Component Test

VEHICLE SPEED SENSOR

To perform a complete test of the sensor and its circuitry refer to Powertrain Management/Computers and Control Systems/Testing and Inspection

Testing and Inspection

To test the component itself:





Test the speed sensor with an ohmmeter. Place the ohmmeter leads on the terminals in the sensor connector.

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.
