The thermostat is probably not opening or the water pump is not turning. Don't keep driving it like that, you will cook the engine.

run it and let it get hot (not to the point of overheating just let it warm up to normal or slightly above normal). put your hand near the upper radiator hose, if you feel not heat, touch it, be careful as it may be hot. if it is not hot at all but the engine is warmed up it is the thermostat, the thermostat is located where the upper radiator hose connects to the motor, usually a 2bolt metal fitting, if this is the case just replace the thermostat.

have you changed the sensor on the coolant reservoir? try that.
SOURCE: High oil pressure reading
Hi, this is a oil pressure sensor malfunction. the gauge is getting a distorted reading from the sensor. replacing the gauge will fix this issue. also, check the fuse box for blown fuses.
SOURCE: Temp gauge shows hot even if engine has been off overnight?
Locate the temperature sending unit and pull the wire off of it. Turn the key to the on position (do not start) then have someone touch that wire to a ground source and the temp gauge should go from one extreme to another (cold to hot). If the gauge does that, you have a bad sending unit...if it does not move, you have a bad gauge or problem with the wiring to the gauge.
All the temp sending unit does is act like a variable resistor depending on the coolant temp...if it is bad, it will give you a false reading.

is antifreeze dirty looking and if was changed was it chemically flushed?

Check top bottom hoses should feel about the same amount heat.If one cold thermostat probably not opening.Radiater can also block up.Waterpump if faulty youll normally get noise from it and if you hold fan blades with engine turned off see if you can rock it back and forward if lot play bearing shot replace pump.Always have engine turned off while checking
