The Bosch engine ECU software calculates a model for the exhaust gas temperature at engine outlet valve. This modelled temperature signal is used as a virtual sensor for other software functions (such as EGR temperature model or boost control functionality) because the temperature sensor is not able to show fast temperature changes due to its slow dynamic behavior. Additionally, the sensor value is used for plausibility check of the temperature sensor.
