Description & Operation: Speedometer

Electronic speedometer receives signals from transmission-mounted 8-pole speed sensor. For each 8000 speed sensor pulses, speedometer electronics will increment the odometer 1 mile (1.6 km). Speed is determined by dividing input pulse frequency by 2.22 Hertz/MPH. The speedometer circuit electronics are calibrated to drive gauge pointer to a location in proportion to speed signal input frequency.
