SPEED SENSOR TESTING
1.
Test the speed sensor with an ohmmeter. Place the ohmmeter leads on the terminals in the sensor connector.
2.
Rotate the transmission output shaft and observe the ohmmeter needle. The needle should deflect indicating the switch is opening/closing as the
rotor moves past the sensor. Replace the sensor if the ohmmeter does not display any kind of reading.
^
If a digital ohmmeter is. being used, the sensor should generate an ohmmeter readout each time the switch opens and closes.
