Abstract
Temperature measuring device for an internal-combustion engine comprising a main engine temperature sensor to measure the temperature of the cooling water, for example, and a secondary or auxiliary temperature sensor disposed near a heat generating element in an electronic engine control unit, as a standby for the main temperature sensor. When an output of the main temperature sensor happens to fall outside the predetermined normal range, the main temperature sensor will be immediately switched to the auxiliary temperature sensor to allow the various phases of engine control to proceed without interruption.
