Vehicle Speed Sensor: Description and Operation
With the
ignition switch in
ON (II) or START (III), battery voltage is supplied through fuse 1 ('97 models) or fuse 4 ('98-'99 models) and the YEL ('97 models) or BLK/YEL ('98-'99 models) wire to the
Vehicle Speed Sensor (VSS). The sensor is grounded by the BLK wire to G101. The speedometer and other control units in the circuit supply about
5 Volts to the ORN wire (2.2L) or BLU/WHT (2.3L/3.0L) wire. The
VSS intermittently grounds the ORN (2.2L) or BLU/WHT (2.3L/3.0L) wire which generates a pulsed signal in it. The number of pulses per minute increases/decreases with the speed of the car.
