を特徴とする車両制御装置の故障診断装置。 A fault diagnosis for a vehicle control device that includes a plurality of temperature sensors arranged in different parts of a vehicle engine and controls the engine according to detection signals output from these temperature sensors. The apparatus includes sampling means for sequentially sampling the output of each temperature sensor at a plurality of predetermined times when the engine is not operating, and calculating a convergence value of the output of each temperature sensor based on the sampling value by the sampling means. A failure diagnosis device for a vehicle control device, comprising a calculation means and a determination means for determining a failure of the temperature sensor by comparing these convergence values.
