Testing Vehicle Speed Sensor

1. Vehicle speed sensor is located within speedometer assembly. Using an ohmmeter, check continuity between vehicle speed sensor terminals No. 1 and No. 2. See Fig 1 .
2. Slowly turn speedometer shaft. Ohmmeter indication should alternate between continuity and open circuit. If vehicle speed sensor is inoperative, replace speedometer assembly.
