2010 Dodge Ram 4.7L, the computer is telling me it is overheating but the visual factors tell me it is not overheating. All parts changed, Radiator, water pump, changed twice, tensioner, clutch fan, thermostat changed out 3 times, temp sensor changed.

It would appear that there is no flow when running with cap off. I checked to make sure the plugs on the new radiator were off. Radiator has good flow as checked this weekend by a water test I did.

The engine seems to be holding at 235 to about 250 according to the computer. I dont hear any girg-aling to tell me engine is overheated. Using a thermo laser temp tester I find no parts over 190 degress anywhere on the engine.

Could the computer be going bad?

Thanks

Test resistance of the temp sending unit. (there should be a chart for that somewhere......) Also, is there only one temp sensor??? (I know some of the older trucks had two......)
