To replace the Variable Speed Sensor (VSS) on a 2000 Infiniti I30, first, disconnect the negative battery terminal to ensure safety. Locate the VSS, which is typically found on the transmission; it may require removing other components for access. Unscrew the old sensor, install the new one, and reconnect any components you removed. Finally, reconnect the battery and test the vehicle to ensure proper operation.
Usually the VSS is located on the gear box. See if you can find it by looking between the firewall and the engine, sometimes it sticks out of the top of the gear box. If you speedo is not working it can be caused by three things, most likely the wiring connection is broken, secondly a broken speedo cluster, thirdly a broken VSS. But usually the VSS is quite robust because it is basically a magnetic sensor. Peter

To replace the vehicle speed sensor (VSS) in a 2000 Toyota Sienna, start by locating the sensor, which is typically found on the transmission. Disconnect the negative battery cable and remove any components obstructing access to the sensor, such as the air intake duct. Unplug the electrical connector from the VSS, remove the mounting bolt, and carefully pull the sensor out. Install the new sensor by reversing the removal steps, ensuring a secure connection and proper alignment.
The VSS is located on the top of the transmission and is connected to the engine wiring harness. To replace it all you need to do is unplug the old one from the wiring harness and unscrew it from the transmission, instalation is the reverse of removal.
No need to test VSS. If the check engine light is on and fault code is VSS; then replace same. Huge job best done by reputable shop.
