    Abstract: PURPOSE: A variable geometry turbocharger control method is provided to normally drive a vehicle by controlling a variable geometry turbocharger by using a pressure sensor at the front end of a turbine without signals input from a boost pressure sensor as the breakdown of the boost pressure sensor or plausibility errors of the sensor.

The engine ECU controls the vane opening of the turbine by changing the target value to a pressure value of the front end of the turbine after reading the RPM of the engine and the amount of fuel in an abnormal mode of the boost pressure when errors of a boost pressure sensor value and other problems caused by sudden change are generated.
