There is something wrong with the exhaust cam position sensor circuit and/or the exhaust cam position actuator circuit because the two aren't coinciding, that's what's setting the code.. You need a GM specialist to diagnose it and estimate for you. BTW: Going to the dealer and having the code erased and putting the light out doesn't fix anything.. If you want to see a specialist, here's a directory link for you: https://repairpal.com/directory?address=02360&car_brand_names=Chevrolet
