Engine flush done on my car 4 days ago and today my check engine light came on?

Hello,

The check engine light comes on when there is an issue with one of the car's computer monitored system. It could be a sensor for a mechanical failure or could be a issue with the emission system.

To find out why the light is illuminated, you will have to scan the vehicle for trouble codes. The process is very simple, if you do not have a scan tool you can take you vehicle to your local auto parts store and they can do the scan for you.

Here are is a helpful video:
