4 Reasons Why My Check Engine Light Came On

Uh oh, my check engine light came on. You possibly feel a sense of dread. No worries. Continue reading below to get a clue of what could be wrong.


My Check Engine Light Came On: What's Wrong?

The check engine light brightens when your auto's computer thinks there is an issue that might affect your vehicle's emissions control system.

When the light illuminates, a few diagnostic problem codes are in the vehicle's computer. These codes remain there even if the light disappears. To deal with a check engine light problem, you or your auto technician can get the codes by using a scanner and then troubleshooting to discover the issue.

Don't mistake the check engine light with the service or maintenance light. These lights brighten for expected routine services. Mileage and gas usage generate service lights. Get it analyzed by a mechanic.


What's Next: My Check Engine Light is On

Below are some typical situations: 

The Check Engine Light Flashes.

If the check engine light flashes in the city but goes off on the highway, then the issue is only occurring in city driving conditions. Pay attention to whether or not your car works any differently when you see the light. 

If you detect a difference, drive the car as little as possible and bring it to your mechanic. In this condition, you run the risk of your car dying. You don't want to be stuck on the side of the road, waiting for towing service. 


The Check Engine Light Comes On and the Light Remains Lit. 

If the check engine light is on continuously while driving with no visible issues, there is a fault in the emission control system. When this occurs, the computer that powers the emissions system will have your automobile working in a couple of lower gears. This idea is called "limp-home mode." Get your vehicle serviced immediately. 


The Check Engine Light Remains On and there are Performance Issues. 

This statement means that a crucial part of your emission control system has a significant issue. It typically is a component the automobile needed to function. In many instances, the car is not safe to drive at all. It can stop at any minute. It's advised to pull over to a safe spot and call emergency towing service.
