My RL check engine light showed up yesterday and threw up 3 codes

1: Engine Coolant Temperature (ECT) below thermostat regulating temperature

2: Idle speed high

3: Supercharger inlet pressure sensor performance

Any input would be nice, my uncle's helping me but a little busy right now so i wanna do as much as I can to help out, thanks.

Try removing and cleaning the throttlebody. Just a guess, and its east to do.
