A self-diagnosis control system of a vehicle and a control method thereof are provided to self-diagnose components such as exhaust parts, etc. by measuring the additional outside temperature sensor is excluded. And the minute outdoor air temperature model value. A self-diagnosis control system of a vehicle and a control method thereof are as follows. The coolant temperature of the engine and the air volume inhaled to the engine is sensed(S10). Based on the signal which it is transmitted from the step of sensing the air volume and coolant temperature, the air temperature model value and the status is produced(S30, S50). The driving outdoor air temperature model value according to the running condition is produced with the calculated status(S70). |
