Turn ignition off. Disconnect speed control servo connector C122 and Powertrain Control Module (PCM) connector C175. Measure resistance between speed control servo connector C122 terminal No. 3 (Gray/Black wire) and PCM connector C175 terminal No. 68 (Gray/Black wire). See Figure and Fig 1 . If resistance is 5 ohms or less, replace speed control servo. If resistance is greater than 5 ohms, repair open in Gray/Black wire. Retest system operation.
