r2 is inside ECU
Pot1 is TPS
VIN is 5vdc all the time key on, this is power.
R2 holds throttle angle at zero, for safety so that if you drove car, and the plug fell of, no danger. see?
its called in electroncs, a R2 pull down restore
the ECT has a pull up resistors.,
the calibration is done so that the throttle is not stuck open in any why shape or form
that includes, things like , bad sticking throttle cables.
or gunk under the TV plate, it is assumed the plate is fully closed.
or the calibrations will fail.
on my H27, engine, there is a thermal valve that opens the TV (cold fast idle) , so I must do this hot engine, so that valve is working right, and TV is closed 100%
what I do is look at my TV , and say to self is it closed, with flash light, in hand.
if yes, it can be done just keyon.
