P2108 = https://www.autocodes.com/p2108_gmc.html

P1516 = https://www.autocodes.com/p1516_gmc.html

P1518 = https://www.autocodes.com/p1518_gmc.html

All the codes are related to the throttle actuator control module, start by inspecting the module connector for water. If the connector is OK, you may have to replaced the module.
