Is your coolant level OK? If not, fill the reservoir to the "FULL" line first, then diagnose. Could be radiator, thermostat, waterpump, engine sensor, or just that coolant has leaked out or has been slowly evaporating away.

Thank you the coolant level was over filled I drained some of the coolant out. Changed the water pump thermostat radiator and hoses. Ran but was still over heating, took the thermostat out but it's still over heating. Thought it might be a head gasket, but it's still so much pressure in the top house just not sure

And I replaced the coolant sensor
