Test TC-35B - No Vehicle Speed Sensor Signal

WARNING: This page is about a different variant/trim than selected.
  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 .
