Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to prevent any electrical shorts.

2. Inspect and Replace Vehicle Speed Sensor

Tools Required: Socket set, torque wrench, multimeter
Locate the vehicle speed sensor, typically found on the transmission.
Remove the connector from the speed sensor.
Use a socket to remove the speed sensor from its mount.
Inspect for wear or damage; if faulty, replace with a new sensor.
Install the new speed sensor by reversing the removal process. Torque the sensor to the manufacturer's specifications (usually around 10-15 Nm).
Reconnect the electrical connector securely.

3. Check Instrument Cluster Connections

Remove the instrument cluster from the dashboard.
Tools Required: Torx screwdriver set
Inspect the connectors and wiring for signs of corrosion or damage.
Clean any corrosion with electrical contact cleaner.
Reconnect the cluster ensuring a tight fit and reinstall it in the dashboard.

4. Reconnect Battery and Test

Reconnect the vehicle battery.
Start the engine and check the speedometer for functionality.
If the speedometer still does not work, further diagnosis of the cluster or wiring may be necessary.
