PROBLEM TO BE SOLVED: To provide a control device increased in the frequency of detecting deviation of a hydraulic oil temperature sensor from a low pressure side range. SOLUTION: The control device 10 for controlling a transmission equipped in a vehicle is provided with: an input section 11 having input of at least signals from an engine water temperature sensor, an intake air temperature sensor and the hydraulic oil temperature sensor; and a microcomputer 12 executing a processing for determining that the hydraulic oil temperature sensor has provisional abnormality when hydraulic oil temperature settled by an input value of the hydraulic oil temperature sensor is not larger than a first threshold, when engine water temperature settled by an input value of the engine water temperature sensor and intake air temperature settled by an input value of the intake air temperature sensor are not smaller than a second threshold which differs from the first threshold by a predetermined value or more and when a difference between the engine water temperature settled by the engine water temperature sensor input valve and the intake air temperature settled by the intake air temperature sensor input valve, is not larger than a third threshold which is smaller than a predetermined value, and a processing for determining that the hydraulic oil temperature sensor has true abnormality when the provisional abnormality is determined a predetermine number of times or more.
