WARNING: This page is about a different car, the 1995 Plymouth Voyager, 1995 Plymouth Grand Voyager, 1995 Dodge Grand Caravan, and 1995 Dodge Caravan. However, it is still accessible from the selected car via links, so may be relevant.
  1. Turn ignition off. Using scan tool in ohmmeter mode, check resistance of VSS connector, sensor ground circuit (Black/Light Blue wire). If resistance is more than 5 ohms, repair open in Black/Light Blue wire. Perform TEST VER-2. If resistance is less than 5 ohms, go to next step.
  2. Ensure ignition is off. Disconnect and inspect Powertrain Control Module (PCM) connector for damaged, pushed-out or miswired terminals. Repair as necessary. Perform TEST VER-2.
  3. If connector is okay, use an external ohmmeter to check resistance of VSS signal circuit (White/Orange wire) between PCM connector terminal No. 647 and VSS connector. If resistance is more than 5 ohms, repair open in White/Orange wire. Perform TEST VER-2.
  4. If resistance is less than 5 ohms, put scan tool in ohmmeter mode. Using scan tool, check resistance of PCM connector terminal No 47, VSS signal circuit (White/Orange wire). If resistance is less than 5 ohms, repair short to ground in White/Orange wire. Perform TEST VER-2. If resistance is more than 5 ohms, replace PCM. Perform TEST VER-2.
