There is a small black cylinder pn the turbo assembly. This is the turbo controller/actuator. You should be able to hear this unit go through a self test when the key is turned on/off. The actuation rod will go through full range of motion during test. you can unplug actuator, (code will appear) and test drive to see if there is any power loss/change. if NO change then actuator is not working and turbo at fixed position.
The most common faults with 1KD-FTV engines are;
turbo & turbo actuator
injectors
EGR system
intake system carbon blockages.
