Test TC-35B - No Vehicle Speed Sensor Signal

WARNING: This page is about a different car, the 1996 Plymouth Breeze, 1996 Dodge Stratus, 1996 Chrysler Cirrus, 1995 Dodge Stratus, and 1995 Chrysler Cirrus. However, it is still accessible from the selected car via links, so may be relevant.
  1. Turn ignition off. Disconnect 3-pin Vehicle Speed Sensor (VSS) connector. Turn ignition on. Using scan tool in voltmeter mode, check voltage on VSS connector 8-volt power supply circuit Orange wire. If voltage is more than 7 volts, go to next step. If voltage is 7 volts or less, repair open 8-volt power supply circuit. Perform TEST VSS-VER - ROAD TEST VERIFICATION .
  2. Using scan tool, check voltage on VSS connector signal circuit White/Orange wire. If voltage is more than 4 volts, go to next step. If voltage is 4 volts or less, go to step  5.
  3. Connect a jumper wire to VSS connector ground circuit Black/Light Blue wire. Using scan tool, read VSS signal. While observing scan tool, tap other end of jumper wire to VSS connector signal circuit White/Orange wire. If scan tool displays more than zero MPH, go to next step. If scan tool does not display more than zero MPH, go to TEST TC-35C - NO VEHICLE SPEED SENSOR SIGNAL .
  4. Remove VSS sensor from transmission. Inspect speedometer pinion gear. If speedometer pinion gear is okay, replace VSS. Perform TEST VSS-VER - ROAD TEST VERIFICATION . If speedometer pinion gear is not okay, repair or replace as necessary. Perform TEST VSS-VER - ROAD TEST VERIFICATION .
  5. Turn ignition off. Disconnect Powertrain Control Module (PCM) connector. Using an external ohmmeter, check resistance of VSS signal circuit between VSS connector and PCM connector terminal No. 66 White/Orange wire. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open VSS signal circuit. Perform TEST VSS-VER - ROAD TEST VERIFICATION .
  6. Using scan tool in ohmmeter mode, check VSS signal circuit at PCM connector terminal No. 66 White/Orange wire. If resistance is less than 5 ohms, repair short to ground in VSS signal circuit. Perform TEST VSS-VER - ROAD TEST VERIFICATION . If resistance is 5 ohms or more, replace PCM. Perform TEST VSS-VER - ROAD TEST VERIFICATION .
