Test TC-35C: No Vehicle Speed Sensor Signal
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION . For wiring diagram, see WIRING DIAGRAMS article.
- Turn ignition off. Using an ohmmeter, check resistance of VSS ground circuit at VSS connector. See VSS CONNECTOR WIRE IDENTIFICATION table. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open VSS ground circuit. Perform TEST VER-2A .
- Disconnect Powertrain Control Module (PCM) connector. Inspect PCM connector for pushed out or damaged terminals. Repair PCM connector as necessary. Perform TEST VER-2A . If PCM connector is okay, go to next step.
- Using an ohmmeter, check resistance of VSS signal circuit between VSS connector and PCM connector terminal No. 66. See PCM CONNECTOR WIRE IDENTIFICATION table. If resistance is less than 5 ohms, replace PCM. Perform TEST VER-2A . If resistance is 5 ohms or more, repair open VSS signal circuit. Perform TEST VER-2A .
