Vehicle Speed Sensor (VSS)

Turn ignition off. Remove vehicle speed sensor from transaxle. Set voltmeter on AC range. Connect voltmeter positive test lead to vehicle speed sensor Pink/Blue wire terminal and negative test lead to Black/Red wire terminal. Turn vehicle speed sensor pinion gear while measuring voltage output. If voltage is about 0.5 volt, replace PCM. If voltage is not about 0.5 volt, replace vehicle speed sensor.
