Claim:
1. A vehicle steering apparatus comprising: a steering unit including a steering reaction force motor capable of applying a steering reaction force to a steering member operated for turning a turning wheel of a vehicle; a turning unit including a turning motor configured to apply a turning force for turning the turning wheel, the turning unit being capable of turning the turning wheel while being mechanically disengaged from the steering unit; a clutch device including a switching actuator configured to mechanically engage and disengage between the steering unit and the turning unit; a temperature sensor configured to detect a temperature value of a temperature of one of the steering reaction force motor and the turning motor; and a control device configured to acquire a current integrated value of a current of the one of the steering reaction force motor and the turning motor, the control device configured to control, when the clutch device is in a disengaged state, drive of the turning motor such that a turning angle is in accordance with an operating state of the steering member and drive of the steering reaction force motor such that a steering reaction force in accordance with a turning state of the turning unit is applied, wherein the control device is configured to diagnose whether the temperature sensor is in a normal state: wherein the temperature sensor detects the temperature value of the steering reaction force motor, wherein the control device acquires the current integrated value of the current of the steering reaction force motor, wherein when the temperature sensor is diagnosed as being in the abnormal state, the control device diagnoses whether the steering reaction force motor is in an overload state based on the current integrated value of the current of the steering reaction force motor acquired by the control device:
