Vehicle Speed Sensor: Testing and Inspection
Raise vehicle wheels clear of ground before proceeding.
1. Turn ignition to ON and use a voltmeter to back probe pin 1 of C150.

3. Voltmeter reading should alternate between approximately 1 and 10 Volts.
4. If voltage is not correct, replace the vehicle speed sensor.
