Vehicle Speed Sensor: Testing and Inspection
Installed on the Transmission
1. Connect the Vehicle Speed Sensor Connector 1 (M-10) to the Battery positive (+) terminal and 2 (M-10) to the negative (-) terminal.
2. Connect a resistance of 1.3 k-ohm to 5.0 k-ohm (1/4W or more) between connectors 1 (M-10) and 3 (M-10).
CAUTION: Be extremely careful not to connect the Battery positive (+) terminal to the connector 3 (M-10). This may damage the Vehicle Speed
Sensor.
3. Rotate the shaft of the Vehicle Speed Sensor slowly and measure the voltage at both ends with a Digital Tester.
NOTE: The voltage, with one rotation of shaft, fluctuates four times in the following range : 10 to 14V <--> 2V or less.
Replace the Sensor when the result of inspection is found abnormal.
