Vehicle Speed Sensor: Description and Operation
PURPOSE
Sensor provides a pulse signal interpreted as road speed and factored into various ECM calculations. Signal is also used by instrument cluster for road
speed display.
OPERATION
Sensor is a variable reluctance coil device producing a pulsed signal. Pulse frequency is calculated by ECM as road speed. Pulses are generated at the
rate of 7870 per mile (4920 per kilometer).
