In the drawing of the engine it shows a sensor in the side of the pipe (intake air after the turbo) near the intake manifold of the engine. If it has three wires (R, G, Y) then that's it. On that vintage engine the turbo boost is a tube running to the back of the injection pump, not an electric sensor.
Fantastic eyes, I never saw the sensor in the top left corner of the drawing, I will check it THANKS
