Vehicle Speed Sensor

Vehicle speed sensor is located on transmission. See Fig 1-31. Connect voltmeter and battery voltage to vehicle speed sensor terminals. See Fig 3.
While rotating vehicle speed sensor shaft, ensure voltage changes from zero to at least 11 volts. Voltage should change 4 times per revolution of the shaft. Replace vehicle speed sensor if voltage does not change as specified.
