Vehicle Speed Sensor (VSS)

1. Remove the vehicle speed sensor and connect a 3 - 10 K Ohm resistance as shown in the illustration at left.
2. Turn the shaft of the vehicle speed sensor and check that there is voltage between terminal (2) and terminal (3). (1 turn = 4 pulses)
3. If within the standard value, the vehicle speed sensor is OK.
If not within the standard value, replace the vehicle speed sensor.
