2007 Chrysler Pacifica: Driving this morning on a cold engine on a cold morning about 4.5 miles after starting my engine, temp gauge shot from cold to the top of hot within just a second or two, temp light came on, along with the Electronic Throttle Light and OBD light in addition to a constant audible chime. I looked under the hood and don't see any leaking from the coolant housing or adjoining hoses. There is proper amount of coolant in the coolant housing and there is no fluids coming from the radiator. Please offer a diagnosis. Thank you in advance.
