the memory helps identify the component that has malfunctioned. The code is then read with a special scanning tool. This is how the check engine light functions and gives you signal of a malfunction or problem in the above named components.
HOW TO RESOLVE IT
When you see the check engine light on and if it is blinking, take the car immediately to an auto repair shop or hire a mobile mechanic to get it diagnosed. The expense of getting it diagnosed is reasonable, but the final expense depends on the problem that gets diagnosed. When you hire a mobile mechanic or take the car to an auto repair shop, the mechanic scans the trouble code to identify the problem. The diagnosis and repair do not take much time and can be solved on the same day as the repair might even be as simple as a wire change. This shows that you just need a day to get the check engine light problem diagnosed and resolved.
These are the basic things you need to know about the check engine light so that you don’t get scammed or too worried about it. It helps you get and idea of what to do in such situation.
