2010 cobalt limp mode

My 2010 cobalt ss is stuck in limp mode and reading PO119 and PO128 codes? Just put on new zzp upper intercooler pipe aswell. What could be my issue for these codes?

According to google, check your thermostat. Check the coolant temperature sensor and see if it's connected.

Should also check the wires leading to your map sensor. A lot of people get limp mode from that.
