Vehicle Speed Sensor Function (For Analog Dash Only)

Turn ignition off. Remove instrument cluster. See VEHICLE SPEED SENSOR R & I in this article for instrument cluster removal. Disconnect speedometer cable from instrument cluster. Connect ohmmeter between Green/Red wire and Black wire. Slowly rotate speedometer cable connections at instrument cluster. If there are 4 continuity interruptions per speedometer cable rotation, proceed to PINPOINT TEST A5. If not, replace vehicle speed sensor (speedometer subassembly).
