Abstract
A temperature sensing system for an internal combustion engine includes a heat transfer element communicating with both the engine coolant passage in the cylinder head and the cylinder head itself. A temperature sensor is used to sense the temperature of the heat transfer element. During normal engine operating conditions, the system records engine coolant temperature. During a loss of coolant, the system records cylinder head temperature.
