How Can I Reset The Active Fuel Management System On My 2007 Chevy Impala Ltz?

I reset the avg economy  to zero the other day and later that day the check engin light came on. Autozone cleared the codes which were an oil pressure code and another related code. The car drives fine but when on the highway in cruise control the active fuel managment system does not kick it, the car stays in 6 cylinder mode. How can I reset the system to work again? Prior to resetting the avg economy there had never been a check engine light since I've owned the vehicle. It has 85,XXX miles on it and I've had it since 16,XXX.
