Just bought a 2013 3500HD Duramax with 112000 miles on it when I looked at it had check engine light on at Dealership they worked on it removed code and said to drive it. Drove 70 miles today and check engine light back on with a P20EE code
Sound like it may me the indirect injector and NOS sensor in reading your posts
They can't work on it until next week will it go into limp mode or will it hurt to drive it until then ?
Thank you for adding me !

Welcome aboard. I have heard of some going into limp mode but by the truck doing that, it is protecting itself from potential damage. You can clear the code and see if it continues to come back. Not sure it applies to the 13 yr model but I know the L5Ps 17 and up see this and GM is working on a repair for it as it comes up quite a bit.

If I can be ever be of assistance, please don't hesitate to ask.

Take care,
