If the "servo" in the throttle body is just a brushed motor (per the mention at the Infineon site), then controlling the position with pot might be fairly easy. Does the throttle plate have any position feedback?
Thanks for your help. Yes the plate has two position sensors. Both are 5V, but their range is reversed, at a given position the feedback from the two position sensors has to "match". This is the principle. The accelerator pedal features 2 potentionmeters.
