Bad Sender. Bad guage.
Most likely the problem is with the Pressure Sensor in the engine block.
If the check engine light is on a malfunction that is effecting the engine emission control system has been detected If the check gage light is on , either your engine coolant temperature is too high , your engine oil pressure is too low , or your gas gauge is at or near empty
Most likely, the temperature gauge's connection is loose. It is usually on the thermostat. An inoperative temperature gauge will cause most check engine lights to come on.
It's a common malfunction with the guage. Basically it's a poorly manufactured part and this happens when it goes out. It will require you to get a new fuel guage installed.

On a 2000 Dodge Ram, "no bus" means the communication network between modules has quit working. Any module on the network or the wiring between them can be the cause of the malfunction.
temperature gauge not working can be caused by a bad temp sensor in engine, a bad gauge in dash, or a bad fuse
No, low coolant would cause the opposite.
An inoperative temperature gauge will not alter how an engine runs, but the operator will not know if the water temperature has risen above normal without a properly working guage.
I have 2002 Aurora with the same problem.
The fuel control relay is mounted on the right fender, a foot aft of the battery. It is one of two cube-looking relays mounted there. It is controlled by the Electronic Engine control. Replacement is about $20.
It can cause rust;Gas gauge malfunctions, and even mess with your cars computer. Not good.
