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

They can't work on it until next week will it go into limp mode or will it hurt to drive it until then ?
