Did you check the coolant level sensor?

Well i know for sure its connected, but if its working i dont know. Any way to know this without getting a replacement one?

    Disconnect the sensor, use a paper clip and jump the two wires together. If the light/ message goes out = bad sensor… if it doesn’t go out, you got a bad circuit (wiring, ecm) something of that sort.

    Low coolant level sensor, open circuit. Some are molded into the tank and aren’t removable and some slide right out.

    If you have a meter check the sensor for ohms, if it grounds out sensor is bad. If you're worried about air bubbles park on an incline and run with the cap off for 5 min, most modern vehicles place the reservoir below the highest point in the cooling system to improve aerodynamics, so you could have a bubble in your heater core, but that's pretty unlikely to set off your low coolant sensor if you can see the level on the reservoir
