Vehicle Speed Sensor Test

1. Remove vehicle speed sensor from transaxle. Jumper a 3000-10,000 ohm resistor between sensor terminals No. 1 and 3. Connect battery positive voltage to sensor terminal No. 1 and battery negative voltage to sensor terminal No. 2. See Fig 1 .
2. Connect a voltmeter between sensor terminals No. 2 and 3. Manually turn speed sensor shaft. Voltage should pulse 4 times each revolution. Replace vehicle speed sensor if voltage is not as specified.
