  3. If resistance is more than 5 ohms, using an external ohmmeter, check resistance of White/Orange wire between VSS connector and PCM connector terminal No. 47. If resistance is more than 5 ohms, repair open in White/Orange wire. Perform TEST VER-2. If resistance is less than 5 ohms, replace PCM. Perform TEST VER-2.
