Vehicle Speed Sensor

Vehicle speed sensor is located on transmission/transaxle and contains a 3-pin electrical connector. Connect voltmeter and battery voltage and ground on electrical terminals of vehicle speed sensor. See Fig 1 and Fig 2.
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. Remove test equipment.
