SPEH)SENSOR
Speed Sensor Testing
Test the speed sensor with an ohmmeter. Place the ohmmeter leads on the terminals in the sensor connector (Fig. 40).
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 (Fig. 40). 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.
Speed Sensor Replacement
Disconnect sensor wire harness connector.
Remove sensor retainer bolt and remove sensor
(Fig. 41).
Remove and discard speed sensor O-ring.
Install new O-ring on speed sensor and install
sensor in transmission case.
