And position sensor 6 is made up of two tongue tubes 7,8, guide rod 9 and housings 10 with magnet steel, and guide rod 9 vertically is close proximity near two tongue tubes 7,8 placed side by side, and in the housing 10 of packing into, simultaneously, a wherein end of guide rod 9 is fixed on the air throttle. When driver's accelerator pedal, guide rod 9 moves up and down, and makes tongue tube 7,8 adhesives or release, thus the level signal of exportable throttle position size.
This instrument also receives the frequency signal of engine speed from engine igniting coil negative pole 19 lead-out wires 20.
Because vehicle speed sensor 1 and engine igniting coil negative pole 19 lighting outlets 20 are pressed transducer 11,12 and comparator A with frequency respectively
