Computer codes related to: on 2006 GMC Canyon

Received a letter from GMC regarding Valve Seat wear. I would think codes would be generated causing the Service engine lite to come on. I would like to find out what codes would be generated that would identify the problem with the valve seat wear.

I don't think valve seat wear would turn on the service engine light, what did the letter say to do about it?
Thanks for your effort, but the letter did state the service engine light would come on and I have since found out that it is a code of 0300, however my daughter has googled this and found that the code 0017 can be related to this matter as well.
