Hi,

I'm not sure what the code was, but it should eventually go off if the problem has been resolved. The vehicle (EGR System) will need to complete a predesignated drive cycle that can take several miles and start cycles to complete.

You can also clear the code. If the problem still exists, the light will return. Here is a link that explains how to turn it off:

Let me know if this helps or if you have other questions.

Take care,
Joe
