Speedometer Head: Description and Operation
How the Circuit Works
The indicator lights are controlled by different conditions in their associated systems. Refer to each associated system to see its entire schematic.
Speedometer and Odometer
The odometer and speedometer drive circuits receive pulses from the vehicle speed sensor (M/T) or PCM (A/T). The pulse rate increases as the car
accelerates. The frequency and duration of these input pulses are measured and displayed by the speedometer, odometer, and tripmeter.
