Understanding the Service Engine Soon and Check Engine Lights
If you are a car owner, then you have probably seen the Service Engine Soon (SES) and Check Engine (CEL) lights illuminate on your dashboard at some point. These lights can be confusing, and many people wonder if they are the same or different. In this section, we will dive into the purpose and function of these lights and the difference between them.
Purpose and Function
Both the Service Engine Soon and Check Engine lights are warning lights that are designed to alert drivers to potential problems with their vehicles. When either of these lights comes on, it means that there is a problem with the engine or emissions control system. The lights are triggered by a module in the car’s engine that monitors various sensors and systems. When a fault is detected, the module stores a code in its memory and illuminates the warning light on the instrument cluster.
The purpose of the Service Engine Soon light is to remind drivers that their car is due for service. This light is usually yellow and will come on when the car has reached a certain mileage or time interval since the last service. The light is not an indication of a problem with the car but is rather a reminder to schedule maintenance.
The Check Engine light, on the other hand, is an indication that there is a problem with the car’s engine or emissions control system. The light is usually yellow but can sometimes be red. When the light comes on, it means that there is a fault code stored in the car’s computer. The code can be read using a diagnostic tool, which will provide information on the specific problem that is causing the light to come on.
Difference Between the Two Lights
The main difference between the Service Engine Soon and Check Engine lights is the severity of the problem they indicate. The Service Engine Soon light is a reminder that the car is due for service, while the Check Engine light indicates a fault in the engine or emissions control system.
Another difference between the two lights is the color. The Service Engine Soon light is usually yellow, while the Check Engine light can be yellow or red. A red Check Engine light indicates a more severe problem that requires immediate attention.
In summary, the Service Engine Soon and Check Engine lights are warning lights that indicate potential problems with a car’s engine or emissions control system.
